Created by Tom and Phil Beahon, both ex-professional sportsmen in football and cricket respectively, premium sportswear brand Castore is designed with athletic performance in mind. All the materials and fabrics used in Castore garments are unique to the brand, and its Proteas collection has been created specifically for ‘warmth without weight’, for optimal training in cold temperatures. Made up of a selection of waterproof jackets, lightweight tees and sweat-wicking shorts, key technical features include protective waterproof layers and special breathable linings that allow excess heat and moisture to pass over the fabric, making the gear fully air-permeable.
