Venum's men's rashguards — long-sleeve and short-sleeve — share a single compression-fit table. The cut is deliberately tight to deliver a second-skin feel that locks the muscles in place during BJJ, MMA, no-gi grappling and rolling. The sleeves and torso are cut from the same stretch panels, so the same chart applies whether you're picking up a long-sleeve rashguard, a short-sleeve compression top or a tank-style cross-training piece from the Venum collection.
Fit tip: Rashguards are compression apparel — follow the size matching your measurements for that locked-in feel. For a lighter compression, choose one size above. If you're between two sizes, favour the chest measurement as your reference point.
| Size | Chest | Waist | Front Length | Sleeve Length |
|---|---|---|---|---|
| XXS | 34.6 - 35.8 in | 33.4 - 34.6 in | 19.3 in | 25.2 in |
| XS | 36.2 - 37.4 in | 35 - 36.2 in | 19.7 in | 26 in |
| S | 37.8 - 39 in | 36.6 - 38.2 in | 20.1 in | 26.8 in |
| M | 39.4 - 40.6 in | 38.6 - 39.5 in | 20.9 in | 27.6 in |
| L | 40.9 - 42.1 in | 40.2 - 41.3 in | 21.5 in | 28.3 in |
| XL | 42.5 - 45.3 in | 41.7 - 42.9 in | 22 in | 28.7 in |
| XXL | 45.7 - 49.2 in | 43.3 - 44.5 in | 22.6 in | 29.5 in |
Venum's published values are in inches — multiply by 2.54 to convert to cm if needed.
How to measure
- Chest: Measure around the fullest part of your chest, keeping the tape horizontal under the armpits.
- Waist: Measure at the narrowest point of your natural waistline, just above the hip bones.
- Front length: From the top of the shoulder seam down to the bottom hem.
- Sleeve length: From the centre back of the neck, across the shoulder, and down to the wrist with the arm slightly bent.
Not sure which size to pick? Sizing rashguards is forgiving thanks to the stretch fabric — if you're between sizes, go down for tighter compression or up for a more relaxed feel. We offer 30-day returns on unworn items with tags attached. Browse the full Venum collection for matching shorts, spats and compression gear.
