Aerodynamism is a key factor in bike performance, that's why reducing the air resistance is essential. The Kiwami's R&D team improved the Prima LD AERO Trisuit by selecting a new fabric, making the trisuit even more aerodynamic by a snugg but comfortable fitting. Kiwami has redefined the strengths of this model: very flexible short sleeves that cover the shoulders and the arms up to the elbows, ergonomic pockets for refueling and Kiwami's long-distance chamois. The PRIMA 2 LD AERO, likes its predecessor, can be worn under a neoprene suit or used alone in case of non-wetsuit swims.
