    WHAT?!!?! – Out freaking standing sleeping bag. The weight is insanely light and it might actually be too warm.

  2. Allen

    A quality winter bag – I am on a long distance motorcycle trip from Alaska to Patagonia. The trip also involves a lot of alpine climbing so the weather swings on the trip are quite dramatic.

    New favorite bag – I got to take the Oberon for a “test sleep” with Thermarest in January, and I was thoroughly impressed. The weather was damp.

  4. Robert

    Excellent light wight winter bag! – The Oberon sleeping bag is extremely light and compact to be so warm! It packs and weights as a three-season bag, but works fine in winter! Last winter I used it in the Norwegian mountains.

    Thermarest Oberon Sleeping Bag Review – I have started winter camping and was looking for a sleeping bag that would allow me to camp out in temperatures under 32 F ( 0 °C) as well as double as a sleeping bag I could use in the spring,.

  6. Erin

    Excellent winter bag for ski trips! – I absolutely loved using this sleeping bag on a series of ski trips in different backcountry huts as well as snow camping! It packed small in a stuff sack and was light weight carrying it on.

  7. Mike

    Best winter bag out there – This is bag is the bees knees. It is already as light as my 15 degree bag I use at altitude in the summer and packs up pretty dang small.

  8. Matt

    Kept me warm during a winter storm at 10,000 feet – This bag is very light, easily compressible, and quite warm. I was at Camp Muir in early June when a very wintery storm rolled in with 10 degree temperatures, 40+ mph wind and lots of snow.

  9. Ethan

    Excellent winter bag with 3-season weight! – I recently used this bag during an ascent of Mt. Baker in Northern Washington and I loved it.
