    Frostline Hat

    Howling arctic winds and below freezing temperatures have nothing on the Outdoor Research Frostline Hat. The Frostline's Pertex Endurance fabric resists moisture, while its Posh Pile fleece lining insulates and wicks moisture. The zip-out face mask keeps your face covered when any amount of exposed skin could result in frostbite, and the external drawcord keeps the hat firmly in place as you weather another gnarly winter storm.

    This hat rocks!!! I am 5’10 and 160pds. I went with the XL only to have more material to keep warm. There is a tie cord to fasten, so adjust accordingly... backcountry customer service is totally top notch and I have received better help here than in a Nordstrom! As always, thanks Backcountry😁

    Husband loves it!

      I bought this for my husband for Christmas. He works outside mostly and needed a good winter hat (a toboggan doesn’t always cut it!). I was nervous choosing for him, but I read the reviews and went with it. The hardest part of the process was choosing sizes... I measured one of his caps and went with that. It fits pretty snug, but that just keeps air out and overall he loves it!!

      AND.... it includes a tuck away face mask! Such and awesome hat! Thank you for the review.

      Great gift!

      • Familiarity: I gave it as a gift but have feedback to share

      I sent two of these back home to my mom and step dad, so they can match and be adorable. Shortly after receiving them I received a selfie with the full face mask. I think they're stoked!

      Please post that photo!!! Thank you for the review!

      Not only is the face mask the difference, this hat fully cradles your head......skiing, winter guiding are/were my main uses, Ive got long dreadlocks and the XL still somehow fits perfects. the lining is plush and provides awesome comfort.....but that face mask, SO convenient .

      Hey Kam - so glad you like this hat! So cool with the tuck away face mask!

      Fun hat.

      Love this hat, it's warm, good looking, and fun. The face mask has come in handy more then a few times.

      Don't you love the pull out facemask?? Killer feature!

      Thank you for writing!
