⚡ At a Glance
- • Wearing Comfort: Lightweight stretch fabric with flat-locked seams and half-sleeve cut
- • Best for: Gym-goers wanting increased sweat, waist shaping and core support
- • Not ideal for: Those preferring loose, non-compressive casual tops
Form-fitting sauna shirt with a heat-reflective blue inner layer and elasticated compression. Lightweight construction and flat-locked seams maintain outer dryness while encouraging internal perspiration.
Faster Sweat and Targeted Weight Cutting – Thanks to a heat-reflective inner layer
Blue inner heat-reflective fabric, certified REACH and OEKO-TEX 100, traps body heat close to the skin. Elasticated compression increases local temperature and encourages higher perspiration around the abdomen, lower back and chest.
Higher sweat output during cardio and circuit sessions helps accelerate temporary water-weight loss and makes weight-cutting phases more efficient.
Improved Core Stability During Training – With elasticated compression design
Compression panels apply even pressure across the torso while extended underarm sections preserve mobility. The half-sleeve construction balances support with freedom of movement for lifts and compound exercises.
Better core and lower-back stabilisation during strength training, helping to maintain posture and reduce unwanted movement under load.
Discreet Everyday Wearability – With thin outer fabric and flat-locked seams
Water-resistant outer layer and ultra-light stretch fabric are engineered to keep external clothing dry. Flat-locked seams reduce bulk and minimise chafing where the shirt meets the skin.
Comfortable to wear under regular clothes or on its own, suitable for running, gym sessions and longer wear without obvious bunching or abrasion.
