very comfortable and easy to inflate
December 22, 2009

compared to my thermarest, this is wonderful. I had a really good restful night.

Pretty Good
July 27, 2009

In comparison to other insulated air mattresses this one is pretty good. I was warm and pretty comfy but this mattress lacked traction and so I found myself sliding off it all night long and would wake up on the cold ground. If your sleeping bag has a pocket to put it in it will eliminate this problem, as would bivy sack I would assume. Overall, Pretty Good.

Excellent Pad
April 11, 2011

My previous experience was with thermarest ultralight for several years. I didnt know what i was missing with the 2.5" of comfort. The pad takes about 2minutes of steady air to inflate. The new brass valve and plastic base seem very secure and tight. Once inflated it fit perfectly into my horse thief. Initially i was tossing and sliding around to find the right spot and once i got comfortable was able to let just a little bit of air out of the pad so my body sank into it and all was well. I really like the idea and ability of flipping the pad so the primaloft is on the bottom vs against your skin incase things get too warm. Wasnt able to test durability as it was my first campout but looks very well made. I will buy again!

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

Great Sleeping Pad
January 05, 2011

This is a great product I have used it on multiple hiking trips. It feels like a full size air matress. It i very durable and it is great for cold weather camping. I used it in 5 degree temps and i stayed very warm. I am 6' 3" and i just fit on this pad, it works great with most mummy bags.

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

Good pad!
August 23, 2010

My first instinct was to go with the Thermarest Neo pad, but opted for the Big Agnes after considering cost and R value. I've used this pad now on two trips, one of which included nights that dipped into the 20's. This Big Agnes pad was very valuable as it kept me well off the ground. I know that the Neo is a few ounces lighter, but the Big Agnes had it beat for cost and R value. The mummy cut may be too narrow for some folks, but I've found it easy to adjust to. Also, being able to pack this pad next to my bag in the sleeping bag compartment is a real plus!


Built for Comfort and Speed
August 13, 2009

I am 6'3 220lbs and have never had a good nights sleep on my Thermarest. For me Thermarests are either completely hard or if I let out a little air for softness, a hip or tail bone pokes into the ground. I blew up the Big Agnes and tried every sleeping position; results were complete comfort. It is also almost a pound lighter (i.e. speed) and packs about half the size.

Love it!

I love this pad -- it's extremely comfortable. I use it for everything from car to winter camping. It's warm, light and stuffs down small. The valve is easy to use and allows you to inflate/deflate the pad quickly. Big Agnes includes a small repair kit (but I've used the pad many time and never had a leak). I highly recommend this pad.

The lightest most comfortable pad I have ever slept on.
February 01, 2010

The best sleeping pad for backpacking hands down. I have been backpacking for 15 years and I have a bad back. This pad excels for weight which is next to nothing and is also the most comfortable sleep I have ever had on the ground. It is not self inflating, which I do not mind, just don't wait until you are ready to crash to blow it up. I really like that it is not self inflating when it comes to packing it up because it deflates and stuffs quickly and easily.

Great in urban emergency conditions, too!

I haven't used my pad out in the back country yet, but a massive ice storm hit where I was visiting relatives, cutting off all power. I slept on the floor in about 45 degree temps in the house. I was never cold or uncomfortable. I'm sure the insulation would work in colder temps, too. I'm sure I'll get my 1st good nights sleep on the trail with this luxury pad!

Good Product
April 01, 2012

The Big Agnes mummy pad is a great product. It takes a while to inflate but seems to be a durable and solid product. It's very compact and light which is a major plus when backpacking. This product is definitely a bang for the buck type of product.

Pros: Build quality, Ease of use, Great value

January 28, 2010

With some minor back problems, I was concerned with the quality of a mattress pad. This one was easy to inflate/deflate, easy to pack, light to carry, and joy of all joys, my back did not hurt when I woke up in the morning. Pairing the pad with a Big Agnes bag equipped with a pocket ensured that I stayed on all night. I am buying one for both my husband and my son.
