I have invested a lot of time and money on gear over the last couple of seasons, looking for that perfect layering system, and unfortunately, I haven't found it in any hunting clothing system from a given company. The best layering system/philosophy I've found for backpacking is
this one, from Pro Mountain Sports in Seattle. In summary, it breaks down like this:
- Wicking layer - merino wool
- Light-weight, breathable, non-insulated wind-cutting layer (pants & jacket/pull-over)
- Puffy down insulating layer (Jacket - use when needed)
- Lightweight rain gear (use when needed)
This system is great, considering the goals of the typical person in the back country, e.g. lightweight, versatile (works well when active or sedentary), safe (protects from all the elements). However it misses two goals that are important for the hunter: quiet & color (camo or earth-tone). Also, if you didn't guess it, the second layer is the hard one to find for hunters.
So, after investing in a bunch of stuff from Sitka, FirstLight, Grey Wolf, Rivers West, etc., Here's what I came up with:
Early Season (30-70 degrees):
- Merino wool base layer (Icebreaker Tech-lite T or FirstLight Llano)
- First Light Gila Pants & Grey Wolf Wolfskin Pull-over
- Browning 700-fill down jacket
- Cabelas Pack-light rain gear
I also bring along a second, heavier 1st layer of Merino Wool stuff, too, e.g. FirstLight Chama/Alegheney, for two reasons... I use a light 30 degree sleeping bag so it's nice to have some "long johns" for sleeping, and also just in case I need it if it's extra-cold or if I get really soaked for some reason. The Chama shirt can also be worn in place of the Wolfskin pull-over, since it's both warm and it breathes well.
To sum up, be clear on what
your goals are and what is required of your gear. My list isn't the only way to go, and I still haven't found the perfect second layer. I could easily substitute Sitka gear for much of the list above (core/traverse base layer, mountain pant, kelvin vest, etc.), too.
Finally, I can say that FirstLight (merino in ASAT - awesome) IceBreaker (the best merino t-shirts & hiking socks), Sitka (Optifade + top-notch designs) and Grey Wolf (hand-made to your spec) make some amazing gear. You really can't go wrong with any of it.
