La Pochette Sweat Bag (£35) makes a thoughtful gift for anyone who loves going to fitness classes before or after work. Made from recycled plastic bottles, the antibacterial and water-resistant kit bag is a chic and hygienic way of storing damp workout clothes on the go — a great alternative to using the single use plastic bags offered at many boutique fitness studios. They're machine washable and come in a variety of hues.
