LAVA Pants Special

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.

    New triathlon tool

    These pants are incredible and will go great with my wetsuit top. Truly a game changer for triathletes looking for another option in wetsuits. Great buoyancy and quality product. Will be using these for my April Ironman Woodlands TX race and for the remainder of my tri racing schedule. Middle of the pack swimmer wanting an improvement in open water swimming. These make 2 piece wetsuits legit.

    Great for cold water

    My knees and feet get cold. Swimming in S.F. Bay, I’ve tried wetsuits and vests and really prefer the lava pants. They keep my legs warm without restricting my upper body- no chafing on my arms and neck. I don’t use them all the time, but they really help after a couple weeks out of the water. Great purchase for me!

    Great for training

    The buoyancy that these provide is great for enforcing good body position and it is certainly a nice psychological boost to have a notable chunk of time (artificially) taken off of lap splits. Also, good pool prep for wetsuit legal open water swims without overheating in a full wetsuit.

    Great for training

    I am new to triathlons so I picked up a wetsuit before I knew they should not be used in a pool for training. I picked up lava pants to train in the pool and they have dramatically improved my swimming form (I am a leg sinker). I have also recently learned that swimming in a wetsuit is very different that swimming in regular swim suits. The lava pants help to simulate wetsuit swimming while training without exposing my actual wetsuit to chlorine.
