At Aristarun you will find a technical catalog of Sleeping Bags geared toward mountain runners who demand performance in cold and reduced weight to maintain inertia on ascents and aid recovery on descents. This catalog brings together models with different fillings, comfort temperatures and fabric weights to sustain a high VO2max during training mileage at altitude. As a specialized store in trail, trekking and climbing, we offer fit guidance, compatibility with hydration backpacks and field-tested selection to maximize the efficiency of your stride and the kinematics of your descents. Explore options with reliable insulation and water-repellent treatments for long expeditions.
The Sleeping Bags represent a specific variant within our Trekking Accessories family, designed for resting insulation and to optimize energy management during long hikes. Below are the options related to their differences:
The poles do not provide insulation; they differ in propulsion dynamics and load distribution during ascents and descents. Link to Nordic Walking Poles
Head protection and surface temperature management influence the conservation of body heat during technical pauses at altitude. Link to Trekking Caps
Beanies add an extra layer of insulation to maintain temperature during micro-descents and rest stops, differing in weight and lining from caps. Link to Trekking Beanies
They protect hands from wind and cold, with variations in filling and grip for light climbing and technical descents. Link to Trekking Gloves
Trekking Poles increase stability and stride control on mixed terrain, differentiating from sleeping bags by their support function rather than insulation. Link to Trekking Poles
For an experienced runner, these criteria directly influence thermal efficiency, volume and reliability on multi-day expeditions:
Choose a model with a use temperature below the expected temperature and a fill that maintains loft when damp. Prioritize a weight suitable for your training mileage and a reasonable packed volume for mobile shelters.
Down offers a higher warmth-to-weight ratio and compressibility, ideal for cold climates and multi-day routes, while synthetic retains heat better when wet and is easier to dry, at the cost of greater weight and volume.
