Cheers for the link - I've been after a local source of the 3mm/1/8" high density foam matting a lot of the US thru hikers have been using as sit pads and to protect and slightly boost the R-value of their Uberlite/Xlite mats. Thought I could get away with a cut down Kmart yoga mat (5mm medium density foam) and was dismayed at the weight - 450gr for 1000 x 500mm! By comparison the 3mm weighs 44g for the same dimensions. 'Practically weightless' isn't an understatement. Both seem to compress to the same thickness too.
To answer Wildwanderer's questions:
From OrangeBrown it comes folded to approx. 165 x 260 x 30mm. When I fold my size 34 jeans to the same WxL, they're about 50mm thick. So, decently smaller... though your jeans may vary
That shape/size slipped without much fuss into the back stretch pocket of an Ultimate Direction Fastpack 30L pack (packed for a 5-day fastpack, minus some food) alongside my wet weathers. Could obviously refold it to suit many other spots - side compression area, bottom of pack (hard to get at as a lunch sit pad though) or as a back/sides former to help a frameless pack carry its load.
Some hastly taken pics below. Hope this helps.

- Minor additional bulge. 30L 95% loaded for multi-day fastpack. Still quite a bit of room.

- Same, side profile. Hard to tell without the mats being held flat, but the 5mm mat is around 40-45mm thick when folded to 165x260mm W/L. 3mm mat is about 30mm and the jeans are over 50mm.
