Rocket Science Sports VENOM long-sleeve men’s wetsuit for triathlon and open-water performance

The pinnacle of open water performance. The RSS Venom is engineered for elite athletes who demand every possible advantage on race day — combining advanced materials, precision fit, and hydrodynamic design at the highest level.

Triple-layer composite construction through the core, thighs, and legs delivers maximum buoyancy with greater flexibility than a solid panel. Strategic 2mm panels reinforce high-stress zones. Ultra-thin 0.3mm forearm panels release water faster on every pull. 2.5mm collar and back torso provide structural support. This is the most refined construction in the RSS range — built for those who want the very best.

Buoyancy: Triple-layer 1+3+1mm construction through the core, thighs, and legs delivers 5mm of total thickness with greater flexibility than a solid panel.

Flexibility: 1.5mm mobility panels through the sleeves, shoulders, and underarms — unrestricted stroke mechanics for elite-level performance.

Speed: 0.3mm forearm panels engineered for fast water release on every pull — minimal drag through the catch and pull phase.

Reinforcement: Strategic 2mm panels at high-stress zones — knees, cuffs, lumbar, and torso strips for targeted support.

Designed for: Elite and pro-level triathletes, high-performance open water swimmers, and athletes who want the very best wetsuit in the RSS range.

Rinse in fresh water after every use. Hang dry inside-out, away from direct sunlight. Never machine wash, tumble dry, or store wet.

Use a wetsuit-specific shampoo or conditioner once a month to keep the neoprene supple. Avoid contact with petroleum-based products like sunscreen or insect repellent before swimming.

Stored properly, your wetsuit will last seasons.
