The members here helped me ALOT to get on track with clothing selection for early season!
That said, I wear a light merino base layers, Smartwool/Firstlite/Patagonia, etc. I wear these 24/7, strip down to these base layers for sleeping.
For active hunting, I wear a poly/blend camo shirt over top of base layer. I like my Kryptek Valhalla and spent most hunting time wearing it.
Good lightweight & comfortable pants like: Sitka Ascent/ Kuiu Attack/ Kryptek Alaios, etc.
Keep a lightweight 'puffy' in the pack, like: Primaloft/ Superdown /Nano puff, etc. Slips on easily when idle to keep your core warm. Use as pillow, or sleep in it if your bag/quilt is lacking.
Keep lightweight hardshell rain gear in pack at all times!. My Kuiu Chugach top/bottoms was a lifesaver for when daily drenchings pop up. Top is worn over puffy to cut wind and stay warm around camp early & late.
And don't overlook:
GOOD beanie HAT
GOOD SOCKS
GOOD UNDERWEAR
