Marmot Wave III 2009

The Wave III 3-season synthetic sleeping bag 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 good water resistance. The bag 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. But it is very heavy so although it can be squashed down it’s not the best for backpacking. The top half of the hood has an excess of fabric and bunches when tightened in. The internal stitched seams are quite noticeable against the skin.

Verdict: Weight is a drawback but compared to other 3-season synthetic sleeping bags of this price the Marmot Wave III offers a good compromise between the temperature rating and features for general 3-season camping. It won ‘Best Value’ in our test.
