Pursuit Plus Self Inflating Mat – Regular Rectangular Wide

Jump to: Our Verdict / Features / Specifications

UOG TOP PICK – For Self-Inflating Comfort and Reliable Warmth: With 7.5 cm of cushioned foam, an R-value of 4.2, and a no-fuss valve system, the Pursuit Plus Self-Inflating Mat delivers dependable comfort and insulation for campers who want warmth without the hassle of manual inflation.

Sea to Summit says: 

Intended for comfort backpackers, adventurers or weekend warriors
who demand enhanced comfort, and who prefer a self-inflating over
an air mat. Pursuit Plus is offered in Contour and Rectangular shapes.

Our Verdict

Weighing 1036g, it’s remarkably comfortable for a mat in this category, thanks to its 7.5cm thickness and supportive foam core. The Horizontal Delta Coring trims down unnecessary bulk while maintaining a cushioned feel, which I found particularly welcome when camping on uneven ground. The mat feels noticeably warmer than thinner options, with an R-value of 4.2 providing reassuring insulation for trips into the figures. 

I appreciated the straightforward XPEL Valve System—inflating was hassle-free, and deflating was simple. It packed down smaller than I’d expect for a self-inflating mat this thick, though it still takes up a bit more space than an ultralight airbed. That’s the trade-off for not needing to blow it up manually.

ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
