Why We Like The Comfort Plus SI Sleeping Pad

Light and plush, the Comfort Plus SI gives us a little luxury on the trail. This pad's multi-function valve ensures a quick inflation, saving our lungs, while its featherweight core technology feels like a cozy cloud under us. No matter how active our dreaming, the silicone print stops us from slipping and sliding right onto the ground.

Very satisfied after my first night using it.

[This review was collected as part of a promotion.] Definitely more comfortable than a standard air mattress.

Good but not best

[This review was collected as part of a promotion.] Thought this mat was going to be very comfortable and it is. But to achieve the best support and warmth rating it needs to be fully inflate. It is still comfortable but as a side sleeper It feels a lot like a balloon in that it doesn’t cradle the hips and makes you feel like you want to roll forwards or backwards, like it’s very bouncy. Deflate it a bit and it really starts to feel good but then hips start to touch ground. Mat needs some dimpling or something to get rid of rounding feeling. It’s a comfortable mat at the top tier of comfort but mats like the boundry deluxe seems more comfortable because of the dimpling cradled the body better. If it’s a warm night and you can let some air out it’s good. I’m 6 4” 220-230. If you are lighter you will do better.

I'm using this in my

[This review was collected as part of a promotion.] I'm using this in my van that I use to travel in. It's on the heavy side but I'm not a thru hiker. On short overnight trips I'll use this for the extra comfort it gives over the thicker fully inflatable pads.

Great Matt!

[This review was collected as part of a promotion.] I purchased this for my 6 foot for nephew, and he thinks it’s great. It’s hard to find something to fit a tall, broad shoulder teenager whilst also being relatively small to pack in a bag. This one is just right!

Leaking mat

[This review was collected as part of a promotion.] My original mat I bought from you guys had issues with leaking through the foam mat part. I was very happy you replaced it free and the new one works great.

Solid kit

[This review was collected as part of a promotion.] Top notch kit as expected from sts. I'm a larger ape so the only gripe would be the width and the pack size(everyone wants pack size reduced but you can't argue with physics). Well done with this product.

Great sleeping pad!

[This review was collected as part of a promotion.] This is the best low profile sleeping pad I have used so far. I have tried several cheaper pads but they don't last and are not as comfortable as the this one. I have only used it about 5 times but it seems to be holding up nicely.

Awesome mattress!

About to order two more so the kids don't wake either other up rolling around all night on traditional air mattresses!
