The Wave 3 has a long, slim-fitting mummy shape, with a roomy, well-shaped foot box. The full length two way zip runs smoothly and mostly snag free. The hood and substantial shoulder baffle are adjusted by an easily identifiable mix of tape and bungee cords. It has a large internal pocket for keeping useful kit handy. The inner fabric is soft against the skin, and the bag feels instantly warm when you climb in. The outer fabric is tough and has a good temperature rating of -5, and it compresses down quite well so this means you can fit it into your rucksack with reasonable ease.
Verdict:- Weight is a drawback but compared to other bags of this price it offers a good compromise between the temperature rating and features for general 3-season camping.
