After 6 nights, got a hole

1 year ago

I used the pad about 6 times before it got a hole and would deflate by morning. I should also mention that I'm pretty uptight when it comes to my gear and I treat it really well--i.e. this is not a user error. I tried finding the hole but was unable to do so. Still it would deflate at home when I left it alone overnight. I'm returning it. Otherwise, it was easy to inflate, very comfortable. Other reviewers were right in that it's a real pain to get it in the bag it comes in. Unless I can find another pad at this price point, I might get it again and give it one more chance.

Too thin for a side sleeper

11 months ago

Nice and lightweight. Easy to use and inflate. Mostly self inflates needs just a few puffs of air to fill it completely. I am 5’6” 140 pounds woman. It would work for someone that sleeps 100% on their back. If you side sleep or belly sleep you’ll be uncomfortable. My hands fell asleep. I’ll have to return this item.

Surprisingly Comfortable

6 years ago

When I got the pad, I was not impressed with the thickness. Went on a back packing trip and WOW, thin pad supplied plenty of comfort on my side and lying in my back. I'm 230lbs with bony hips. I love it.

keeps you off the ground

Purchased 3 for Philmont. Myself and two boys. Let us keep almost everything in our packs. Only issue was a hole in one of them because of sleeping bag zipper so bring some kind of seal tape.

While the pad is great it’s almost impossible to get it back into the stuff sack.

Firm Thin Pad

3 years ago

This pad is a good pad but not the best there is. It is light, it rolls up to a decent size, and it has cushion. However, in my use it doesn’t self inflate well and is very firm to sleep on. The pros are the rubber grips keep it from sliding around in the tent and it pairs well with other sea to summit sleep system products. I give it 3 out of 5 because it could pack down smaller and be more comfortable.

Two pads, both quickly got holes

11 months ago

I bought this pad two years ago and after using it perhaps 4-5 nights, it got a hole and I returned it. I hoped this was a fluke, and after researching other pads, it seemed to be the best bang for my buck, so I tried it again: I ordered another one. This pad lasted about 30-40 nights total before producing another hole, and this time it was 2 weeks into a 4-week section hike of the PCT. This time, out of necessity, I tried patching the hole three times with the three sticky pads that were included, but the patches didn't keep the air in. I also found that the hole was located near the foot of the bag, exactly where the pad was folded in half before being rolled up from the foot-end of the pad. In another words. the hole occurred not because of my misuse but because of the way the pad is designed--that is, to be folded in half before it can be rolled up so as to fit in the bag. The take away: if you're going to risk getting this pad (or already own one), DON'T fold it in half when rolling it up to fit in the bag. Yes, this is a drag because the pad will now be twice as long as it had been, you can't use the bag (which it barely fit into anyway), and you will have to be secure it to your pack in a new way (not a big deal either). But I wouldn't trust this pad on any long hike.

Good pad, does not pack down super small

3 years ago

All the reviews had great things to say about this mat; however, it did not back down as small as I was hoping (it's probably the size of a 2L nalgene). I returned for the Sea to Summit Ultralight Insulated pad and was very pleased.

Don't buy

2 years ago

I bought this sleep pad 15 months ago and used it for three nights. It worked as expected. Just took it with me on a second trip for a three week Colorado River trip and it went flat the first night. Not cool. I've got the patch kit, but finding the leak is impossible. Of course, I'm past the return window.
