A Quality Pad

  • Familiarity: I've put it through the wringer

So overall- I love this pad! It's exactly what I was looking for. It is SO SO much more comfortable than my Thermarest Z rest. It is very lightweight, which is a huge plus, but I will say it's not as small as I was expecting. If you don't have a stuff sack or some other way to keep it small and just use what they give you, it's about the same size as my sleeping bag, roughly two nalgenes (think stacked one on top the other). The sack they give doesn't do anything to make it smaller, so if you need space I suggest buying something extra. I'm using velcro straps to keep it small, and just wrapping it in cloth to avoid damage.
It is super SUPER comfortable- and such a great deal for what is offers. I am 5 6' and wish I had gotten the shorter pad because this one is a bit too long for me, but I have always woken up with sore hips because I sleep on my side and noo moreee! I am so stoked on this bag and the many journeys it will accompany me on.

Quality pad !

  • Familiarity: I've used it several times

Pad is been great . It is great for giving some extra insulation on cold nights . I really like the exterior of the pad . Has enough grip to keep you from slipping and sliding all night . Can't say enough about how impressed I am with this pad .

Pure comfort

  • Familiarity: I've used it several times

Therm-a-rest sure knows how to make a great quality sleeping pad, and they won't let you down with this one! This sleeping pad is so comfortable, and it keeps you warm too! I purchased one for myself, but now I need to get my husband one so he doesn't end up stealing mine! This pad also packs down pretty small! We joked that we would never get it back down to the size it comes as when you first order it, but you really can get it down almost as small, which is great! More room in the pack for gear!

Great comfort in a lightweight package.

  • Familiarity: I've used it several times

I just took it on a trip to the Absarokee Mountain range for 4 nights and it was great, the price was even better.

Big comfort in a small package

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

When I rolled out this sleeping pad for the first time, I was a bit concerned that its footprint would not be sufficient to keep me comfortable if I moved around during the night. What I found was that when you are comfortable, you sleep, you don't roll around. Waking up at dawn to go fishing was so much more enjoyable after a good night's sleep.

Durable and comfortable

  • Familiarity: I've used it several times

Used it for a backpacking trip, light enough and very comfortable, slept great on my back and side, holds air really well. Durable enough for two long nailed dogs that trashed all throughout the night.

Great sleeping pad

  • Familiarity: I've used it several times

I recently used this pad on a 7 day camping trip in the rockies. It got down into the 30's a few nights and I didn't feel a thing as far as cold under me. I was able to slide my feet off the edge and feel the cold coming up through. I have a Big Agnes bag that this pad fits perfectly in the slot. The self inflating works great, but doesn't quite get firm enough for me, I had to put one breath in. I slept on my side, and back and never touched the ground, quite comfortable all around.

Essential for camping

  • Familiarity: I've put it through the wringer

I have slept 2 months in a row camping and this pad makes the difference. Not only it keeps you isolated from the cold ground, but also saves you from having a sore back for the rest of your hiking.

So comfortable!!!

I want to take a nap on it right now.

Great pad

  • Familiarity: I've put it through the wringer

This is the first inflatable pad I've purchased, and I'm thoroughly impressed. When blown up completely it supports my weight and it also fits perfectly in my bivy system. It was interesting one morning, when I went to pull my sleep system off the ground the snow underneath hadn't even melted, Which I think is a good testament to this pad.

Great Pad

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

I used this pad on a recent ski mountaineering trip in Colorado. The pad packs down to a small size easily and quickly and is light especially for a self inflating. It is quite comfortable to sleep on and it is the first pad I have never slipped off of. We slept directly on snow with temperatures in the 10 to 20s. I had a 20 degree bag and was comfortable with minimal clothing underneath. Great insulation. Overall this is the best pad I have ever used and will replace all my pads including my 3 inch car camping pad. Very pleased here.

Very Happy Camper!

  • Familiarity: I've used it several times

I was hesitant about using this pad - wondered how I would feel on the 1 1/2" thick pad. Usually my hips bother me on too hard a surface but was very pleased that after 4 weeks of constant use, it performed beyond my expectations. I am a side sleeper plus I toss and turn alot - highly recommend this pad for year round use. Also packs away decently at 4.8" x 11" and quite light.

I'm a side sleeper. Do you recommend this...

I'm a side sleeper. Do you recommend this pad? What's the pack size?

Best Answer Responded on

The Therm-a-Rest ProLite 4 is a substantial 4 season pad, nicely thick, and should be a good comfortable option for a side sleeper. Packed dimensions are approx: 11 x 4.8 / 28 x 12

Great pad!

  • Familiarity: I've used it several times

Have had a no-name pad for about 12 years and it worked well, or at least I thought it did until I got this one when my old one developed an un-patchable hole.
Camped with this one in below freezeing conditions, and I was snug as a bug in a rug, while almost everyone else on the trip (including my tent-mates) commented the next morning on how freezing they were. I've camped in similar conditions with the same sleeping bag, but old pad, so I'm able to compare the two different pads independently, and man, this one made a world of difference!
Used to wake up with large bruises on my lady-hips from my old pad (which was thicker than this one), but have yet to have it happen with this one - I'm very impressed!
Definitely definitely recommend to anyone looking for a new, packable, warm, and comfy pad!

Specs for Prolite 4

Specs for Prolite 4

Since these show up on sale from time to time, and there's no specs listed for this specific pad, I thought I'd contribute. Looks like the regular size is 20 x 72, 1.5 in thick, 1 lb. 8 oz. and has an R value of 3.2.

How does this differ from the Prolite and...

How does this differ from the Prolite and the Prolite Plus? I can't find the "Therm-A-Rest Prolite 4" on REI's or Cascade Design's site, nor can I find specs for anything called the Prolite 4.
Is this lighter/thicker/warmer/better than either the Prolite or Prolite Plus?
Help.

The ProLite 4 is a 4-season alternative to the ProLite sleeping pad with more warmth (r-value of 3.2). The ProLite Plus is an improved version of the ProLite 4, offering even more warmth (r-value of 3.8) at a similar weight (ProLite 4= 24 oz and ProLite Plus=22 oz). Obviously, this difference in product efficiency is reflective in the price, the ProLite 4 is $94.95 and the ProLite Plus is $109.95.
