The technical high mountain boot is the new reference for expeditions to 8000m peaks, but also for arctic crossings and extreme missions in very cold environments. Extreme lightness, low volume, precise and comfortable fit and maximum freedom of movement. Developed and tested in collaboration with extreme mountaineer Nirmal Purjia during his winter ascent of K2.

• The first expedition boot with integrated thermal system
• The only 100% waterproof high mountain boot
• Discoverable thanks to RECCO reflector - more safety
• GAITER:
  - 8000 GAITER The wide gaiter with adjustable closure is made from S-TECH Schoeller, manufactured from sustainable material base that is PFC-free and BluesignTM certified. Waterproof thanks to YKK® zip and sealed reflective tape for protection.
  - THERMIC SYSTEM The thermal system is integrated into the inner sole of the Geamasche (weight 160g): One power regulator for 3 modes (16 hours - 8 hours - 4 hours). Two power banks with plug and charging cable to be stored in the pocket provided. A pair of additional heated insoles covered with microfibre to increase comfort and durability.
• INSOLATION
  Carbon Tech 3 SL, made of three layers: the first in perforated EVA for maximum comfort, the second in Aerogel® for maximum thermal insulation and the third in carbon fibre for maximum stability and lightness.
• EXTERNAL SHELL
  Shell 8000
  The shell consists of different layers
  - water-repellent microfibre with high mechanical strength: 50% recycled nylon from the primary material, 50% PU.
  - an insulating felt and aluminium foil and WinTherm made of 80% recycled PET for active thermal insulation.
  - Micropile and EVA + cork.
  - PVC structure in the EXOSKELETT for better protection and grip.
  The RECCO reflector makes you discoverable in emergency situations.
