NW_Nativewrote a review of Mountain Hardwear Ultralamina 15 Women's Sleeping Bag: 15 Degree Synthetic on July 7, 2008
I'm a three season backpacker and have used this sleeping bag for two full seasons. This is a great bag. It's on the higher end of pricing for a synthetic bag but it's warmer than some down bags that I've been in and just as comfortable. I haven't gone winter camping but would have no reservations with taking this bag.
As others have stated, the half zips are great for reading, cooking, venting, etc. but if you like to stick your feet out at night then you may feel claustrophobic in this bag.
-Compresses into SMALL stuff sack which is great for backpackers
-More shoulder girth compared to majority of women's bags which helps to not feel so constrained
-Minimal snaging from zipper! Extra lining along zipper make it easy to zip/unzip from inside without snagging preventing tearing
-Maintains loft well even after a winter in the storage sack
-Open foot box to not make your feet and legs feels so cramped
Cons: -Higher price. Find it on sale.
-Non full zip (if you like the full length)
-No sleeping pad straps
-No internal pocket to make a pillow (I'm really just digging for cons at this point)
Bottom Line: You can't go wrong with this bag. If you can find it on sale get it. You'll be hard pressed to find another synthetic bag that will keep you this warm and comfortable.
