I've been wearing the Stretch air Gladiators this year. So far, so good. They've been durable. No crotch blow out. Only problem is staying up. I found some suspenders which solved that issue. I put them on in the morning and wear them all day, everyday, climbing and groundwork. Yes, they are warm but really I sweat anyway in the summer so it doesn't make that much of a difference. So far this year it hasn't been cold enough to warrant thermals and it's been down to the mid 20's F around here.
