LAVA Pants

Rated the #1 swim training tool, LAVA PANTS are the secret weapon to making you train smarter and swim faster.  Retire your pull buoy and focus more power on your swim stroke and proper body position.
SPECS - 5 mm premium neoprene on the front and back.  Drawstring.  Ends mid-calf (capri cut).  Backside lower than lava shorts for easier flip-turns.
This "training wetsuit" offers race-level buoyancy and a natural range of motion at every training session, which over time improves technique and pacing while building muscle memory.  Proper body position increases stroke efficiency and adjusts for the proper catch-phase for racing.  Dynamic design makes LAVA Pants comfortable to train in and easy to change into and out of.


The waistband is low-cut, allowing for natural breathing and comfortable flip turns.  As a 3/4-length pant, LAVA Pants are easy to put on in or out of the water, for a quick transition from warm up to workout to cool down. Made for the pool but warm enough for some open water swims, heavy-duty construction ensures that LAVA Pants are a durable training tool for most water conditions.

LAVA PANTS are completely legal under the new rules set by USAT and WTC when wetsuits are legal. LAVA PANTS are a wetsuit and can only be worn in races that permit wetsuits.  They are primarily intended for training, but are quickly showing up on the starting line of many triathlon swims.

This is some of the best triathlon gear for swimming you'll ever find.  Swim faster in a pair of Lava Pants, neoprene swim pants made for swim training and racing.

    Lava pants

    Great product. Floats your hips and legs like a full wetsuit but can be worn in warmer water.
