Companies like Sitka, Kuiu, Kryptek, and First Lite cater to hunters all have 'clothing systems' to suit your needs. But you can surely substitute in garments from outdoor brands found at places like REI. Marmot, Patagonia, Smartwool, etc...
I'd be looking at a quality merino base-layer (top & bottom), a wind cutting mid-layer top, durable 3way stretch pants w/DWR treatment, a packable 'puffy' insulating layer, and a wind/waterproof hard shell outer layer(top & bottom).
Round it out with: Darn Tough merino socks, plus quality beanie hat, gloves, & neck gaiter...
Have fun!
Good wisdom. I have spent hundreds upon hundreds of days at high elevation in the rockies. All doing moderate to heavy exertion with periods of stopping. Backcoutry Skiing with no snowmobiles and hunting mostly.
Any good base works, I use patagonia, works best for me (love wool but it bugs me when i sweat much). I wear mid weight wool pants (whipcord) and gaiters. I have worn softshell pants a lot of times too, depending on weather. Wool sweater or fleece and a lightweight softshell on top. A baseball hat above 20, beanie below 20, lightweight windstopper gloves that offer good trigger manipulation.
In my pack: pants and jacket of lightweight Waterproof material, Oversize on jacket, gets used rarely and overized can fit over next item to block wind and moisture and trap
Heat, A lightweight down jacket or sweater in my pack, spare light gloves, big mitten and heavier hat.
Spare socks!!!
I like to start my hikes cold. Pretty damn cold for the fist 400-800 yds moving quick. Then I am not overly hot the rest of my day or stopping to shed layers a bunch.
I have trouble with cold feet, but plan on using antiperspirant this year to keep them From sweating which is, according to our Experts from AK experience here on the hide, one of the big problems with this.
The only "hunting" designed stuff and brands I have are things my wife bought me because my friends told her they seemed cool. Most of it is just good quality outdoor gear. Check out GoLite too. Cheap at outlets, light weight which is huge when hiking 10+ miles in mtns daily, and holds up crazy well for me so far. I hike a ton and sit very little so YMMV.
Have fun and update in the huntig thread with your success story and pics!
