Lafuma X 650 Pro Sleeping Bag: 40 Degree Synthetic

As far as a lightweight warm weather sleeping bag, this Lafuma x650 Pro is great! Hardly adds any weight or takes up any space in your pack. Construction seems solid although I have not had mine a full season. I have slept in it when the temps dropped into the mid 40's and was comfortable with just thermal underwear and a sleeping pad out in the open. I would not want to be caught in a chilly early spring or late autumn night with just this bag but for the price, the quality construction, compressing stuff sack, weight, and stuff size, this is a quality purchase that I would recommend to friends.

I chose this bag to include in my UL summer base pack. It's super light, packs really small (actually comes with a pretty useable compression sack), and while it's light, seems durable enough to stand up to some abuse and not complain too much. I paired mine with a silk mummy liner and tested it out in my backyard on a 33 degree night and was comfortable enough that I never woke up due to the cold, and there didn't seem any cold spots. For summer/autumn camping, this bag can't be beat. Footbox is spacious. Zippers don't seem like they'll have snagging issues. The only problem I had with this bag is that there's a small pocket on the inside that uses a Velcro closure that might chafe your mummy liner the wrong way. I took that Velcro piece out with a stitch remover tool, problem solved. Lafuma did really well designing this bag.

Great bag, super light, super compact, and comfortable all the way down to 40. I've used this bag several times in early spring at virginia beach, where the temps at night were sometimes down below 40, and with a thermal top and bottoms, I was totally comfortable. Great bag for summer camping/backpacking.
