Lightweight luxury.

The Sea To Summit Ultralight Sleeping Pad ensures a comfortable night of sleep without weighing you down on the hike out. It's extremely lightweight and packable so it fits easily in your pack and doesn't tack on a ton of extra weight. Air Sprung cells evenly distribute pressure so the pad conforms to your body for a comfier feel than traditional baffle construction. 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. When you have to pack up in a hurry, a rapid air dump port lets you deflate quickly. It also comes with a stuff sack for convenient storage and a repair kit so you can fix tears in the field when you accidentally slice your pad open while cutting avocados in your tent.

    Noisiest pad I have ever slept on! I am 130#, 5’6”, and a side sleeper. The only time the amount of padding felt adequate and I did not feel the ground was when I was laid completely out. If I ever put more pressure in one spot than anywhere else (ie sitting up), I could immediately feel the hard ground and it was uncomfortable. But more importantly, it is soooooo noisy! Every little movement was heard. It was so loud that my tent partner couldn’t sleep because of how loud it was every time I were to shift or roll over. I certainly did not get a good nights sleep either. I was so surprised as this lad came highly recommended and had great reviews.

    So Comfortable!

      After sleeping on the a yoga mat for a season I decided to splurge with this sleeping pad. It is so much lighter and saves a ton of space in my back. I've never slept so well while camping!

      Get this. Seriously. Buy it.

      • Familiarity: I've used it several times

      Camping has never been so comfortable! I was dubious about how much cushion this would offer, but also didn't want the bulk of a padded or insulated thermarest type thing. This is PERFECT for backpacking since its the size and weight of a beer. We loved it so much we bought one for our friend to keep him sleeping like a baby on a recent fishing trip. Don't hesitate to buy this. It's worth every penny.
      The only thing that I would worry about damaging this is dog claws... We've got a traveling menagerie, and make sure to keep paws off this so we don't risk a puncture.

      Tiny and comfy

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

      This is the tiniest sleeping pad ever when rolled up, but spacious and comfortable when in use. I filled this with air in less than 5 minutes. It held air for 2 nights of camping without any leaks. I slept on some rocks and didn't feel them at all. The color is great too, and I pair it with my Big Agnes purple and yellow sleeping bag for a great combo. Best pad for backpacking.

      UPDATE: I've used this a handful or more times on camping/backpacking trips this summer, and unfortunately I am already experiencing significant air loss. I'm woken up multiple times throughout the night to sleepily blow more air into it only to find it almost flat a few hours later. Luckily, Sea to Summit backs all their items with warranty, but it's kinda a pain to have this issue after only using less than a dozen times. The warranty through Sea to Summit also requires you to take pictures of the mattress submerged underwater in a tub (I don't have a bathtub at my rental house), so extra pain on that end. Probably wouldn't buy again.

      Wouldn't buy any other

      • Familiarity: I've put it through the wringer

      This pad has gone into the backcountry with me for 7 weeks in the past 8 months. I've taken it through the Tetons, the Wind Rivers, the Grand Gulch, and Moab without it taking a scratch. It has yet to be punctured or torn.
      -Extremely light
      -Very warm
      -One-way fill valve
      -Huge bilge valve
      This pad is a good fit for any activity.


      • Familiarity: I've used it several times

      This sleeping pad is not only light (empty coke can!) and packable, it's comfy beyond belief! I was amazed when it arrived in the tiny package but even more amazed how easy it is to blow up and pack back into the sleeve. It takes about two or three breaths and you're on your way to a wonderful nights sleep. I slept on it every night for two weeks and it never lost any air overnight. Do yourself a favor and buy this, now!

      Best rest in even the worst spots

      • Familiarity: I've put it through the wringer

      I bought this sleeping pad the day before I started a month-long bikepacking race this summer in something of a panic. I had a Big Agnes pad, but it was so heavy and taking up a ton of room in my handlebar bag. After scouring the options, I settled on this STS to use for the month.

      Here are some reasons I LOVE it:

      -larger than average valve to pump it up

      -^one-way valve allows you to take breaths between without having to plug up the hole

      -bilge valve for super fast deflation (another key factor for me, as I was looking to be able to get out of my bivy and onto my bike as fast as possible)

      -rolls up to about the size of a Tall Boy

      -provides great insulation and comfort from the ground even on some tricky spots

      I never had a problem with leaks, through a solid 28 sleeps on some very sketchy terrain (rocks and roots and once a baseball dugout in CO), though I was more cognizant of placing my pad on pokey bits than I would be with a thicker exterior fabric.

      I really liked the construction of the pad, the sort of dimpled texture made for comfortable surface, rather than the horizontal baffles which I feel like I'm going to fall off of.

      It's incredibly light-weight, and super small when packed. I could not be happier with my VERY last minute choice on this!
