Mammut Stratus Hooded

This duvet jacket is very warm; synthetic insulation; fixed hood; zipped hip pockets; useful external chest pocket; elasticated cuffs with thump loops; superb movement in sleeve. But 866g is a bit heavy; the basic design lacks some of the advantages of other garments.

Verdict: Buy it if you want a good, low-priced synthetic duvet with a hood that is very warm and ideal for most UK mountain conditions.
