The TORAY Airtastic fabric is not only durable but also water-repellent, protecting the down from moisture.

Recommendations

For optimal performance, store the sleeping bag uncompressed in a dry place when not in use. Use a compression sack only during trips to preserve loft. Pair with a suitable sleeping pad to maximize insulation from the ground. The bag's DWR treatment helps repel light moisture, but avoid prolonged exposure to rain. For users taller than 180 cm, consider the longer version if available.
