The Osprey Origin Women’s 5mm winter version uses the same great cut and design as our popular summer wetsuits making it perfect for all water sports and adventures including surfing, kayaking, wakeboarding and kite surfing. This 5/4mm winter wetsuit has fresh blue accents adding colour to the classic black design. A 5/4mm wetsuit means the Osprey Origin has panels of 5mm thick warm insulating rubber, with 4mm panels under the arms, where you need more flexibility and stretch for paddling and surfing.
