Great Bag
January 25, 2011

This bag packs very very small. It is very light weight as well. Great for long backpacking trips where weight is very important. Being that is 32 deg, its great for summer and warmer seasons. It seems to hold true to its warmth rating. Warmth can be improved with a sleeping back protector/cover for colder nights. I would recommend this bag to friends and family. Great product, it also comes with a stow back and stuff sack. I like the dual short zipper design.

Pros: Great design, Build quality, Ease of use

Warm, light and compactible. Great on 12-day backpacking trek.
August 09, 2009

I purchased this bag for my teenage son to take on a 12-day 70-mile backpacking trip at Philmont in New Mexico (late July to early Aug). Since this was a Boy Scouts' trek, down sleeping bags were not permitted for scouts. We chose this synthetic filled bag because of its lightweight and compactness for backpacking. This bag worked very well on the trip. It was warm enough for the weather that varied over the 2 weeks, including an unexpected ice storm. The bag comes with a compression sack that compacts the bag to about the size of a sack of flour. This allowed the bag to be carried within the backpack where it could be kept dry during Philmont's "monsoon" season.

Great for backpacking
January 17, 2009

I have used the Ultralamina 32 on a couple 3-5 day backpacking trips, and I am totally satisfied with it. I really haven't found another bag that combines its features for the same price. I bought it because it is lightweight (less than 2 lb.) and packs up very small (6 x 11 inches)...perfect for an extended trip. My wife gave this bag her stamp of approval at 40 degrees, which tells me any normal person would be comfortable at 32 degrees. I liked this bag enough to buy a second one.

Great bag, light and compact, strong design, not warm enough
July 27, 2009

I purchased a set of these bags for use in Northeast early summer camping, where temps were reaching the mid to low 40s at night. We didn't find the bags to be warm enough (both women), despite the 32 degree rating. All other features of the bag were wonderful; loft, compressibility, comfort of the materials (especially the hood) and durability. I've returned this set, and purchased the Ultralamina with a 15 degree rating as replacements.

Good for the money
October 01, 2011

I like this bag because it packs small (7x10) and is light for a synthetic bag. I gave it 4 stars because it is more like a 40 degree bag and the fit is rather tight. It is a tighter fit than my 0 degree Banshee. (for the record, I'm 5-9, 175 lbs)

last minute purchase
July 02, 2011

Was looking to shave weight for my first multiday BP trip on the West coast Trail. Saw the reviews for this bag and rolled the dice. It performed great. It was just a tad short for my 6ft but not uncomfortable. The neck draw cord also tends to slip open as it has a funky kind of securing device. I plan to replace the one provided with an aftermarket one similar to the hood draw. We woke up one morning to some tent leakage that dripped right on me but felt nothing inside the bag. Most nights were in the low 50s or high 40s and I was very comfortable with minimal sleep wear.

Pros: Performance, Ease of use, Great value

Great light weight bag
January 30, 2012

I've been looking for a nice lightweight bag that wouldn't break the bank, and this bag fits the bill nicely. I went for the long version, which was a wise choice. At 6'1, there's no way that I would have comfortably fit into the standard length bag, but the long bag leaves a small bit of wiggle room at the feet. It's warm without being restrictive (good for us side sleepers), and comes with a loose storage bag and a small compression sack that is roughly the size of a small peanut butter jar.

Pros: Great design, Build quality, Ease of use, Great value, Performance
