Swim Gear
Built In
The Water.
Swimming humbles everyone. You can be fit, train hard, and still feel like you're getting nowhere. The right gear changes that.
The Full Range
Three products. One goal. Train smarter, feel the water, stop wasting laps.
Why It Works.
Three reasons swimmers choose BlackLine over generic gear.
Feel exactly what your catch is doing. The paddles reveal bad mechanics immediately so you can fix them in the same session.
Not oversized power paddles. Technique paddles. Built to add resistance without overloading joints so you can train every day.
Designed by Nolan and Kilian Carrel — competitive international swimmers who use this gear every single training session.
Swimming Isn't About Power.
It's About Feel.
Most gear lets you cheat through bad habits. The Velocite doesn't. Clear design with red edges gives instant tactile feedback on every catch.
- Technique first — not a power paddle
- Adjustable straps — secure fit on any hand
- Shoulder-safe design — train every day
- Lightweight & durable — daily training grade
Remove Breathing.
Fix the Stroke.
When you're fighting for air, your head moves, your hips drop, your stroke falls apart. The snorkel removes that variable entirely.
- Front-mounted — full field of view
- Slim tube — mild CO2 resistance training
- Locks head position mid-stroke
- Black or White — one size fits all
