Carryology reports a drawcord closure that works with thick gloves, alongside small front and internal storage for quick-reach essentials. The reviewer found the liner useful for keeping dry clothing and food apart from wet hardware, effectively creating two carry zones. Front-mounted ice tools and crampons were described as secure yet quick to release.
Reported comfort depends strongly on load and trip type. Carryology considered it comfortable below 16-18kg, but at about 22-24kg the reviewer wanted more supportive straps. A fully extended liner can also make lifting and wearing the pack harder. Minimal features, a thin hip belt, a potentially flimsy front cord, and pockets restricted by a full load are the stated compromises.
Reported strengths
- Comfortable under 16-18kg, according to the reviewer.
- Drawcord closure is easy to use with thick gloves.
- Roll-top liner can separate dry items from wet hardware.
Reported trade-offs
- Support was less satisfactory at about 22-24kg.
- The front drawcord felt flimsy after a few uses.
- Internal and external pockets become difficult to use at maximum load.
Scope and limits
- Historical publisher sample only; present production equivalence, stock and individual fit have not been confirmed.
- This is an attributed analysis of one original publisher review, not a multi-publisher roundup or a CarryFacts hands-on test.
