Winter adventurers, meet your new favorite hat! The Tillak Tahoma is seriously the ultimate cold-weather companion. The outer shell is 100% nylon with water and snow-repellent treatment - perfect for those snowy hikes or ski days. But here's the cool part (pun intended): it's fully insulated with synthetic fleece lining AND has these awesome ear flaps you can flip up or down depending on the temperature. Getting too warm? Just flip the ear flaps up for some ventilation. Feeling the chill? Flip them down for maximum ear coverage. The adjustable spring cord system means it fits head sizes from about 20.5 to 22.5 inches perfectly snug. There's a compact brim that keeps snow and glare out of your eyes without getting in the way of your vision or helmet. At just 3 ounces, it's incredibly lightweight and packable - stuff it in your pocket or backpack without thinking twice. Whether you're backcountry skiing, snowshoeing, winter camping, or just walking the dog on a frosty morning, this hat keeps you warm, dry, and comfortable. Plus, Tillak gives 1% of revenue to environmental causes through 1% for the Planet, so your purchase actually helps protect the outdoors you love. It's the winter hat I didn't know I needed until I tried it!
