Choose a short- or long-sleeve rash guard by the amount of arm coverage you want, then check the exact garment's size guide. Venum's No-Gi 6.0 listings use the same stated fabric blend and care instructions for its two sleeve versions. The IBJJF uniform page specifies fit, torso coverage and color, so check the current rules for your division before competition.
The sleeve decision is about how much of the arm the garment covers. Compare the exact product specifications, then choose a size using that maker’s chart rather than a general shirt size.
Compare sleeve coverage
| Style | Coverage | Product details to compare |
|---|---|---|
| Short sleeve | Leaves more of the arm uncovered | Sleeve opening, hem placement and the garment’s stated fit |
| Long sleeve | Covers more of the arm | Sleeve length, cuff construction and the garment’s stated fit |
Venum’s No-Gi 6.0 short- and long-sleeve product pages list the same 81% polyester and 19% elastane blend, compression fit, round neck, reinforced seams, silicone inner band and care instructions. The listed difference to compare is the sleeve length; check the exact product page for the color and cut you want.
Measure for the garment, not a regular shirt
Use the maker’s measurements. Venum’s men’s rash guard guide asks for chest, front length, sleeve length and waist. Its listed No-Gi 6.0 product pages recommend sizing one to two sizes above the buyer’s usual size, but that is Venum’s recommendation for those models. Check the named garment’s chart before choosing.
For the larger no-gi clothing decision, see our BJJ rash guards, shorts and spats guide. The BJJ gi sizing guide covers gi fit and fabrics. Browse BJJ and grappling.
Check competition requirements
The current IBJJF uniform page says no-gi shirts must use elastic, skin-tight material and cover the torso to the shorts waistband. It also lists color requirements. The page does not list sleeve length as a separate no-gi uniform check, so review the current rulebook and event notices for the division before competing.

Common questions
Are short- and long-sleeve rash guards different in fit?
It depends on the model. Venum's No-Gi 6.0 pages list the same compression fit and fabric blend for its short- and long-sleeve versions, but check each garment's size guide.
Does IBJJF require long sleeves for no-gi?
The current IBJJF uniform page lists skin-tight elastic material, torso coverage to the shorts waistband and color requirements. It does not list sleeve length as a separate item on that page; check the current rules and event instructions for your division.
How do I size a BJJ rash guard?
Use the maker's chart and the measurements it requests. Venum's men's rash guard guide asks for chest, front length, sleeve length and waist measurements.
Do I need a different rash guard for competition?
