I'm looking for the following:
1. socks for hiking, that very comfortable and dry fast.
2. sock for hiking in cold weather, like thermo socks. (32 farenheit)
3. t-shirt long-sleev, fast dry
4. t-shirt long-sleev, thermo for hiking in cold weather (32 farenheit), fast dry
5. second layer protection sweater, light, for hiking in cold weather (32 farenheit)
hundreds and hundreds of options to chose from, and everyone has solutions. Just pick some thermals, a waterproof jacket, a down puffy jacket, hat/gloves, pack your pack and get out there to start testing stuff.
You will go through a bunch of stuff before you fine the combination which works for you (and your budget), but you need to get on the trail to work it out.
2. Same as 1.
But you know that each person is a bit different, so you should try several vendors before settling down and purchasing. No need to waist money 🙂
A lot of great insight and suggestions already but I'll add my own two cents.
First, I am 6', 200 pounds, and average build...
Socks? I love my Darn Tough crew socks and Injinji toe sock liners, paired with my Merrell Moab 2 vent shoes (I prefer the heavier-duty shoes over trail runners but not the bulkiness of boots)
My primary hiking shirt is my Outdoor Research Echo sun hoody. In warmer weather, that's all I wear (for my shirt anyway). On cooler days, it then serves as my base layer with a fleece or shell on top.
For pants, if it's hot I am wearing my Trailhead shorts from Coalatree and, if it's cool enough for pants or where ticks are a huge threat, I wear my Trailhead pants (as you can surmise, I like the Coalatree stuff).
Other clothing I carry:
My favorite hiking/backpacking shirt is an NRS silkweight paddling shirt. Comes in men's and women's versions! UPF 50, hood or no hood, cool, quick drying, comfortable. Helps keep me cool and comfortable in really hot weather. I have several and love them all.
Lots of good info here. I have picked up some great ideas. My favorite sock are Darn Tough merino, with a lean to the full cushion. Do not buy DTs unless your sock supply is extremely low. My preferred sock was the REI light hikers until I bought a pair of Darn Tough. I still like the REI sock, but when they are worn out, I will replace with Darn Tough. You will love the way the DT fits and massages your foot. I have worn other wool socks, but I will stick with REI and Darn Tough as long as they remain quality like they are.
