Grays field hockey sticks – the AC, DB, GT, JB, MB, PB series and the Dynabow, Jumbow, Probow, Ultrabow profiles: 31 models from our range

This is a follow-up to the post How to read the names of Gryphon, Ritual and TK sticks. That text breaks the names of three brands down into family, profile and number; Grays was not in it. We make up for that here: Grays field hockey sticks in our range are 31 models marked Outdoor in six series (AC, DB, GT, JB, MB, PB) and five profiles (Dynabow, Jumbow, Probow, Midbow and Ultrabow, that is, GT), at prices from PLN 216 for the junior GT0Xi Ultrabow Junior to PLN 1,983 for the DB10+. We show how to read the profile and level of a stick from the name alone, what the product pages say about bow, composition and lengths, and which models are for whom according to the manufacturer.

The data comes from the product pages in our shop as of October 2026, the prices from product pages checked on 10 November 2026, and the list of 31 models was compared the same day with the sticks category in the shop. Check the product page for current lengths, colours and prices. Three product pages (JB5, PB9, PB10) give neither composition nor profile, and nine product pages of the Xi generation have Outdoor in the “Variant” field while their descriptions talk about indoor play; we cover that separately below and take from those pages only what is unambiguous.

How to read a Grays stick name: letters, number, plus and Xi

A Grays stick name consists of the series letters, a number and an optional suffix. In our range there are four elements to decode:

• Letters = series and profile. DB is Dynabow, JB is Jumbow, PB is Probow, MB is Midbow, GT is the standard profile, which the Xi generation product pages call Ultrabow, and AC is the AeroCore family with a foam core and the Dynabow-S profile. The series tells you straight away where the bow of the stick lies.
• Number = carbon level within the series. According to the product pages the number rises with the carbon fibre content: the DB6 has approx. 65% carbon, the DB8 approx. 85%, the DB10 the highest content in the DB series; in the JB series number 10 is the highest content, in PB+ number 11. A lower number is a more forgiving stick, a higher one a stiffer response on the hit. The product pages do not give percentages for every model, so where there is no figure we write “not given on the product page”.
• Plus = a refined version of the series. JB+ and PB+ are, according to the product pages, the extended Jumbow Plus and Probow Plus series; for the JB+12 the page links the plus to a modified head profile for the drag flick, for PB+ to aramid fibres added to the matrix. DB9+ and DB10+ are variants within the DB series.
• Xi = the Xi generation. Nine models with the Xi suffix (DB2Xi, DB4Xi, DB5Xi, DB7Xi, GT0Xi, GT0Xi Junior, JB3Xi, JB6Xi, PB10Xi) are marked Outdoor on the product page, but the descriptions talk about indoor sticks. The name carries the profile just as in the other series.

Then there is the head, which the product pages describe with three words: Micro (low-set, in DB, GT, MB and PB, according to the pages it makes carrying the ball easier), Maxi (in the JB series, combines a low profile with a large contact area) and Vertex (AC400, for carrying and a clean hit). The Xi generation pages divide heads into small (micro) and large (maxi).

Five Grays profiles in millimetres

What low, mid and standard bow mean at all is explained in the post Stick bow: low, mid, standard – what it really means. Grays names its profiles its own way, and the product pages give figures for them:

• Dynabow (DB, AC series): depth 24.75 mm, peak 250 mm from the head; the product pages describe it as a mid bow close to neutral, which “forgives more than a low bow while still giving a reserve of power”. The AC400 has the Dynabow-S variant with the same figures.
• Jumbow (JB, JB+ series): depth 24.75 mm, peak 200 mm from the head; a high-intensity low bow, according to the product pages set up for 3D, the drag flick and aerial play; the JB+12 page notes that the depth is almost at the limit of the permitted profile.
• Probow (PB, PB+ series): depth 24.75 mm, peak “close to the head” (the PB7 page gives no millimetres), a steep Micro head; according to the product pages the most intense Grays profile, for 3D skills and reverse-side control. The PB10Xi page calls it the lowest of the Grays profiles.
• Standard (GT series, on Xi pages: Ultrabow): depth 22 mm, peak 300 mm from the head; according to the product pages the simplest profile in the range, closest to a straight curve, for beginners.
• Midbow (MB series): depth 24.75 mm, peak 300 mm from the head, a concave back; according to the product page a compromise between a straight profile and an aggressive low bow, for control and accuracy.

It is worth noting that Dynabow, Jumbow and Midbow share the same depth of 24.75 mm and differ in the position of the peak: 200 mm (Jumbow), 250 mm (Dynabow) and 300 mm (Midbow) from the head. The closer to the head the peak of the curve lies, the “lower” the profile and, according to the product pages, the more it rewards lifting the ball at the cost of simple receiving.

The DB series (Dynabow) and the AC400: seven sticks on a mid bow

Dynabow is a series for the all-round player and the midfielder, as the product pages put it: one stick for carrying, passing, hitting and receiving. Six models have full data:

• Grays DB5 – for PLN 516, length 37.5 inches, carbon from the middle of the series with graphene; according to the product page for a player moving up to intermediate level who needs a stiffer response than the DB4 but not the top of the series.
• Grays DB6 – for PLN 538, 36.5 and 37.5 inches, approx. 65% carbon with graphene; for an intermediate player who plays regularly, “noticeably stiffer and more powerful on the hit” while keeping tolerance for mistakes. Colours black-blue and black with metallic pink.
• Grays DB8 – for PLN 1,032, 36.5 and 37.5 inches, approx. 85% carbon with graphene; for an advanced all-round player who wants power and a quick response but prefers a neutral mid bow to a low bow.
• Grays DB9+ – for PLN 1,419, 36.5 inches, carbon from the upper part of the series (above the DB8, below the DB10); for an advanced player close to the top of the series.
• Grays DB10 – for PLN 1,851, 37.5 inches, and Grays DB10+ – for PLN 1,983, 36.5, 37.5 and 38.5 inches: the highest carbon content in the DB series with graphene, according to the product page for an advanced all-round player or midfielder who “values the balance between control and power”.

Grays AC400 for PLN 645 (36.5 and 37.5 inches) stands beside the DB series: the AeroCore family with an aerospace-grade foam core which, according to the product page, absorbs vibration and stabilises the head, a Dynabow-S profile and a Vertex head, Light weight class. The page aims it at an intermediate player in an all-round or midfield position. All DB and AC sticks have the Light (L) class in the “Weight” field; the pages give no grams.

The JB series (Jumbow): a low bow for the drag flick

Jumbow is, according to the product pages, a classic “used by many international players”: a profile set up for power, the drag flick and aerial play, with a Maxi head. The pages aim the whole series at forwards, attacking players and drag flickers, and the low bow “requires technical skill”.

• Grays JB6 – for PLN 580, 36.5 and 37.5 inches, the middle carbon level in the series; for an intermediate forward who “is moving into power play” but does not yet need the JB8–JB10.
• Grays JB8 – for PLN 1,032, 36.5 inches, the upper part of the series; for an advanced forward or drag flicker who wants a stick close to the top without the price of the JB10.
• Grays JB10 – for PLN 1,505, 37.5 and 38.5 inches, the highest carbon content in the JB series, a graphene matrix; for an advanced forward who “wants to dominate the ball”.
• Grays JB+9 – for PLN 1,419, 37.5 inches, and Grays JB+12 – for PLN 1,935, 36.5, 37.5 and 38.5 inches: the Jumbow Plus series. The page describes the JB+12 as “the most energetic model in the Grays collection” for the 2026/27 season, with a solvent-free core and a modified head profile for drag flicks; for advanced and elite players, “not for beginners”.
• Grays JB5 – for PLN 433, lengths 34 and 35 inches; the product page gives only the mint colour and a general description, with no profile, composition or level. The name implies the Jumbow series in junior lengths; more on it below.

The PB series (Probow): the most intense profile

Probow is, according to the product pages, a profile “for the technician”: a midfielder or attacking player who carries the ball a lot, performs 3D moves and needs a stick that is sensitive on receiving and powerful on the backhand.

• Grays PB7 – for PLN 774, 36.5 inches, approx. 60% carbon plus graphene, aramid/kevlar and resins; for an intermediate to advanced player who puts control with the ball in 3D first.
• Grays PB+9 – for PLN 1,419, 36.5 and 38.5 inches, a high carbon content with graphene and aramid fibres; for an advanced technician who wants a top-shelf Probow without the price of the PB+11.
• Grays PB+11 – for PLN 1,716, 37.5 and 38.5 inches, the highest carbon level in the PB+ series; according to the product page the flagship Probow “with maximum stiffness and response on the hit”.
• Grays PB9 – for PLN 1,300, 36.5 and 38.5 inches, colour black and white, and Grays PB10 – for PLN 1,511, 36.5 inches, colour black with fluo yellow: both product pages have only a general description, with no composition, profile in millimetres or level. The name implies the Probow series with numbers between the PB7 and the PB+11; check the product page for details.

The GT series (standard profile) and the MB7

GT is, according to the product pages, “the simplest, most traditional profile in the Grays range”, an entry stick for beginners: children, juniors and adults learning the game. All three GT models have the same construction description: an entry-level composite with aluminised fabric in the matrix, a Micro head, Light class in the senior versions.

• Grays GT3 – for PLN 317, lengths 30, 31, 32, 33, 34, 35 and 36.5 inches, colours purple and mint; the only Grays stick in the range that covers children's lengths and a senior length in one model.
• Grays GT5 – for PLN 635, 36.5 and 37.5 inches, red.
• Grays GT8 – for PLN 1,269, 36.5 and 37.5 inches, blue; according to the product page the top model of the GT line.

The GT3, GT5 and GT8 product pages give no carbon content, so we do not describe the difference between them with a figure; the number works here as in the other series, from the entry-level 3 to the top 8. Grays MB7 for PLN 774 (36.5 and 37.5 inches) is the only Midbow series stick in the range: carbon with graphene, a concave back that increases torsional stiffness, for an all-round player or midfielder who “puts control and precision above maximum power”.

The Xi generation: what the product pages say, and what we do not know

Nine sticks with the Xi suffix have Outdoor in the “Variant” field, which is why we count them among the 31 models for grass. Their descriptions, however, talk about a “composite indoor stick of the Xi generation” and indoor play. We have reported this discrepancy for clarification; until then we take only lengths, colours and prices from the product pages and read the profile from the name.

• Dynabow Xi: DB2Xi for PLN 346 (blue-green), DB4Xi for PLN 563 (navy-silver), DB5Xi for PLN 649 (rose gold with silver), DB7Xi for PLN 912 (red); all in 36.5 and 37.5 inches. The DB2Xi and DB4Xi pages mention a large head (maxi), the DB5Xi and DB7Xi a small one (micro).
• Jumbow Xi: JB3Xi for PLN 433 (amaranth-blue) and JB6Xi for PLN 793 (blue-silver), 36.5 and 37.5 inches.
• Probow Xi: PB10Xi for PLN 1,191 (black-orange-silver), 36.5 and 37.5 inches.
• Ultrabow Xi: GT0Xi for PLN 260 (36.5 and 37.5 inches) and GT0Xi Junior for PLN 216 (32, 33, 34 and 35 inches), both red-coral; the product pages describe the GT profile as the simplest, for learning the basics.

31 Grays sticks in one table

Lengths according to the “Length” field on the product page (these are the variants you can choose in the shop; the descriptions of some pages also mention 38.5 inches, which is not among the variants). Composition and level according to the product pages; “not given” means no data on the page.

Grays sticks for a child and a junior

How to choose the length, bow and material of a stick for a child we described in the post A field hockey stick for a child – how to choose length, bow and material. In the Grays range three models have lengths below 36.5 inches:

• Grays GT3 for PLN 317 – from 30 to 35 inches plus 36.5; a standard profile which, according to the product page, “consolidates the basics: a clean hit, an accurate pass, confident carrying”. A child who grows moves on to the next length in the same model.
• Grays JB5 for PLN 433 – 34 and 35 inches, mint colour; the product page does not describe the profile, the name implies Jumbow, that is, a low bow. For a junior who already plays and wants a profile for lifting the ball; the profile is not confirmed on the product page.
• Grays GT0Xi Ultrabow Junior for PLN 216 – 32, 33, 34 and 35 inches, red-coral; the cheapest Grays stick in the range, with the reservation from the section on the Xi generation.

For an adult beginner the GT product pages point directly to the same series: the GT3 in 36.5 inches or the GT5 and GT8 in 36.5 and 37.5. The size guide in the shop helps match length to height; we do not carry over height figures from the Grays pages, because the pages do not give them.

How to choose a Grays stick in four steps

• Step 1: profile by position and style. All-round player and midfielder – Dynabow (DB, AC400) or Midbow (MB7). Forward and drag flicker – Jumbow (JB, JB+). Technician playing 3D and on the reverse – Probow (PB, PB+). Beginner – GT.
• Step 2: number by level. The “Level” field on the product pages: beginner – GT3, GT5, GT8; intermediate – AC400, DB5, DB6, JB6; intermediate and advanced – MB7, PB7; advanced – DB8, DB9+, DB10, DB10+, JB8, JB10, JB+9, PB+9, PB+11; advanced and elite – JB+12. A higher number is, according to the product pages, a stiffer response and a smaller margin for technical mistakes.
• Step 3: length from the product page. The senior lengths in this list are 36.5 and 37.5 inches; 38.5 is only on the DB10+, JB10, JB+12, PB+9, PB+11, PB9. Only 36.5 on the DB9+, JB8, PB7 and PB10; only 37.5 on the DB5, DB10 and JB+9.
• Step 4: budget. Entry into a series costs from PLN 317 (GT3) through PLN 516–580 (DB5, DB6, JB6) to PLN 774 (PB7, MB7); the top of a series is PLN 1,419–1,983. Xi models from PLN 216 to PLN 1,191 with the reservation about the descriptions.

Every Grays stick comes to you by courier, because sticks do not fit in a parcel locker; a grip for your own hold you will find in the category hockey stick grips, and a cover in the category stick bags and backpacks. If you are torn between two numbers of the same series, a question with your position, level and current stick goes through the Contact page. All 31 models are in the category field hockey sticks.
