Apollo Undertow Rash Guard Set — No-Gi Rash Guard & Spats Set

Choosing the rashguard-kit

The Undertow is for women who train year-round and don’t stay indoors. It handles conditioning days, no-gi drilling, and mixed sessions that move from mats to water. Run the long sleeve for grip-heavy rounds or under a gi when you want more coverage. Use the full three-piece set for surf, pool sprints, or travel workouts, then dry fast and keep moving. Clean coverage without bulk, built for work, not beach posing.

Expect a close, training-first fit typical of rash guards. Choose your regular top size for a secure feel that won’t slide under a gi. If you prefer a little ease for conditioning or casual swim, size up. Between sizes, use bust for the vest top and chest/shoulder for the long sleeve; use hip for the bottoms. Longer torsos or broader shoulders may appreciate the next size up for extra length and mobility.

This set uses a quick-dry polyamide knit that balances coverage with freedom of movement. The long-sleeve rash guard gives full-arm protection for mat rounds and wind on open water. The vest-style swim top uses fixed straps for dependable hold during sprints and entries, and the coordinating bottoms keep the kit streamlined. The fabric sheds water efficiently and stays comfortable whether you’re sprawled out in drills or paddling back for the next rep.

Rinse after salt or chlorinated sessions, then cold wash and hang dry. Skip heat and fabric softeners to preserve the knit. Avoid rough decks and concrete to reduce abrasion. Among our rash guard sets, Undertow is the crossover option: a versatile three-piece that covers both mats and water without swapping gear. If your week mixes no-gi drills with surf or pool work, this is the set that keeps pace without forcing a change of kit.
