If you are looking for some buoyancy benefits but don’t want to go down the full buoyancy short route, then the Neoprene Men’s Jammer will tick that box.Made from Yamamoto 1.5mm neoprene with Super-Stretch lining, this technical garment can offer buoyancy, speed through the water and additional warmth.It doesn’t offer as much buoyancy as the 5/3mm thick buoyancy shorts, but are a lot subtler and can be worn under or over swimwear for the whole swim session, whereas Buoyancy Shorts are only intended for particular sets.The shorts are glued and blind stitched for durability. The open cell neoprene is folded and heat bonded on the legs to reduce water entry. Made with a comfortable waistband and drawstring cord for optimum fit.
