For a warm sleep we need a sleeping mat Rab Stratosphere 4 for spring summer and autumn camping. The cushion features synthetic insulation and over 3 inches of thick cushioning to reduce convective heat loss and increase comfort with larger external air chambers which keep us in the center of the mat. Rectangular shape allows you to sleep in multiple positions - convenient for those of us who turns over at night.
The mat is easy to inflate and deflate with a low profile two-way valve using the included pump bag which saves our energy. prolongs service life and prevents the formation of mold and mildew. It's simple. The pump bag is inserted into the two-way valve. Then we simply trap air in the pump bag and roll it down to compress air into a pillow and inflate it. The pump bag also serves as a compression sack for our sleeping bag to save some weight.
