Breathable, quick-dry protection for hard rounds
$46.99
Built for BJJ and MMA, this rash guard uses a breathable, quick-drying knit that handles heat, sweat, and friction. The athletic, stay-put fit layers cleanly under a gi or runs solo for no-gi work. Standard thickness keeps coverage light without bulk. The pullover design keeps it simple from warmups to hard rolls, session after session.

Built for people who roll, the Crucible handles daily BJJ and MMA training: drilling, positional sparring, hard rounds, and no-gi work. It also layers cleanly under a gi for heat, grip fights, and long sessions without bunching. The knit breathes when the room gets humid and dries fast between rounds, keeping focus on grips and transitions, not your kit. Good for open mats, comp classes, and conditioning where you need coverage without bulk.
Cut is athletic and stay-put. Choose your usual compression-top size for a close, locked-in feel; if you’re between sizes or broad through chest and shoulders, size up for easier on/off. If you like a skins-tight fit, pick the smaller of two. Hem length runs slightly extended to stay under a belt line and waistbands during scrambles. Works for most body types across S to 5XL without riding up or flaring at the sleeves.
The breathable, quick-dry knit balances stretch and support at a standard thickness, so protection feels light and never bulky under a gi. Smooth seams and a simple pullover design cut down on distractions and friction when frames, collar ties, and mat contact add up. The fabric sheds sweat quickly between rounds and keeps moving when soaked, so clinch work and long chains don’t leave the top heavy or sagging.
Rinse after training, cold machine wash with mild detergent, inside out. Hang dry; skip heat, bleach, and fabric softeners. Keep it away from rough hook closures to limit pilling. With straightforward materials and a standard-thickness build, durability comes from consistent care and not over-drying. Within Apollo’s rash guard line, Crucible is the clean, everyday option for hard rounds; other models offer alternate aesthetics and cuts if you want a different look or feel.
