Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

This bag is sweet. I slept in this bag for 4 nights at Zion and it performed very well. It kept me warm when the temp dropped below 50 and its very comfortable. I sleep on my stomach mostly and this bag stretches enough to let me do that. I woke up one night completely sweaty and got out of the bag and slept on top of it for an hour and in that time the inside had dried completely. I'm 5' 8" and this sack fits me with a little room to spare. Oh and its incredibly light. I would definitely recommend this bag to anyone.

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

This bag is great for warm weather trips. I like the small pack size of this bag. I like having two zippers on the left and right size. The zipper's don't go down all the way to the bottom of the bag which works great for me. With my old sleeping bag I would work the zipper down to my butt in the course of the night which cause me to wake up from being to cold since I wasn't covered. I have not worked down the zippers while rolling over while sleeping in this bag. This bag fit me great. I'm 5'10" and wear a 44 regular jacket. Had room to move up in down in the bag and in the shoulders. Hard to say how much room I had more room vertically than horizontally. I didn't feel tied up or trapped and the bag rolled with me. My conjecture is if you are approaching 6' tall and have broader shoulders this bag might be to tight on you. The temperature rating is really accurate. During my last trip to BWCA the temps dip into the low 40's. The first night I did get cold wearing underwear. The second night wore pajamas & long sleeve t-shirt and I was warm. Zippers don't get stuck because of hard material around the zipper. I was able to put my camping pillow in the hood and was able to roll over without rotating inside of the sleeping bad. It comes with a stuff sack and storage stack. No extra work is needed to get the bag into the stuff sack. The inside nylon is softer than the outside nylon not by much but you can tell there is a difference in material. This summer has been really cool so I have not slept in this bag when the temp are really high. The range of temps for me has been mid 70 to the low 40. I'm really happy with this gift. I'm a fair weather camper so once the temp drop below 40 I'm packing up. This is a great summer bag. I'll see how it keeps me warm in the fall, but looking to bring some fleece gear just in case.

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

This back is so light and compressible it lets me stretch a weekend pack into almost a week. I always use a liner with my bags so that I don't have to wash them as often and I am an admittedly warm sleeper but I have slept soundly through the night when I know the temperature has gotten into the high 20's. The duel side zippers are an amazing feature when you need to make breakfast in the morning but it is still too cold to be out of your bag. I was hesitant about not being able to vent my feet in this bag but I have never had an issue with being too warm when I had both side zippers opened all the way. I have had the bag for almost a year and after almost 50 nights of use and a few washes it still looks like new with all of the insulating material right where it needs to be. Bottom line is that this bag is perfect for the weight conscious backpacker who doesn't want to give up the nice features or who might encounter wet conditions that would make a down bag no fun to be in.

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

I live outdoors a considerable portion of the year and this is a definite dont "leave at home item". It is pricy but this bag is no kidding around, awsome. I am an extreme minamalist, due to my work load. this bag is about as light and as warm as you could possible get for a 45 degree bag. I often wake up soaking in sweat busting out of it, to get cool again(sleeping in uderwear only). It is completely cozy at 45-60 degrees, hot at the 70's and above. Throw in a SnugPack ultra light bivi, you have a sleep system super light (3lbs) and still comfortable. oh, im 5ft 11in, 170lbs and a belly sleeper with no problems in this bag. All around incredible buy

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

Used this bag on a 8 day canoe trip up the Allagash waterway in Maine and a 6 day backpacking trip in the White Mountains. The dual-zipper setup took some getting used to, but I like it now. Though the zippers snag pretty easily some care can ensure this doesn't happen too often. The bag stays warm and is sometimes difficult to vent, especially in the footbox. But in weather down to 35 I was comfy with only a sheet as a liner. Love how small it packs, love how light it is. Solid bag overall.

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

I purchased this bag for summer camping and floor crashing. I liked that it is light weight and has a small pack size. What I did not like was the length of the zippers. There is a half length zipper on both sides. I would have liked one of them to be full length.

Comments about Mountain Hardwear Ultralamina +45 Sleeping Bag - Regular:

Comfortable and lightweight, stuffs very small. We own 2 of these bags and really do like them. Have used them for 2 seasons down to 35 degrees. I use a hammock and tarp system with this bag. Easy to pack and keep clean. Zippers do snag on every pull. Sure is annoying in the dark.
