  • Regular price $450.00

The ULTRA35 is a dedicated mountaineering backpack developed with our mountain guide athletes. It is the lightest mountaineering backpack in its class. Its accessorization, waterproofing and durability make it the ideal partner for your mountain tours. The ULTRA35 will accompany you on day trips and multi-day expeditions. Its volume of 35 + 5 litres allows you to leave with all your bivouac equipment while keeping a perfect mobility during your most technical gestures.

The ULTRA35 adapts to all your needs. All the accessories (ice axe holders, helmet holders, ski racks, belts, etc.) are removable. This means that you can prepare your ULTRA35 for your activities from its minimalist weight of 495 grams.

It is the specific technique of combining Dyneema® and polyester (150D) on the body of the ULTRA35 that is responsible for its exceptional resistance to abrasion and its unprecedented waterproofing. On its base, the ULTRA35 is made of a material specifically developed by Samaya® engineers: directly woven Dyneema® 300D fibres provide abrasion and tear resistance so you don't have to worry about anything.

Most of the carrying is done by the shoulders, with a load pick-up and double support at the waist and chest. This way, you become one with your ULTRA35 and have quick and efficient access to all your equipment and your harness. The shoulder straps of the ULTRA35 are made of closed cell foam to provide maximum comfort when loaded. Don't be afraid of long approach walks.
