Lafuma Warm'n Light 600 Sleeping Bag: 40 Degree Down - 2010 BCS

I love my sleeping bag! So light weight and barely takes up any space in packing. I take it with my hammock and spend most of the summer sleeping in the woods by the river.

I got a really good deal on this bag to supplement a 3 lb Marmot bag. It is what it is- a very light, very thin down bag. It's EN rated, so look at that NOT the 40 degree. It's warm enough for me for the summer, and it compresses to the size of a 1 L Nalgene bottle, perhaps even a bit shorter. I'm quite overweight but fit in it fine- on those warm summer nights it does the trick. Overall, I'm pleased with the bag and am very happy that it allows me to go light on warm summer trips.

Only used the bag two nights and i'm happy. I sold my car camping gear and upgraded to actual backpacking grade gear. Super psyched. The bag is super light and tiny when compressed, and the down makes a big difference. I could see this bag being a bit too chilly for early spring/late fall, but with my russian heritage (i'm always exuding tons of heat and almost always sweat in my bag), i have no concern for it's ability to keep me warm. I was nice and toasty on an early summer eve. If you're a generally warm person, then i highly reccomend this bag...i mean, it packs just as small as my sleeping pad (if not smaller).

This bag is very thin. Also the stuff sack it comes with rates it more of a 50degree bag(for comfort). For a summer bag that is light and small in the pack this is a solid buy. If you get it on SAC, it's a steal.

What a small bag - maybe 3/4 of a Nalgene and light as can be. The quality is very good, with nice features (glowing zip pulls, interior pocket, two draw pulls for the hood and chin side of the opening). It comes with a nice (maybe fragile) stuff sack and a storage bag for your closet a home.

The 40 degree rating is quite a stretch so be warned -- even at 45-50 degrees (Aspen in July) I was shivering. I noted cold spots at the shoulders and trunk area in particular and along the zipper (no baffle) even with heavy long underwear bottoms, a fleece, silk top and hat. The down layer is thin -- you can feel areas where the inner and outer nylon layers are in direct contact.

I would highly recommend this for a summer-weight ultra-light and ultra-small bag but don't push the rating - stick with 55+ if you can for a more comfortable night.

I'll likely try to push this bag a little further with a liner or golight quilt but this defeats the size/weight advantage. I'm also realizing that I'm an obligate side-sleeper and maybe happier with a quilt system or big agnes...we'll see.

i admit that i'm a cold sleeper, but when it's 55 and i'm so cold i have to pull a tarp over me despite a liner, long underwear, fleece and hat i'm not going to be satisfied. especially considering that the golite 20* quilt is the same weight. i also found it to be super restrictive in the knees and overly roomy in the torso, too narrow if you move your legs much in your sleep, and too big in the torso to retain enough heat.

i did use it in mexico in the summer (probably in the upper 60s at night) and was fine there...
