LAVA Pants

Size Guide

LAVA PANTS are the secret weapon to making you train smarter and swim faster.  They will be your #1 swim training tool and make you a faster, smoother swimmer. 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 for a snug fit.  Ends mid-calf (capri cut).  

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 work out to cool down. Originally designed for pool swimming but ideal for open water swims as well.  LAVA Pants are a viable training tool for pool and open water swimming.

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 and open-water swim races.

Lava Pants are one of the best swim training investments you can make.

    Great swim aide

    Great float to put legs in position for faster swim times. Not too long in legs, so easy to get in and off.


    Support I needed

    I purchased these to help me with my pool swim. Took 10 seconds off my 100 right away. I’m am still slow…but a faster slow now. I have pretty thick thighs and glutes and decided to get a large at my smaller height. Fits snug like my wetsuit. Highly recommend.

    Excellent so far!

    Great buy! I have used my wetsuit for 2 weeks now with great results. I am able to focus on my stroke and breathing. I am waist 32 and bought Medium. A bit tight when putting it on but loosens a bit while in the water. I totally recommend it.

    Shorts are great for paralyzed swimming

    These shorts allow me to swim. I am a T12 paraplegic and without them my lower half drags behind me in the water. Not only that, but with other flotation devices I am pulled too high up in the water, whereas these shorts provide the perfect amount of buoyancy. They also provide a snug fit around my legs which helps relax my muscle spasms, making it exponentially easier to swim.
