THis bright yellow pad is amazing.
It is VERY thin, and I cannot recommend it as your only pad, but it is excellent and very durable. A good option for using under and inflatable 3/4 pad in the shoulder seasons. I have had one for over 7 years, and it has held up amazingly well after tons of use on expeditions.
I work at an outdoor school, and I order a handful every season, and when co-workers see this thing, they buy it on the spot.
It’s recommended if you plan to camp on snow in a “summer” environment. I teach on the glaciers of alaska in the summer, and I use a Pro-Lite 3 on top of a MEC evazote 5-mm “bivy” pad is an excellent system.
