LAVA Shorts


LAVA SHORTS are a must for swimmers and triathletes of all levels. LAVA Shorts lift your hips to simulate the same body position of a wetsuit. LAVA Shorts create proper technique and allow you to focus on speed.  This is some of the best triathlon gear for swimming you'll ever find.

SPECS - 5 mm premium neoprene on the front and back.  Drawstring.  Ends just above knee.

BEGINNERS - Beginners will love the extra and immediate buoyancy that the lava shorts give you the second you put them on.  If you are truly a hip-dragger then consider our LAVA PANTS (below the knee) which will provide slightly more buoyancy in your lower body.

INTERMEDIATE - LAVA SHORTS are designed for shorter speed and technique sets as well as cool-down.  The shorts are above the knee thereby allowing for natural flip turns.  For long swim sets, or for recovery swims, consider the LAVA PANTS which provide additional buoyancy. 

ADVANCED - LAVA SHORTS can be used for both speed and recovery swims. For speed sets, LAVA Shorts will allow you to train at faster interval paces. For recovery sets, you will be able to focus on correct swimming form without exerting too much energy.

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. Dynamic design makes LAVA Shorts comfortable to train in, do flip-turns, and easy to change into and out of. The waistband is low-cut in the front and rides higher in the back, allowing for natural breathing and comfortable flip turns without concern of losing your suit. LAVA Shorts 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 Shorts are a durable training tool for most water conditions.

LAVA SHORTS are completely legal under the new rules set by USAT and WTC when wetsuits are legal. LAVA SHORTS are a wetsuit and can only be worn in races that permit wetsuits. Always check with the race director prior to using the LAVA SHORTS in competition.

WARNING - 1) these are addictive; 2) rinse well because chlorine will decrease their life; and 3) don't let them dry in the heat and inside out.

    Great for a beginner

    As a 75 year old male that is finally learning to swim, the lava short is a wonderful assist. I�m slowly building my endurance and hopefully will be able to do a sprint triathlon early next year.

    Great training aid

    This is a great way to simulate a wetsuit swim while training in the pool, and it's much easier to focus on my stroke when I don't have to worry about my kick.

    Just what I needed

    I needed help with my buoyancy during training. A pull buoy provides buoyancy, but doesn't allow me normal use of my legs to kick. These Lava Shorts are just what I needed. They are a little less buoyant than the pull buoy and are helping to develop muscle memory regarding what the correct swimming form feels like. This transfers to my swimming without the Lava Shorts. I would buy these again.
