Thanks... I planned on either Kuiu or First Lite... Looks like the Kuiu may be a looser fit than first lite? Hard to tell with just the pics on both sites... Kinda thinking I want a more snug fit with my base layer as that's what I'm used to...
My tight fitting base layers relax a bit but don't get "loose" my loose layers do get a bit looser but not bad. Loose fit boxers stretch a bit and I am planning to try a boxer-brief style next to combat that and hopefully one with a non merino "standard" style elastic waist band as well. I am curious what others think on this and I have admittedly not tried the Darn Tough socks that so many love but so far about 85% merino wool content with a good elastic type poly material in key places making up the other 15% seems to be the key to keeping socks fitting good for me. I started wearing Merino in Iraq a couple years ago after seeing what happens when UA burns!! I love the stuff and have worn it from 130 down to -40.
I have picked up some Kuiu merino for hunting, but I have also found some great deals on Smartwool and Icebreaker merino stuff at Sierra trading post. I'll be using a new merino t-shirt on a backpacking trip this weekend.
I've not had an issue with stretching when wet. It gets a bit more baggy/heavy when drenched, similar to other fabrics. After drying out it seems fine and goes back to normal on the fitted or loose fitting Icebreaker garments I have.
+1 for me in warm weather as well. Thin ,merino wool for me in hot weather and long sleeves that I can roll up if I want to or keep down for bugs, and sun. If I do get into real hot weather, 90-100+ degrees and sweat they dry out pretty fast. The no stink factor for multiple day trips along with all the other plus factors of merino wool are awesome.
