The Mammut Eiger Nordwand Pro HS Pants are the ultimate choice for professional alpinists, mountaineers, and committed climbers who demand maximum protection and performance in extreme conditions. Designed as the flagship model of Mammut's legendary Eiger Nordwand collection celebrating 30 years of innovation in 2025 these hardshell pants have been refined through athlete testing on the most demanding ascents. Constructed from highly durable 3-layer GORE-TEX Pro fabric with a PFC-free ePE membrane, they deliver complete waterproof, windproof, and breathable performance while maintaining exceptional abrasion resistance. The pants feature a 100% recycled nylon face fabric and solution dyed backer, drastically reducing water consumption in production. Built with a sustainable, repairable design ethos, the Eiger Nordwand Pro HS Pants combine uncompromising performance with a reduced environmental footprint.

GORE-TEX ePE is a totally PFC free waterproof membrane designed by Gore to be more sustainable and cut out harmful long chain 'forever chemicals' found in normal PTFE waterproof membranes. The ePE membrane is a thinner than standard GORE-TEX and GORE-TEX PRO, which results in a softer and more supple feel. It doesn't have the same stiff 'cardboardy' feel as older Gore membranes. The biggest perfromance difference you are most likely to notice is the DWR treatment. Unfortunately flurocarbons are some of the best, most hydrophobic chemicals out there. Getting rid of them does hit performance so you will notice that the nice 'beading' effect disappears quite quickly. Don't worry your GORE-TEX ePE jacket is still waterproof, but to maintain the beading effect you will need to top up the DWR more regularly.

Packed with technical features for alpine specialists, the Mammut Eiger Nordwand Pro HS Pants ensure absolute reliability in harsh environments. A climbing-specific pattern and articulated fit provide complete freedom of movement, while strategically reinforced seams enhance durability under heavy use. Practical details include adjustable, removable suspenders, a high rear waistband for added protection, and dual-sided hook-and-loop waist tabs engineered for easy adjustment with gloves. Ventilation is provided via 2-way, 3/4-length water-repellent YKK AquaGuard zips, complemented by harness-compatible pockets for secure storage. Lower leg adjustments and Dyneema-reinforced crampon guards deliver superior boot integration and abrasion resistance, with fully adjustable internal gaiters to seal out snow and ice. Finished with an integrated RECCO reflector for improved searchability in emergencies, these pants are supplied with a repair kit for field fixes making them a rugged, functional, and dependable partner for serious alpine missions.
