Marmot 40°F Wind River Sleeping Bag - 600 Fill Power Down, Semi-Rectangular

I don't like mummy bags, and this bag is just wide enough to give me room to breath. When I tried it out last winter, I added a lightweight (1.5 lb.) technical blanket as the temps dropped into the teens, but I stayed comfortable all night. Most of my camping is with temps in the 40's at night, and I find this bag a little warm as it gets above that. But it zips completely open and makes a nice blanket in warmer weather. As always, your choice in sleeping pads makes a major difference in keeping warm, as more heat conducts through the bottom than radiates out of the top. With a good pad, this bag's 40 degree rating is conservative. With a poor pad, or none at all... With a decent compression bag it packs very small, and if you're likely to get wet make sure the compression bag is waterproof, as down does not dry easily.

Took the bag on a week long backpack trip in the Beartooth Mts in Montana. It froze at night and found I needed long underwear to be comfortable. Stuff sack was large enough to hold therm-a-rest, long underwear and bag. Loved the drawcord! Will never buy another one without a drawcord.

It's hard to find a quality lightweight sleeping bag that fits Texas camping conditions. We rarely have the colder nights and many bags are unsuitable for milder nights. I am enjoying it!

Weight online says 1 lb. 15 oz., but on the tag of the bag it clearly states 2 lb 7oz. Which is still ok, but not as exciting.

I use the sleeping bag when we travel by boat. It's light, doesn't take up much room and comfortable.
