Folded Thinlight Foam Pad – 1/8in

Jump to: Our Verdict / Features / Specifications

UOG TOP PICK – For Ultralight Versatility: Simple, packable, and weighing just 94g, the Gossamer Gear Folded Thinlight Foam Pad provides protection, insulation, and structure without bulk, making it an ideal companion for inflatable mats and minimalist setups.

Gossamer Gear says: 

The Gossamer Gear Thinlight Foam Insulation Pad is the sleeping pad of your minimalist dreams. With 12 different uses – from adding insulation to your sleep system to its use as an on trail yoga mat, there is every reason for a thinlight pad to be an essential part of your ultralight backpacking kit. The average weight of the new Thinlight pad remains the same as previous versions.

R-Value: We have not determined a R Value or temperature rating for the closed cell foam due to its variable density – but based on thermal conductivity data compiled by an independent scientist, we estimate the R values to be 0.5 for the 1/8″ Thinlight.

Please note that some pads will feature scuffs, small air pockets, or creases. This is cosmetic and does not affect performance. The folded pad perfectly replaces the sit pad in a size medium pack without any trimming. NOTE: sizes may vary by up to ½” length / 1.3 cm

Our Verdict

At 94g for the folded version, it’s not something I’d rely on as a standalone mat, but paired beneath an inflatable, it earns its place. It provides a valuable layer between the air mat and the tent floor, reducing the risk of punctures and adding enough insulation to remove the edge from colder ground. It also helps stop mats sliding around on slick silnylon floors .

Beyond sleeping, it works well as a sit pad or for pack structure in a frameless pack. The folded design slots neatly into a pack sleeve or can be reconfigured easily depending on the day’s needs.

The Thinlight doesn’t try to be flashy or overengineered; it’s a simple, functional piece that plays well with the rest of a sleep system. If you’re looking to protect your mat and gain a bit more versatility without excess weight, it’s worth a look.
