(climbing) Fear & Loathing (in Las Vegas) 

Lol, well there's the enjoyable and not so much!

Thank you. I'm still planning on releasing these pitches in the traditional format however, I'm toting with the idea of doing a video like this for each multipitch I film.

looks to me like a patagonia r1 baselayer of some sort, the current offering from patagonia that I assume is closest unless you shop thrift and used gear stores is the capilene air grid style fleece, retains warmth but is breathable, or maybe just the capilene baselayers depending on density. even the cool daily long sleeves seem to hold up pretty well and find them to be really really comfortable in warmer temps. hope this helps and maybe we can get Mr. FirstPersonBeta to answer also. Cheers.

Staley nailed it. Patagonia R1. Useful 3 seasons a year. Definitely worth its price.

@@FirstPersonBeta Thank you both.

Correct.
