Maximizing performance and comfort The Rab Power Stretch Pro can either be worn as a heavyweight baselayer or a insulating midlayer. It has an excellent warmth to weight ratio making it an obvious choice for long trips and cold expeditions. Designed using Polartec Power Stretch Pro, this midlayer has four-way stretch giving you complete freedom to move, whilst the fast wicking fabric works hard to both insulate and manage moisture.
