BornBound’s new calf sleeve is part of our collaborative project with Nalini that brought the Skärvatten Pro tri suit to our in-line range. This project began as an essential part of the support with give to our sponsored Pro and AG triathletes in the clothing that we supply them and the confirmation that they are in some the fastest clothing products available.  Our tri-suits already give exceptional power savings on the bike, enabling the wearer to either reach higher speeds easier on the bike, or maintain speed with less power to save your legs for the run. These calf sleeves will give you even more aero advantage when combined with the suit. We believe though our stringent aero testing that a combination of our suits and calf sleeves can bring about a 15-20+ watt saving at 40+ kph with most physiques, male and female, when compared to other leading aero suit and sleeve combinations.
