Ultralight Insulated Sleeping Pad

If you're going to be facing some cold nights on your backpacking trip, bring the Sea To Summit Ultralight Insulated Sleeping Pad to boost warmth without adding weight. Thermalite insulation traps warm air and protects you from the cold ground, and Exkin Platinum thermal technology uses a super thin lightweight metalized layer to reflect heat back to your body. Air Sprung cells evenly distribute pressure so the pad conforms to your body for a comfier feel than traditional baffle construction, and it makes the pad extremely packable. An anti-odor treatment keeps odor at bay, and the tough nylon fabric won't get shredded when you decide to sleep under the stars.

The multi-function valve has a one-way valve to make inflation easier, and it has a button you can press to slowly release air for fine-tuned comfort. The rapid air dump port lets you deflate quickly when you're packing up. It also comes with a stuff sack for convenient storage and a repair kit so you can fix tears in the field.

Woke up on the ground all three nights backpacking. Back still hurts from two weeks ago. Save your money.

Super light weight and quick to setup!

I've used it several times

Awesome light pad for any sort of long backpacking trips that are super comfy for the weight. I would lean towards this pad as more of a thru-hiker piece since its incredibly light and the pack size is tiny !

Comfy and warm!

I've used it once or twice and have initial impressions

This pad is very comfortable and warm while you are sleeping on you back or stomach. I liked the way this pad is hugs your body, it does not feel like you are laying on an flat board like some other pads I've used. The only caveat is If you are a side sleeper it does not quite have the support or thickness to keep you hips and shoulders off the ground. The odd thing though is it was not that uncomfortable even though my hip was on the ground and it created a cold spot it supported the rest of my body well enough that I did not wake up sore. The pad supported my body well enough that, while my hip was on the ground, it was not bearing a lot of weight. Overall its a cool and comfortable design and I hope to try some of their more supportive models, like the comfort light or comfort plus, in the future.

Light, Comfy, Warm

I've used it once or twice and have initial impressions

I used this pad while car camping recently in 20 degree weather and it was superb. The adjustable air valve feature that Sea to Summit offers is great for getting the comfort just right. The mat is a little noisy, but for something that is so light and delvers the level of comfort, I can't complain. Can't wait to get it on the trails!

Cushy but Cold

I've used it several times

I ordered this sleeping pad because it was lightweight, had a decent R-value, promised to be quieter than my friends' relentlessly crunchy Neo Airs, and was the right size for me (I'm 5'2"). Seemed like a step up from the closed-foam Ridgerest SoLite pad I was used to schlepping around. After a couple months of use I can say that it's all the things it promised--and I really like the multi-function valve!--but it's simply not as warm as claimed (and I sleep warm). The cold seems to soak upward from the ground. This would be a great pad for someone in a warm climate, or who backpacks strictly during the summer.

What about my knees.

I've used it once or twice and have initial impressions

Just spent a night at probably 10-15F in a OR alpine bivy and marmot col. It was bizarre, I kept waking up because my knees were getting cold. I've never had that happen before during winter camping. Turns out they mapped the insulation to a portion of the pad that corresponds to you lying down on your back with your arms at your sides. I don't sleep like that. I roll and spread out my sleeping bag. No doubt this bag would be good for a true mummy sleeper (light, easy to inflate), but beware if you like to move around on your pad, you may find focal cold spots.

Hey, did you end up buying another sleeping pad? If yes, which one?

The best sleeping pad out there.

I've used it several times

Okay Everyone... This is the real deal! Sea to Summit has been truly innovative with this sleeping pad. For how light and compact this thing is, the price tag is very modest. It rolls up in the included storage bag to about the size of a Nalgene water bottle and it's one of the lightest pieces of gear in my pack. The thickness is just right, not too much but not too little, and the little bit of insulation goes a long way! Other pads can be noisy as well, as they use some materials that attempt to shed weight, but from what I've experienced with this pad, it's durable and lightweight, comfortable, and quiet all in one! The dual function air hole holds air in while inflating without hassle, and deflating is quick and effortless. The material it's made of grips sleeping bags well so you don't slide off of it.

Will this sleep pad fit in the Big Agnes Fish Hawk 30? I know the BA pads are 20" in width and this is 21.5". Just wondering if it would work in that sleeping bag system.
