I have a classic Bozeman Mountain Works Torsolite Self-Inflating pad. This thing for a long while was the lightest inflatable, insulated pad on the market.
Weight is 260grams (9.17oz).
The material is pretty durable, though, somehow
it has a slow leak somewhere. I can't be bothered fixing it for myself and I suffer from TMMS (Too Many Mats Syndrome) and living in a one bedroom unit.
This thing should patch easy when you find the hole using a simple bike tube type patch, or a classic thermarest patch.
These mats go really well with very thin CCF or as part of a compact fast and light set up. Also be a great pad for a child or teenager. The size works well if you use it as part of structure for an UL pack, eg a gossamer gear type pack.
I'd just ask if the postage can be paid ($8.95 anywhere in Aus), or, pick up from me in North Adelaide, as I'm a student nurse at the moment.
