Marmot Wave III 2011

A really good product for the price, the Marmot Wave III is pretty much all you could want from a 3-season synthetic sleeping bag. It’s a reasonable weight and the cut manages a clever balance between spacious comfort and snug warmth. The outer shell is highly water-resistant yet soft, whereas inside you get a luxurious, velvety scrim in the head and foot areas. Needless to say, the two-way, full-length zip is great and snag-free, and there’s a decent baffle to protect against cold spots. The hood, which is definitely on the large side, is well enough designed to feel comfortable when pulled tight. You also get a great shoulder baffle and more insulation around the chest area for warmth, plus a large internal pocket. But although the Marmot Wave III’s hood is well-cut, it’s hard to pull the drawcords tight because of the insulation around them – and this leads to a small degree of bunching. Also, I think I’d feel quite cold if I was sleeping at the -7.4 deg C comfort rating temperature; and I broke one of the straps when compressing it.

The Marmot Wave III is a great-value sleeping bag with everything you need for comfortable 3-season camping, but a stronger stuffsack is needed, and it may not feel quite as warm as the rating suggests. Still, we’d recommend it.
