Find your fit.
Sizing is intentionally conservative — built to perform under a gi. If you're between sizes, size up. If you're brand new and unsure, message us with your height and weight and we'll talk you through it.

Warrior Rash Guard
Long sleeve and short sleeve options. 4-way stretch — runs compression-fit. If you prefer a looser drape, size up one.
| Size | Height | Weight | Chest |
|---|---|---|---|
| S | 5'4"–5'7" | 130–155 lb | 35–38" |
| M | 5'7"–5'10" | 150–180 lb | 38–41" |
| L | 5'10"–6'1" | 175–210 lb | 41–44" |
| XL | 6'1"–6'4" | 200–240 lb | 44–47" |
Founder's Gi
IBJJF-approved sizing, A1–A4. Pearl weave 450gsm. Gis shrink roughly 3–5% after the first hot wash — that's factored into the chart. Wash cold and hang dry to minimize it.
| Size | Height | Weight |
|---|---|---|
| A1 | 5'3"–5'7" | 135–155 lb |
| A2 | 5'7"–5'10" | 155–180 lb |
| A3 | 5'10"–6'1" | 180–210 lb |
| A4 | 6'1"–6'4" | 210–250 lb |
Bowie Hoodie
400gsm heavyweight fleece, drop-shoulder cut. Sized for layering over a rash guard. If you want it slimmer, size down; if you want roomy streetwear fit, size up.
| Size | Chest (relaxed) | Body length |
|---|---|---|
| S | 42" | 27" |
| M | 44" | 28" |
| L | 46" | 29" |
| XL | 48" | 30" |
