You can certainly follow the advice here. But you can go cheaper. Personally after trying a dozen top brands of base layers I’ve decided I like LLBean mid weight merino and Woolx heavyweight merino for base layers. Just like how they perform - the feel on my skin, ability to wick sweat, speed to dry, warmth when wet with sweat, how they hold up to wear and tear and how each holds it shape after washing and drying. I’ve tried Sitka, UnderArmour, Kryptek, Helly Hansen, Smartwool, Patagonia, Eddie Bauer, Ice Breakers, Minus33, etc, etc, etc. LLBean and Woolx work best for me.
If you want camo pants, I find the Kryptek Dalibor pants are extremely durable, comfortable and most importantly quiet (if I need something heavier I wear Sitka Timberline or a handful of other pants I have). Can find them on sale often. But if I wanted to go less expensive and still have good pants, I’d try UnderArmour (I have some and ive got no complaints) or I’d use the synthetic 5.11 pants. I’ve hunted and put an elk in the truck using 5.11s and they are not expensive. Durable as hell and won’t retain moisture.
For tops, I often wear a Helly Hansen zip neck mid weight fleece top over the merino. Extremely light weight. Wicks better than any other top I’ve tried (I’ve tried UnderArmour, Sitka, Kryptek, Patagonia, Mammut, Karbon, Mountain Hardwear and The North Face). It’s cheap and it works. Keeps me dry and warm. I then wear any number of soft shells. My favorites are the Kryptek Dalibor and the Sitka Jetstream. But I’ve worn a Cabelas outfitter windproof fleece and put an elk in the truck. I’ve also worn softshells from many outdoor companies including a cheap one from LLbean that is awesome. Quiet. Cheap and very durable. Water resistant and wicks well. Don’t remember model name. Watch the sales at Steep and Cheap, Sierra Trading, Moosejaw and others and you can get a good softshell from Columbia, Marmot, The North Face and others. Get an Earth tone and it’ll work.
For an insulation layer I’d add a synthetic puffy or one with DWR down and a DWR outer treatment. Costco had a Marmot with DWR down and DWR outer treatment for $60 back in January. I believe it was a 700 full power jacket. Was nice. Had it in gray, dark blue and black. Am sure that the same websites above will offer good options. My current favorites are the Sitka Kelvin jacket, Kryptek Aquillo and the Patagonia nanopuff depending on how cold it will be.
I usually wear a baseball cap and carry a wool beanie. I also bring the Kryptek Norlander gloves which are no longer made but available in the company’s outlet online. Awesome gloves. I also like Outdoor Research and Black Diamond gloves. I’m sure there are others to wear.
I have Sitka, Kryptek and Patagonia Goretex Pro rainwear. First few years Hunting I took LLBean packable rain gear. Worked perfectly. Wasn’t too loud. Very packable. Light weight and kept me dry. I also have a set of Marmot Precip. In my opinion LLBean’s version is better and more durable. Look for sales.
I prefer Darn Tough socks. Look for them at Marshall’s if you don’t want to drop money on them. They are great.
If you want to go full matching camo check Under Armou’s outlet Good stuff. Not terribly expensive. Doesn’t get a lot of love here but I hunt with a couple guides who only wear UA. Also, Camofire has Browning’s Hell’s Canyon on sale today. Good stuff. Not terribly expensive but made well and it works.
