CHECK THE SIZE CHART (in the image section above) The HUUB Alpha Open Water Swimming wetsuit has been designed to offer fantastic flexibility whilst having the buoyancy required to give you the most comfortable swimming position. The days of adding the thickest neoprene panels to the chest and legs have long gone because we know that by adding more buoyancy to the legs and less to the chest we can reduce the frontal drag of the wetsuit, and put you in a better swim position. An addition to our range of award-winning suits, created with HUUBs renowned attention to detail and scientific knowledge, wrapped in a package of performance and stunning value. And for the first time, we have managed to introduce our new highly flexible flat-lock construction method found on thinner material wetsuits, delivering a great feeling wetsuit. Alpha is the ideal first-timers wetsuit. Features: 2:3 buoyancy combination - for improved body position and reduced drag. Scientifically researched neoprene thickness combination. 1.5mm under arm thickness - for maximum flexibility. Glide skin neoprene - for reduced surface drag. Specific panel placements - for flexibility and efficiency. Speed cut ankle & smooth skin cuffs - for ease of exit. Flatlock construction.
