    For high and cold summit bids.

    The Mammut Men's Nordwand 2.1 High GTX Boot might be overkill for your summer ascent of New Hampshire's Mount Washington, but it'll be the boot you want if you're headed to the Himalayas or venturing up Denali. Mammut's newest alpine boot, the Nordwand is a 2-in-1 super-gaiter boot that boasts a carefully-considered design to maximize warmth, capitalize on comfort, and deliver solid and sure climbing in the world's highest mountain ranges.

    The gaiter of the Nordwand is made with a tough, wear-resistant material to handle the wear and tear intrinsic to climbing alpine ice and rock, and it's reinforced with a full-wrap rubber rand for additional protection from the rugged alpine environments the Nordwand was built for. A waterproof and breathable Gore-Tex membrane works in concert with fully taped seams and waterproof YKK zipper to ensure your feet stay dry in environments where contact with moisture could be costly. Mammut even added its Chimney ventilation system to help ensure good breathability and limit sweat accumulation. The inner boot is insulated with Thinsulate Ultra insulation, making the boot capable of keeping your foot warm in temperatures down to -31 degrees Fahrenheit.

    Mammut designed the Nordwand 2.1 around its Easy Entry System, which allows the boot to be taken on and off with gloves on, so you don't have to expose your fingers to the cold after an already cold day on the ropes. Ensuring a secure and comfortable fit, the inner boot houses a wide hook-and-loop power strap, Boa closure system, and drawcord lace closure. The inner boot is composed of a synthetic leather, which is nearly identical to traditional nubuck leather, except lighter. Mammut's patented carbon insole is double insulated for increased warmth and sits above a stiff, light, and compressed Poro wedge midsole and Vibram Teton sole for a good dampening properties and climbing feel that's hard to beat.

    Nice boot overall

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 12
    • Height: 5'11"
    • Weight: 195lbs

    Upgrading from a plastic double boot these were much more comfortable and flexible. Two climbs of Mt. Katahdin on back to back days around 0°F they kept my temperature regulated and unblistered. Hoping to put them on some vertical ice and see how they do. I wear 11.5 to 12 and the 12 gives me plenty of room. Wide toe box! I have wide feet and these fit fantastic.
    Only reason I didnt rate 5 stars is the fact that after one 4 day trip the rubber covering the zippers on both boots is starting to separate where the boot flexes. Also the outer layer on the seam tape in the built in gaiter is starting to rub off a little by the BOA closure (the BOA is incredible, doesnt loosen up at all)

    Hopefully backcountry will let me know if mammut has had any zipper trouble after reading this review.

    Very bad experience in Aconcagua

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 9
    • Height: 5'7"
    • Weight: 154lbs

    I bought this boots on July 2017. Nice, comfortable and warm boots.
    On February 2019 I went to Aconcagua, and on the summit day, the zipper broke.
    Very bad experience with a freezing climate.

    Unanswered Question

    Does anyone have any thoughts on how warm this boot would be compared to either the La Sportiva G2 SM, or Spantik?
