Women’s BASIC long-sleeve wetsuit in black with green accents, angled front view, featuring Rocket Science Sports branding.

A step up from your first wetsuit. The RSS BASIC is built for triathletes ready for more — more flexibility, more comfort, more performance in the water.

Targeted construction delivers exactly what you need where you need it: a 5mm core for maximum buoyancy, 2mm shoulders and sleeves for unrestricted stroke recovery, 3mm lower legs that stay flexible through your kick. Real performance gains over an entry-level suit, without jumping straight to the premium tier.

I've got: 5mm thickness through the core, hips, and upper legs delivers maximum lift — keeping you in the most efficient swim position from the first stroke.

Flexibility: 2mm shoulders, sleeves, and crotch panels give full range of motion for unrestricted stroke recovery and natural movement.

Warmth: 3mm lower legs provide cold-water comfort without sacrificing kick flexibility.

Fit: Anatomical cut for triathletes ready to upgrade from entry-level — snug, supportive, made to move with you.

Designed for: Triathletes stepping up from their first wetsuit, open water swimmers seeking better performance, and athletes training for serious race-day results. Marketplace

Still not sure of your size?

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.
