The Polycotton tents are the top range of tents that we stock. Produced from Outwell the Harrier XL and Harrier L are sure to be as popular for 2015 aswell as the new Euphoria 600 from Vango. They are a mixture of Polyester and cotton and when combined produce a fabulous breathable material which reacts to its environment. They are completely waterproof and are designed to retain the heat in colder environments while still keeping you cooler when used in warmer climates.
