Since I found quilts I have come to the realization that I will never move back to sleeping bags ever again. This is more because I like to move, or more correctly, I move a lot regardless. Sleeping bags have been uncomfortable forever and I used to unzip them on purpose to get the freedom to move.

In this Nitro quilt, I found something that is nice quality, lightweight and durable for my use as a week, section and thru-hiker. I hope you decide the same or for the first time become aware of the quilt world and maybe you'll be sucked in like I was!

Independent Reviews and Recommendations for Sierra Designs Nitro Quilt

Section Hiker

is a very odd-looking quilt that doesn’t look a whole lot like the other backpacking quilts sold today. However, the head covering system is quite comfortable and helpful in staying warmer.  Still, the quilt does tend to flop open when you roll around at night, letting cold air in since it doesn’t have a pad attachment system. Read more...

Our take If you like a quilt’s roominess but do not like letting all your heat escape every time you roll over, the 800-fill Nitro Quilt and its smart design set is just what you need. An integrated footbox, head hole, and two interior hand pockets at the top corners give you comfortable spots to tuck your extremities, making custom coziness easy to dial in. Read more...

What Sierra Designs Customers Have to Say About the Sierra Designs Nitro Quilt

Rated year-after-year consistently with good reviews on Sierra Designs, this quilt comes highly recommended.

Great versatile quilt. Recently tested camping at 9000 ft in 20 degrees and was very warm. The reason for 4 stars was that I wish the arms were a bit longer and the sides a bit wider to tuck. I have long monkey arms at 6’ 1” tall.

I rarely write product reviews, but I love this quilt. Its maiden voyage was two nights at the South Rim of the Grand Canyon, followed by two nights in the canyon- lows at the top got into the mid thirties, while the bottom was in the mid sixties. I was toasty warm in the mid thirties in thermals and a knit hat, and kicked my feet out at the bottom to stay cool.

I am in love with this quilt. I'd been using a down bag unzipped as a quilt for years and finally decided to track down a proper quilt for weight-saving purposes. Depending on my mood, I will sleep on my stomach, my side, or my back.

With this quilt, I was able to do all three. I've got a pretty wide frame and the quilt still hit the ground and kept me warm while side sleeping. The pockets for hands made wrapping up easy while stomach sleeping, and the hood-like pocket kept my head and face warm while sleeping on my back.
