Sea to Summit Men's Traverse III Synthetic 15°F/-10°C Sleeping Bag

[This review was collected as part of a promotion.] I bought the tall and wide version because I like my space. It worked well in summer and also on our latest camping trip with temps dropping to -3 celsius over night. I don't go much colder. For the lower temps i use a reactor xtreme liner and will get myself a pair of down booties. My feet are cold at the best of times and the down jacket around my toes kept slipping away.

[This review was collected as part of a promotion.] The features on this bag make it the best synthetic sleeping bag I’ve ever tried. It’s also warmer than I expected. I’m a very cold sleeper.

I have been using this sleeping bag for a camping trip in Switzerland for half month in September. There is occasional rain but the bag can still keep warm. The lowest temperature at night I tried was 2 degree celcius. The bag and I performed well because I also wore enough clothes and sock when sleeping outdoor. Overall, I am very satisfied.

[This review was collected as part of a promotion.] Only used the bag once so far in 45° weather but slept comfortably with zipper open for venting. The long fit my 6’2” frame with room to move around.

[This review was collected as part of a promotion.] I called out in 32 degree weather and slept like a baby.

My husband and I purchased these sleeping bags. My husband got the longer one because he is 6'3". They were very comfortable and we like the extra room for the feet. The material does stick to your skin a bit so I am going to order some liners. They packed up easy in their bags and fit perfectly into our packs. We have not used them yet for colder weather yet.

I’ve only had it out on a 45* night so far but within 10 minutes of getting into it, and several times throughout the night, I had to vent it because it got to be too warm. That’s not the bag’s fault; all the bags I’ve had until now are 10-15 years old so I’m used to having to squeeze every bit of insulation out of them that is possible. What I should have done is open up the zipper and perhaps every use it as a blanket instead in warmer weather like I had. The construction of the bag was very well thought-out; especially the zipper design that pairs with the women’s bags and the small loops for attaching cord (I used elastic shock cord) to keep a sleeping mat from sliding out from underneath you are a nice touch.

First of all this picture is not true the sleeping bag is not smaller than the water bottle. And it’s heavier than it looks. If your looking for light weight compact, this is not for you.
