At Aristarun, you will find specialized technical advice to choose the right version.
Below, we present the main ranges available and the 8000 variants for Men's Trekking + at Aristarun.
Designed for trail runners facing low temperatures at mid-altitudes, this variant combines high-insulation down filling with an ultra-light shell. It incorporates 8000's proprietary technology aimed at minimizing pack volume without losing heat, and chamber distributions that prevent down migration. The result is an optimal balance between warmth, weight, and freedom of movement on rapid ascents.
Targeted at more sustained running paces and longer distances, with reduced weight and excellent compressibility for storage in a belt or 30–40 L backpack. The 8000 technology optimizes moisture management and active ventilation without losing heat retention, with snug cuffs and a sealed hem that reduce cold air intake during descents and windy sections.
Version with an integrated hood and high collar for stormy conditions and icy winds. It features a double-layer construction in the neck area and quick-access pockets, maintaining warmth without compromising mobility on zig-zag stretches and challenging mountain passes.
The 8000 jackets excel in their balance of insulation, weight, and compressibility for prolonged expeditions. Their proprietary technologies optimize warmth without inflating the pack, suitable for trail outings in extreme cold and high VO2max phases during continuous ascents.
For trail runners and high mountain expeditionists who demand consistent warmth with a contained weight. Its insulation range and moisture management allow efficiency in cadence and performance during prolonged ascents.
The differentiation is based on 8000's proprietary technologies, an optimized heat-to-weight ratio, and optimal moisture management thanks to DWR and selective ventilation. All of this translates to greater compressibility and sustained thermal performance in extreme cold conditions.
