Marmot Wave IV (2012)

The Marmot Wave IV is a well-proven sleeping bag that manages to keep campers warm in winter for £100. To hit this price the bag has not been made to be as warm as others in our test, so it only has a temperature rating of -10 deg C.
The benefit of shaving a little off the temperature rating is that the weight, packed size and price are lower compared to warmer synthetic bags. The bag features a full-length side zip for venting and a wide shoulder baffle for preventing warm air from escaping. The bag is lined with polyester, with the foot, shoulder baffle and hood benefiting from a brushed treatment to give a much more comfortable and warmer sensation. There is also a pouch for stashing a heater pad in the footbox if you want some extra warmth. If your budget is £100 then the Marmot Wave IV is an outstanding bag, but for extra cash you do get extra warmth.
