Heat retaining second skin, the base layer top has been constructed using seamless technology to maximise comfort when being worn. The superior construction allows perspiration to evaporate away from the body to ensure body heat is retained and to maintain a core body temperature.
The insulation pieces work by trapping small pockets of warm air which block body heat from escaping, combined with a layering system ensures ultimate temperature stability with no effort. Each insulation piece can also be worn separately when off the bike for maximum versatility. As your performance needs change, simply take one insulation piece out and swap it for another to maintain optimal performance and comfort.
