Salewa Ortles Guide 45 £170

This robust pack is built from high-tenacity double ripstop nylon, with a reinforced base. The fabric is 100% recycled too. But as well as being tough, it’s lightweight and weatherproof.

There’s a roll-top closure beneath a floating, double buckle lid. The lid can be removed to save weight. That would mean losing the lid pocket, but there is a secondary zipped top pocket with a key clip inside, plus a large, zipped front pocket.

The main compartment has a two-way, water-resistant side zip for quickly grabbing or stowing an extra layer. It’s also hydrationcompatible, with other features like side compression straps, a rope strap, ice tool/trekking pole loops and ski holders.

It feels stable when loaded, with a plastic framesheet and a U-shaped metal stay to add structure and rigidity. But the most striking design elements are the harness and back system, which feature split shoulder straps and a heavily vented ‘Dry Back Contact’ panel. It’s a good weight-saver and makes for great airflow.

As such, you could use this pack year-round, which adds to its overall value (especially given that it’s widely available for around £150). On the other hand, we do think the design entails a few compromises.

IF WE’RE BEING FUSSY

The floating hip fins aren’t the most supportive. We found that the split straps tend to fold over when you’re getting the pack on and off, while for winter use the vented back panel gets chilly and accumulates snow and ice. This pack only comes in one size too.

■ WEIGHT 1.38kg (0.95kg stripped)

Verdict

A technical pack that is tough yet light, and versatile enough for year-round use. But the harness and back system won’t suit all.
