Perform Fiber Sleeping Bag: 14F Synthetic - Women's

Amazing sleeping bag!!! Love all the features! Cords: 1 for neck and 1 for face to improve air tightness! I love the front zipper, at first hard to get used to but rapidly you understand how to use it properly. I love having something on me when I sleep, but sometime it's just too hot. So unzipping the front zipper from the bottom allows a fresh breeze to come in! I always take women sleeping bags instead of men's because they have more insulation in the feet...I'm a cold toes sleeper.

Good bag but a bit bulky.

This bag is well made with good materials and durable. The synthetic insulation at this temp makes it a bit bigger than I would like in a backpack and the included compression sack struggles a bit to contain the size. If that is not an issue it is very nice otherwise.

Much narrower than I expected but the bag material is amazing.

Warm but a little roomy

The bag performed as expected and was relatively warm also, there are a lot of nice thoughtful touches (cell phone picket, pseudo-shrink sack, eye mask, ear plugs, etc.). The center zip is a great feature as it removed the left-handed or right-handed ordeal and, if you sleep on your back or side the zipper isn't really noticed. The downside is that it is a little roomy and a little chilly. I bought the small for my girlfriend and it was pretty roomy in the foot box and legs. Fully understanding different body dimensions fill the bag differently but still, it seems a bit roomy. We were canoe camping in late Sept. and she had to layer up to keep warm when temperatures ranged from -1 to +6 at night which is well within the range of comfort for the bag. Overall a nice bag with lots of features however, the -10 rating might be a little generous.
