Marmot Ama Dablam 2011

The Marmot Ama Dablam is a lighter-weight duvet than those at a lower price but you still get a hood and a reasonable amount of insulation. The jacket has top-quality down and a polyester shell that resists light rain and is much softer than the nylon options. The Ama Dablam has the usual zipped hip pockets and a good anti-snag zip baffle behind the main zip. You do get an additional chest pocket though and also Velcro-adjustable cuffs. There’s a nice patch of soft brushed fleece to protect the chin from the zip too. Most importantly for any serious cold weather use you get a hood. This has a volume adjuster, which results in this hood fitting particularly well and moving well with the head. This is not as warm as some lower-priced options, but it is okay for milder winter conditions. But this particular fabric does feel a little softer and less durable than heavier nylon duvets, although polyester is less affected by UV so in the long term there are benefits. The hood cannot be removed so this is not so good if you don’t want it on all the time. The main problem though is that this is not ideal for wearing on a summit sunset in winter as it is not as warm as some others.

The Marmot Ama Dablam is a useful hooded duvet for year-round additional insulation, but others are better for the coldest winter days.
