Kanpai Bottle - 10-16.9oz by Snow Peak — One of my absolutely favorite, most utilized pieces of gear. Its a double wall, titanium thermos that comes with a sipping lid, a hot thermos lid and a cold lid. I throw my coffee in my pack and switch to the sipping lid when I get to my glassing spot, summit etc. The bottle will also fit a beer can so you can add use the cold lid to keep a drink cool.
Wildfire 2 Hiking Shoe - Men's by Salewa — Fantastic shoe for training hikes, peak bagging and throwing in your pack for long hikes out of the backcountry in the Spring.
Tributary Stockingfoot Wader - Men's by Simms — Like many of my recommendations on here, I'm always looking for the best compromise between performance and price point. You can spend 4x as much on a pair of waders. And, they are probably better than these. But, do you need to spend 4x as much? Probably not and you'll be perfectly content with these.
Men's Ridge Merino Wool Boxer Briefs by Ridge Merino — Merino boxer briefs... for when you are going to be wearing the same undies for days on end in the backcountry.
Alpine Start Hooded Jacket - Men's by Black Diamond — I have this jacket on my splitboarding list already, but I can't say enough about how impressed I am with the versatility of this jacket in the mountains.
Men's Alpenglow Pro Hoody by Black Diamond — Absolutely the best sun hoody on the market. Generous length chest zipper to scrub heat + vented armpits + a multi panel hood that "hooks" under your hat to cast the most amount of shade across your face.
