These Didriksons Biggles Zip Mittens are a great accessory for the rest of the Didriksons range. The Zip version here features a zip along the mitten which allows them to be opened wide for easy putting on, especially with small delicate hands. Windproof, very warm and water resistant. The internal lining is a very soft fleece. With an adjustable and elasticated wrist strap, they can be adjusted to achieve a secure yet comfortable fit.
