Berghaus Extrem Duvet 2011

The Berghaus Extrem Duvet is almost the ideal duvet for really cold winter nights on the hills. It comes with good-quality down and is very warm, unlike some of the lighter jackets here. That added insulation does mean this is a little heavier than some at 708g, but I’d rather go for maximum warmth than minimal weight in winter. The outer is Pertex, but not the new superlight 10 denier version, so it feels pretty robust. The jacket has the usual features of two zipped pockets and a front zip with baffle behind. But you also get Velcro-adjustable cuffs and a hood with lots of good adjustment that allows it to fit very closely and move very easily with the head. There’s a small brushed fleece chinguard too for added comfort, and generally this feels ideal for sitting around a winter campsite or watching a sunset from a winter Munro.  But the Berghaus Extrem Duvet’s hood has a huge wired peak, and while I normally love such features this one just obscures vision so much that I had to flip it vertically to get it out of the way. The hood is not removable either, which some may find annoying for off-the-hill use. The main problem though is that there are lower-priced duvets that offer similar performance.

The Berghaus Extrem Duvet is a great duvet for cold winter mountain use, but you can get similar performance at lower prices.
