While fancy stainless steel vacuum-sealed water bottles are all the rage, sometimes nothing beats a classic cycling water bottle, particularly when you're trying to minimize weight, like during day hikes. Best of all, this one is 'Hyper Green,' so you're unlikely to lose it.

Never lose sight of your favorite tasty beverage again with this nifty glowing coozy. A small LED strip provides illumination for up to 100 hours using a replaceable CR2032 battery, the same used by Apple Air Tags.

Socks are a supremely underrated holiday gift, especially when they are as soft, cushioned, and stylish as these bad boys from Stance.

Buff is the original neck gaiter brand, and I've been a fan of their products for years. During the winter months, I rock a heavy-duty fleece gaiter, while in the warmer months I switch to an ultralight one with UV protection. This deal is on the latter, which comes in 'Smooth Violet' and is rated UPF 50 against UV light.

A classic 32-ounce Nalgene for just $10 is an absolute steal in my book. Plus, the blue transparent sale model features funky-fresh REI 'Opt Outside' branding. Don't like the design? Cover this sucker in stickers like it's 2003 and you're an angsty teenager.

This folding seat cushion from the legendary outdoor gear brand ALPS Mountaineering weighs just four ounces and collapses down small enough to tuck into a backpack water bottle pocket. Perfect for campers and/or sports spectators, I can personally attest to the comfort of this pad.

In addition to foam camping and seat pads, ALPS Mountaineering makes some of the best inflatable camping gear, including this crescent-shaped pillow, which is an absolute essential for nights spent in the great outdoors.

Be the envy of your campsite, tailgate, or bonfire with this sleek and effective beverager chiller from GSI Outdoors. Available in 'Haute Red,' it's designed for 12-ounce slim cans (think Red Bull, White Claw, etc.). A nifty screw-on collar keeps the can secured, while double-walled insulation provides reliable chill-ability.

Farm to Feet makes some darn-confy socks, and these light, cushioned hiking socks are no exception. Constructed from 72% Merino Wool, they make a great gift for just about any outdoor lover.

No, this double-layered fleece neck warmer isn't made from actual 'turtle fur,' it's 100% recycled polyester. Ideal for extreme winter cold, choose from three stylish colors, including 'Royal Purple' (shown here), azaela, and classic red.

While the ALPS Mountaineering Crest Camp Pillow above weighs a manageable eight ounces, the Versa Pillow weighs just 3.8 ounces and packs down to roughly the size of a baseball when deflated.

This classic, cuffed, striped beanie is made from a breathable, moisture-wicking material to keep your head warm and dry all winter long. Unisex and stretchy, this toque should fit most domes.

Similar to Outdoor Research's beanie above, the Melody Earband is designed to keep your ears warm, dry, and comfortably cushioned in even the chilliest temps.

Built with trail runners in mind, the REI Co-op On the Trail Cap is stretchy, low-profile, and adjustable via a rear bungee-style cord. Ventilation holes ensure a cool head, while UPF 50+ sun protection should keep you safe from UV rays.

This casual and cool-looking ball cap is made from 100% cotton corduroy and features brass hardware around the back for a vintage vibe.
