Just seen the latest new release from Inov8. 140g for a 20/20 jacket... Be interesting to see how well they hold up with a pack. Specs are impressive but I'm not a fan of Pertex Sheild. Have at it
Personally I find this one more interesting. I won't wear a 2.5 layer unless I really have to. Still don't think I'd trust the fabric though, as you say I've had two separate delamintation incidents with pertex shield, admittedly a few years ago now though.
