Taiga® Mini Foam Mat
The Taiga® 'Mini Mat' (made of EVA closed-cell foam) measures 21" x 42" x 1/4".
That's all you need in spring/summer/fall to insulate shoulder-to-knee from the ground.
Cut down to 18" x 38", it weighs a mere 70g.
The Mini Mat currently comes in One Piece. If you cut it into 4 sections and rejoin these with duct tape, you get a flat-folding mat of 1" total thickness when folded (as shown here).
