The Nepal Extreme is a men's mountaineering boot from the brand La Sportiva and will be your best ally for glacier outings.
Ideal for high altitude and glaciers, it features an innovative internal lining PrimaLoft® Gold Insulation Eco, which has become a benchmark for thermal insulation. In addition to providing exceptional warmth, it effectively wicks moisture to keep you dry for longer. This boot allows the use of quick-attach crampons.

| PRIMALOFT® GOLD INSULATION ECO | PrimaLoft® is a patented microfiber designed to retain body heat and thus save energy. These ultrafine microfibres are engineered to resist water, so the insulation stays drier for longer and maintains its insulating properties. This synthetic insulation offers excellent breathability, ideal for demanding activities. The performance of Gold Insulation Eco is modelled on PrimaLoft®’s exceptional synthetic insulating power while using 55% recycled polyester fibres. |
| VIBRAM® | Outsole providing excellent traction on mixed surfaces thanks to vulcanised rubber technology, offering high abrasion resistance. |
| IMPACT BRAKE SYSTEM | Innovative system applied to the sole to absorb negative impact on the ground, boost traction when climbing, and improve grip when descending. The unique positioning of the lugs allows most of them to be in contact with the ground, ensuring optimal impact absorption. |
