Product FAQ

What does “ISO 23537-1:2022 rated” mean?
It means the bag’s temperature ratings are based on a recognised lab test standard—so the numbers are more trustworthy and comparable than marketing-only ratings.Which temperature rating should I use—Comfort or Lower Limit?

• Comfort (5°C): best reference if you sleep cold (often used for women’s ratings).
• Lower Limit (0°C): best reference if you sleep warm (often used for men’s ratings).

What’s the “Extreme” rating?
The Extreme (-14°C) rating is a survival threshold, not a comfort target. For planning trips, focus on Comfort / Lower Limit.What makes this “tactical” compared to a normal sleeping bag?
The integrated armholes, boot-capable footbox, walk/shorten mode, and fast-access two-way centre zip are designed for function and readiness—so you can do tasks without fully exiting the bag (and without bleeding heat).Is it good for Australian conditions?
Yes—Ranger Green for bush/field blending, DWR-treated nylon, and synthetic insulation that performs reliably in variable, damp, and rough conditions.If you want, I can also write a short description (2 lines) + SEO meta description in the same style as the Valhalla listings.
