About the Vango Arctix 400

What is the Vango Arctix 400 Ultralight Down Sleeping Bag good for?

Designed to dominate three-season camping conditions, spring through autumn, this sleeping bag is engineered to tackle temperatures down to 1°C (comfort rating) whilst unleashing performance to -4°C (lower limit) for demanding overnight excursions. Optimised for backpackers, wild campers, and mountain trekkers who demand balanced warmth-to-weight performance without compromising pack space. The Arctix 400 also fuels multi-day expeditions where every gram matters and compressed pack volume becomes essential whilst energising alpine environments and remote camping locations. Furthermore, this sleeping bag thrives in variable mountain weather conditions where moisture resistance proves critical, powering through dewy mornings, light precipitation exposure, and alpine temperature fluctuations whilst maintaining thermal efficiency across extended adventures.

The revolutionary ARC (Advanced Reflective Coating) technology reflects body heat back towards you whilst maintaining breathability and flexibility, boosting thermal efficiency without adding weight. In addition, Hydro Barrier Down treatment keeps premium 750 fill power goose down performing 4x longer than untreated down when exposed to moisture, ensuring consistent warmth during damp conditions. Furthermore, Thermal-Reverb technology radiates body heat through evenly distributed horizontal stitching that locks insulation in place for uniform warmth distribution. The sleeping bag also features a 3D hood with multi-cord closure that creates structured head and shoulder protection, with dual cord thicknesses enabling easy adjustment in darkness during night-time temperature changes.

This product unleashes cutting-edge thermal technology combined with RDS (Responsible Down Standard) certified goose down, ensuring humanely sourced materials deliver ethical performance. Additionally, the integration of moisture-resistant Hydro Barrier coating provides tested reliability in unpredictable mountain environments. Furthermore, the included 3-strap compression stuffsack reduces overall pack weight and volume, whilst Vango's extensive outdoor heritage ensures this sleeping bag tackles real-world backcountry conditions with proven durability.
