So then what are the critical types of clothing I should be looking for after a rain shell (coat)? Also, what brands actually make solid gear and what brands are more trendy? For example is a company like North Face legit and worth some of the prices (lots of sorority girls love those fleece jackets) or is there a better less know company out there that makes great gear and only the people in the know, you guys, love.
I used to make a condescension joke about frat guys wearing North Face jacket. "Oh, you wear North Face? You must go on so many adventures." I personally prefer Marmot and Mountain Hardwear. I'm still wearing some old Columbia clothes and random dri-fit tees such as Nike and some from my baseball days. I still pack my Under Armor for baselayer. All my next clothing purchases are suits for work, Marmot and Mountain Hardwear.
Now that we got the brands out of the way, you might want a mid-weight or lightweight baselayer. If your wallet allows it maybe a insulating jacket to wear under the shells or wear as stand alone around the campsite. Pants, I prefer nylon or polyster pants because cotton absorbs moisture and takes forever to dried. In the winter months a shell pants might be a cool option if you can shell out the dough and live in an area that receives abundant of snowfall. Otherwise nylon pants and a gaiter be alright for winter. Here are some examples in order as mentioned above:
Mountain Hardwear Baselayer (There are thicker ones like this made by other companies or even Mountain Hardwear makes a fleece version like this.)
Marmot Jacket (this is the jacket I have but I don't have the hoodie version)
Marmot Pants Anyway those are random examples, I'll just add go to a outfitter and look at clothes that lacks cotton.
P.S. The only regret I have about my expensive Marmot jacket is I wish I got one with a hood instead. For times I'm in town and don't have my beanie. In the backcountry I always have a beanie, but not always the case in town.
