Problems keeping your brain housing group heated? What you need is a space blanket for your head. Columbia has your noggin covered with their new Omni Heat technology, built into the Mountain Guard hat.
Omni Heat uses space blanket style dots to reflect heat back to your body while allowing moisture to escape between the dots. The claim is 20% more warmth, and while we can't vouch for the exact amount the Mountain Guard hat sure does the job.
Omni Heat is just part of the story here. The thick hat is half acrylic half wool, and the ear flaps are perfectly sized for full coverage of your luscious lobes. Don't need them? Button them up and out of the way. The interior is a soft fleece and the overall feeling is plush. The Mountain Guard hat is warm and well-designed, not to mention pretty cool looking.
