Western MountaineeringEverLite 45 Degree Down Sleeping Bag

I'll start by saying we own over a dozen Western Mountaineering sleeping bags and have been using them extensively for years. They are as good as it gets. This bag is no exception. This sewn through (not baffled) bag is rated to 45F. I haven't had a chance to test that rating yet. I do however own the MityLite which is rated to 40F and have slept comfortably many times down to the low 20s wearing only a base layer, down socks and down balaclava. The 6'6" version is very spacious and comfortable for this 5'10" 160lbs. side sleeper. The bag packs easily, lofts immediately upon retrieval and boasts the finest materials and workmanship on the planet. Make sure you have adequate insulation underneath, and this bag will treat you to some incredibly comfortable warm nocturnal outdoor bliss for decades to come.

This is a phenomenal sleeping bag, the best summer weight bag I’ve ever used. It is versatile - unzips to make a comfortable blanket for warm nights and cinches up well for cool nights. The temperature rating is spot on, easily good down to 45 degrees. Wearing long underwear and a stocking cap I was perfectly comfortable on a 40 degree night, though I tend to sleep a little warm. It is exceptionally light weight and packs small, but is made of high quality materials. I have used the bag 25 nights and expect I will be using it for many years to come.
