Trail Pro Sleeping Pad

Typo: I meant ProLite. It was their original pad, and is still a classic. The current model is Trail Pro. It is slightly heavier (and more durable) than the original. https://cascadedesigns.com/products/trail-pro-sleeping-pad Surplus military pads sell on eBay. Try “USGI sleeping pad” or similar.

I really like the Therm A Rest Trail Pro. It's bulky and heavy, but it's extremely comfortable and easy to sleep on.

Thoughts from an REI employee: Comfort often comes from a few factors, but don't apply to everyone. Thickness can help a lot. The Thermarest NeoLoft for example is very comfortable, because it's a whopping 4.6" thick, and a great surface. Some pads have some foam in them, not just insulation. This is kind of old school, the original Thermarests were like this. This can be nice and plush because you don't have to dial in the air amount quite as specific. Plus, if it loses air, you're at least sleeping on something other than nylon. The Thermarest Trail Pro comes to mind. A little heavy around 2lbs, so not for the UL crowd. But comfy. There is a lighter version called a Trail Pro Lite. They used to sell a terrific pad called a ProLite Apex, but it was discontinued and may not be coming back. Sea to Summit and a few other brands make pads with some foam in them that are backpackable. These are also (mostly) self-inflating, which is nice. The shape of the pad can also factor in. Some people love how most Big Agnes pads are raised on the sides, to help you stay in place, and not roll off the pad. Most of their pads are thick too, not as thick as the NeoLoft, but thick. The Rapide is a great seller. Other brands do this too. I mentioned surface, some have a really nice brushed surface that also helps keep you from sliding off, and from making noise as you move. The Neoloft as mentioned, but the REI Helix is nice like this too. Baffling is also a factor. Some love "dimpled" pads (like the Helix), some like "tubes" either horizontal or vertical. The choice is yours. Closed cell foam are not comfortable. They are not thick. They are not warm at all. And they are bulky. But they are inexpensive, light, and almost indestructible. Anyone who bought a Ridgerest back in the 1990s likely still has it, and it's probably in like new condition.

Thermarest still makes them? I have also seen knockoffs even in non specialty stores.  I have an older Thermarest Trail Lite and Trail pro. The only difference to the classic mats is a few cutouts to make them pack smaller. I adore my Trail Pro. Very comfy, good R value, thicker than the traditional pads, packs reasonably small for it's comfort. 

We just bought new pads this summer for sea kayaking. Space in our boats was an issue so we found a Thermorest model that folds in half before rolling. If space matters this will help. Thermarest Trail Pro Max. As I recall they about 2.5 inches. Maybe 3. Very nice surface and quiet to sleep on. The really cool bit of kit is an electric inflator I bought for packrafting by Flextail. It’s a small rechargeable 4.5 kpa pump that will inflate a mattress in a few seconds. It also has a light and you can even plug your phone in to the battery to charge if you need to.
