It is interesting seeing what works and doesn't work for different people. Darn Tough socks have been fantastic for me, they stay in place, don't stink, are comfortable, and durable. All of my First Lite gear has held up really well (Corrugate pants, Kanab 2.0, Beanie, Chama, Etc.) with the exception of their liner gloves and the Llano, but even the Llano has been pretty good. I've had it for two seasons and I wear it a lot outside of hunting purposes. It's developed two holes on the body and the thumb holes are starting to show some pretty good wear but I fully expect to get 2-3 more years out of it. That said, my Minus33 merino top feels a bit nicer on the skin and has held up even better (granted it's more in line with the Chama material thickness). I also prefer the collar on the Minus33 over the Llano as the Llano can sometimes rub wrong under a pack. If the Minus33 had thumbholes I'd say goodbye to the Llano. I'm interested in the aerowool QZ top but if the collar is like the Llano I don't know that I'll buy it.
My biggest disappointment hasn't been that bad but it's probably a Vortex Viper rifle scope. It's not their top of the line scope and certainly not a bad budget scope but for the money I like my Nikon Buckmaster scopes better. Plus, since I was an idiot and went with a 50mm objective it required taller bases, which changed my cheek weld and I had to add a riser on the comb, etc. If I could do it again I wouldn't have purchased that scope but you live and learn. My opinion of Vortex has changed with the scope, however, as I certainly feel there are better options out there for the price. Their warranty is great, but quite frankly, I'll probably need to use that warranty at some point (and have).
