A climbing pack for long days at the crag
Sport climbing has a habit of turning into an all-day mission – route after route, shoes on and off, chalk everywhere – and the Affinity 42 is built around exactly that chaos. It's roomy enough for a full day's kit, and the roll-top adds another 10 litres of extra capacity when you inevitably bring too much. A rear zip gets you into the main compartment without unpacking everything from the top, while four compression straps, a daisy chain and two material loops give you plenty of ways to lash on extra gear. There's a dedicated pocket for climbing shoes and chalk so they don't end up mixed in with your lunch, and the load control cords double as an external rope fastening for the walk-in. Robust materials and a padded back panel mean it'll take the abuse of scrambling around at the base of a rockface, and it's stable enough to double as hand luggage for your next climbing trip abroad.

If you've spent much time in the Alps, chances are you've seen a lot of folk sporting Ortovox kit. It's one of the biggest and most well-respected brands in Austria and Germany, backed up by the kind of mountain heritage that most companies can only dream of.
Ortovox started out more than 40 years ago making avalanche transceivers and other rescue equipment, and to this day they're still the go-to outfitters for mountain rescue teams, alpine guides and extreme mountaineers. Get your hands on an Ortovox pack or garment and you'll soon see why. The construction and quality of this stuff is on a whole different level, right down to tiny details like the buckles and merino mesh inserts. It's gear you can rely on day-in, day-out, in seriously spicy conditions – and thousands of mountain professionals genuinely do just that.
Ortovox kit has a very distinctive, technical look – and their background in mountain safety means they're big on bright colours that make you easy to spot in an emergency. But the materials bear closer inspection too. They're huge champions of the properties of natural wool, and they've been using it in performance mountain gear since the 80s – putting them streets ahead of other manufacturers who are only just rediscovering nature's original miracle fibre. As a bonus, this also makes their products very environmentally friendly, and the entire winter range is now climate neutral.
