Apollo Flux Rash Guard Set — S–4XL No-Gi Rash Guard & Spats Set

Choosing the rashguard-kit

The Apollo Flux Rash Guard Set is for people logging steady no-gi and MMA training who want a straightforward kit that performs every round. The short-sleeve top and matching shorts stay comfortable through drilling, positional work, and scrambles, with a smooth exterior that won’t drag on the mat. It pulls double duty for conditioning and cross-training days as well, drying fast between efforts and staying light when the room heats up.

Expect an athletic, close-to-skin fit that reduces grip and extra fabric. Sizes run from S to 4XL. If you’re between sizes, choose by chest for the top and by waist/hip for the shorts. Broader shoulders or stronger thighs may prefer the larger option for comfort. The rash guard should feel snug when dry and ease slightly as you warm up; if you want a bit more room, size up rather than forcing a tight pull.

The set uses a breathable, quick-drying knit with a smooth, anti-abrasion face that handles repeated mat contact. It moves cleanly through transitions without the sticky feel some fabrics pick up under sweat. The shorts and top are built to shed moisture fast between rounds, so you’re not carrying water weight into late work. The overall feel is supportive without restriction, designed to handle friction and keep coverage when the pace spikes.

Care is simple: rinse after training when possible, machine wash cold, and hang dry to protect the fabric’s smooth face. Skip high heat and bleach. This approach preserves stretch and color over heavy use. Within Apollo’s range, Flux is the reliable daily driver—short-sleeve simplicity and quick-dry performance. If you want long-sleeve coverage, a three-piece kit, or bolder graphics, our other sets cover those needs. Keep Flux in steady rotation between hard rounds.
