    Thermal hoodie

    Posted by Chris on Jan 24th 2026

    Decent hoodie. Pros- Warm, roomie fit but not too big. sits at the hip instead of below your butt like others. Cons- Hood is too small, when sweatshirt is fully zipped and hood up it just about chokes you. Outer material is not as durable as hoped for. Overall good hoodie for a casual jacket but not a work shirt.

    Sizing is spot on for tall people. Glad to see it has a metal zipper. Will buy again.

    Its really good

    Posted by jeremy coffin on Jan 13th 2026

    This thing is fantastic. Very heavy. Very nice heavy thick cuffs and waist band. Nice metal zipper. The hood seems nice and deep as well. This is a keeper. Just FYI......There is no waffle pattern in the hood and the arms are lined with nylon rather than the waffle pattern. I would buy this again in a heartbeat. Its that good.

    Great zippered lined hoodie!

    The weather turned chillier here in the Smokie Mountains this morning. Was comfortable when I took my hound out for walk at 0530. Cut the wind nicely. I’d buy another one for certain!

    Premium Heavyweight Thermal Lined Sweatshirt

    Posted by arlene on Dec 17th 2024

    we live in Mn and raise angus cattle so have to have clothing for our harsh weather we have to go regardless of the temps I ONLY have key products (bibs Montana clothing etc) because of their durability and ability to keep me warm in ALL temps=)

    Insulated Sweatshirt

    Posted by Mike on Feb 2nd 2024

    Nice quality, soft fabric, medium-heavy weight, and warm. The large fits me perfect, including the sleeve length, which seems rare these days (5'9", 185, 44 chest). My one minor criticism is that the zipper is hard to start, since the starter shaft is sewn in a little too far. It's not a deal breaker, and I will definitely buy again.

    Thermal Lined Sweatshirt

    Posted by Bobby on Jan 15th 2024

    I bought the XLR size (5’8” and 180lbs) because I wear a Montana Vest (LR) underneath. Great combination! Lined sleeves make this slip on and off easily. A bit thinner than I expected, but seems well made and definitely worth the sale price I paid. No interior pockets. I’m sure this will become one of my favorites.
