Scarpa Phantom 8000 HD Thermic B3 Boots

The Scarpa Phantom 8000 HD Thermic is an industry leading, high-altitude B3 rated mountaineering boot. Made in collaboration with Nirmal Purja, choose for expeditions on 8000-metre peaks, arctic crossings, and extreme winter environments. It is the first mountaineering boot with an integrated thermal system. The Therm-ic 3D heated insole uses Thermo Transfer Technology to help you stay warm in the coldest places on earth.

The boot construction comprises a durable and protective outer boot, an insulated inner boot, and a removable liner boot. The external gaiter features a waterproof HDry membrane, abrasion-resistant PU Tek Technology, and PrimaLoft Gold insulation to seal in heat. It also has a 100% waterproof zip with an offset design for easier access while wearing gloves.

The inner boot contains WinTherm technology, which provides a secondary insulation layer. The Sock-Fit XT tongue combined with the Power Strap Lite Velcro strap and fast lock lace system makes it easy to get a precise fit with no pressure points. The removable liner boot features an adjustable side closure plus two pull tabs to aid donning. Inside, there are two insole options. You can use the OrthoLite O-Therm insole with Aerogel insulation or the Therm-ic 3D heated insole.

The Therm-ic 3D heated insole has three heat modes to adapt to your needs. The technology maintains optimal foot temperature, improving comfort and performance in sub-zero temperatures. A Therm-ic Slim Universal power bank powers the insole and is USB rechargeable. A power button at the top of the gaiter makes it easy to turn the insoles on or off.

The boot's base unit includes lateral and medial support for front pointing, step-kicking, and traversing. A Vibram 0 Gravity Lite outsole achieves superb traction for confidence in each step. A RECCO reflector makes the wearer more searchable, increasing safety in mountain environments.
