There are three brands of Buoyancy Shorts on the market today Blue Seventy, Zone3 and Huub launched in 2017. Zone3 first launched their buoyancy short in 2011. Blue Seventy launched their Core Short towards the end of 2015 with a higher quality, smarter looking buoyancy short. The neoprene was made from Aerodrome neoprene - meaning it contained little bubbles of air to aid buoyancy.
Zone3 who had been selling one product until 2016 have responded by introducing three products
Huub have launched a new premium neoprene short called the Sphere in 2017. Huub also launched a kick pant that provides even more buoyancy. Zone3 have responded in 2018 with their own version.
