Online BJJ Gi shopping is a minefield.

The product photos look great. The description says "competition grade." The reviews seem solid. Then the box arrives and the collar is stiff as a board in the wrong way, the sleeves are already borderline short, and the logo is screen-printed — which means it'll be peeling off by month two.

At Bolton, we've spent 18 years on the manufacturing side. We know exactly what corners get cut, what specs get faked, and what red flags buyers miss because they don't know what to look for. Here are the 7 things you must verify before placing a BJJ Gi order online — whether you're buying one for yourself or 500 for your brand.

This is the single fastest quality filter available to any online buyer.

GSM (Grams per Square Meter) is the objective measure of fabric density. A manufacturer confident in their product will list it clearly. A manufacturer cutting corners will hide behind vague terms like "heavyweight," "competition grade," or "ultra-durable" — with no number attached.

What the numbers mean:

• 450–550 GSM for the jacket (pearl weave): Competition-ready. Dense enough for grip resistance, balanced enough for movement.
• 250–280 GSM for the pants (ripstop): The industry standard for durability without dead weight.
• Below 350 GSM jacket: Fine for casual training, but won't hold up under competition pressure or daily hard rolling.

If the listing doesn't give you a GSM number, ask. If they can't answer, move on.

Shrinkage is the number one hidden defect in budget BJJ Gis. A Gi that hasn't been pre-shrunk at the factory can shrink 3–7% after your first wash. On a size A2, that's the difference between a Gi that fits and one that fails IBJJF sleeve inspection.

What to look for:

• The listing should explicitly state "pre-shrunk" — not just "shrink-resistant."
• For bulk orders, ask your manufacturer for shrinkage test data. At Bolton, our pearl weave Gis are controlled to a ±1% shrinkage tolerance — a spec we can back up with production data.
• If a brand can't tell you their shrinkage rate, that's your answer.

Not all weaves are created equal, and the right choice depends on how and where you train.

• Pearl weave: The competition standard. Dense, durable, grip-resistant. Runs 450–550 GSM for the jacket. Expect a 5–10 wash break-in period before it softens fully.
• Single weave: Lighter and more affordable. Good for beginners and casual training, but less durable under competition stress.
• Double weave: Extremely durable but heavy. Less common in modern competition Gis because of weight limit concerns.
• Ripstop pants: The correct pairing for any quality pearl weave jacket. 250–280 GSM, tear-resistant grid construction, faster drying than cotton twill.

If a listing describes the jacket as "pearl weave" but doesn't specify the pant fabric separately — ask. Pants and jackets should always be specced independently.

This is the detail most buyers overlook — and the one that reveals quality fastest.

• Embroidery: The gold standard for Gi jackets. Thread stitched directly into the fabric. Doesn't crack, peel, or fade. If the chest logo is embroidered, that's a good sign.
• Woven patches: Acceptable and IBJJF-compliant when properly seamed. Look for clean edges and tight stitching around the patch perimeter.
• Screen printing on the jacket: A red flag. Cotton doesn't hold screen-printed ink under the friction and repeated washing of BJJ training. If the jacket logo is screen-printed, it will peel — usually within 60 days of regular use.
• Sublimation on rash guards: The correct method for synthetic performance wear. Ink fused into the fiber — no peeling, ever. At Bolton, sublimation is our standard for all rash guard and shorts production.

Check the product photos carefully. If you can see a slightly raised, flat graphic on the jacket (especially on the collar or chest), that's screen printing — not embroidery.

Even if you're not competing yet, buying a compliant Gi from day one means you'll never need to replace it when tournament season comes around. Here's what to verify:

• Color: White, Royal Blue, or Black only. Top, pants, and collar must all match.
• Sleeve length: Must come within 2 cm of the wrist when the arm is extended.
• Collar thickness: Must not exceed 1.3 cm.
• Sleeve and pant opening: Must allow a 7 cm diameter grip at full extension.
• Fabric: Must be cotton or cotton-like woven fabric. No stretch or synthetic-dominant constructions.
• Patches: Cotton only, properly seamed, in IBJJF-authorized zones.

A legitimate manufacturer will either confirm IBJJF compliance outright or provide the spec sheet measurements for you to verify. If neither is available, assume it's not compliant.

Seams are the structural backbone of any Gi. They're also the first thing to fail on a poorly made one.

What to look for in product photos:

• Reinforced or double-stitched seams at the underarms, collar junction, and crotch — the three highest-stress points on any Gi.
• Flatlock stitching on the inner seams — especially visible on pants. Flatlock seams lay flat against the skin and don't dig in during movement.
• Clean collar construction: The collar should be firm and uniform, with no visible gaps or uneven stitching at the base where the collar meets the jacket front.

If product photos don't show seam detail — ask for close-up shots before ordering. Any manufacturer worth working with will provide them.

This one applies whether you're buying one Gi or placing a bulk order.

• For individual purchases: A brand that stands behind its sizing accuracy will offer exchanges on unworn Gis. No exchange policy on sizing is a red flag — it usually means they know their sizing is inconsistent.
• For bulk B2B orders: Your manufacturer should provide a detailed size spec sheet with exact measurements — chest width, jacket length, inseam length — before production. At Bolton, we provide full measurement breakdowns for every size in our range, from A00 to A5, F0 to F4, M000 to M4.
• Pre-production samples: For any order over 50 units, always request a production sample before approving full run. A manufacturer who won't provide a sample is a manufacturer who isn't confident in their own output.

Here's the fast checklist before you hit order on any BJJ Gi:

• GSM listed clearly? √ (450–550 jacket / 250–280 pants)
• Pre-shrunk treatment confirmed? √
• Weave type specified for both jacket and pants? √
• Logos embroidered or properly seamed patches — not screen printed? √
• IBJJF compliance confirmed or measurable specs provided? √
• Reinforced seams visible in product photos? √
• Clear sizing policy and measurement spec sheet available? √

If you can check all seven, you're buying a Gi built to last. If you're missing more than two, keep looking.

The same checklist applies — but the stakes are higher. A bad Gi for your brand means returns, negative reviews, and customers who don't reorder. A bad Gi for your academy means athletes who are uncomfortable, non-compliant, and unhappy.

At Bolton, every Gi we produce hits every point on this list — by design, not by accident. Eighteen years of manufacturing has taught us exactly where quality breaks down, and we've built our production process to prevent it at every stage: fabric sourcing, pre-shrink treatment, seam reinforcement, logo application, and multi-stage QC before anything ships.
