Sierra Designs Nitro 800 / 0 Degree

The Sierra Designs Nitro 800, 0-degree women’s sleeping bag is a lightweight, warm bag that compresses to a small size and is comfortable to sleep in. I’ve been testing the Sierra Designs Nitro 800 sleeping bag all summer and can report that it’s a very warm bag that is lightweight and comfortable. I love my other bag, the Sierra Designs Backcountry Bed, but when the temps dip down into the teens and 20s, I prefer the added warmth of a mummy style bag. I was excited to see this new offering… Full review

Sierra Designs Men's Mobile Mummy 600 3-Season

Who came first, the chicken or the egg? Was it Sierra Designs or Exped? I dunno, but I like it. It's hard to say though whether it's an overstuffed extra long down vest or a warm roomy cocoon for human transformation, but it cries for transportation anywhere in camp. For me this design works the best, as I'm up and down numerous times during the night. With a side zip it works fine until it's colder. Then this bag shines, because I can just leave it on and unzip to satisfy the nature call. I think… Full review

Sierra Designs Men's Nitro 800 / 20 Degree

On a 1-5 star scale it's a 6. Buy this bag. It's the best bang for the buck and SD warranty service is impeccable. I'm stoked on my bad ass SD Nitro. The following is from my review(s) posted on SD's web store: A big upgrade for my gear and a BIG HURRAH for Nate M. in customer service  First about the bag. I received my new Nitro 800 / 20 today and here are my first impressions. After fluffing it up I inspected it carefully. The fabric quality and workmanship are top shelf single malt, so what… Full review

Sierra Designs Zissou Plus 700 2-Season

The design is innovative and the bag bag is warm and roomy made with excellent materials. 5-star warranty, design, materials, and comfort. Minus 1 star for quality control. Short story. I bought this last winter for sleeping in an unheated home in the NorCal coast redwoods that ran 43-48 degrees with high humidity for months and I until then this was the best warm weather bag I've owned and used. I sleep cold, as I'm 66 years old, and this bag was warm from two minutes after I'd slide in all through… Full review

Lafuma Men's Warmn Li 800

A decent quality bag. Lightweight. Meets claimed temp rating (my opinion). Good price. Everyone is different when it comes to how much insulation they need at a certain temperature. I find this bag perfectly adequate at 40 degrees F.  If you are a "cold sleeper" add some long johns and a jacket for the 40 degree rating.  I found it durable and lightweight. I don't see other bags of this quality at this price. Good loft, zipper works fine, nice hood. Stuffs down to very small. Tends to shed water… Full review

Marmot Phase 30

Ultralight, warm, comfortable, tiny pack size, amazing value for money. Everything a sleeping bag should be! EN Rating Lower comfort limit: 30.0°F / -1°C EN Rating Extreme limit: 5.4°F / -14.8°C I am a ultralight "gram counter" when it comes to camping gear and I wasn't happy with my old sleeping bag, which weighed under 800 grams but only had a 8°C (47°F) comfort rating. Then I discovered the Marmot Phase 30, which was a lot warmer (-1°C / 30°F) comfort rating, but more importantly, was… Full review

Kelty Men's Cosmic 20

Massive bang for the buck... Four and a half stars, so far. I bought this bag a short while ago before leaving for my job as a medic in a summer camp in Maine. That being said, the mercury has hit between 90 and 101 everyday for about a week, so this bag with a European temperature rating of 19 degrees has not seen much use except as a bed throw. Even during early chilly nights I mostly used it as a blanket. By today's standards, 600 fill duck down is not the greatest, but back in the day, any down… Full review

NEMO Disco 30

Perfect backpacking bag for side/stomach sleepers. Incredible comfort and weight. While you can certainly get lighter and more compact (for a price), the uniqueness of this bag made it an easy choice. Being a stomach/side sleeper, I struggled with my mummy bag over the years. This easily solved that issue and it was very easy to move around from side to side. The zipper vents on top are also brilliant as I often camp in the summer. Usually I just climb out and sleep on top.   Full review

Mountain Hardwear Spectre SL 20°

Warm, light, packs small, feels small, and is noisy. it is a nice bag for 3+ season use. Likely due to the laminate, it gets damp in below freezing weather; using a vapor barrier liner takes care of the problem. I find that it is very confining in the shoulder area when fully zipped. The sleeping bag makes a lot of noise when shifting around or rolling over. I can't speak to its durability since I have only used it for no more than 20 nights in my five years of ownership.
