My Lowe Alpine rucksack has finally packed it in after 15 years of service and I'm after a replacement. It will be used for alpine-style climbing in the greater ranges, so a 70L-ish volume would be about right.
I'd be thrilled if the new bag could last another 10 to 15 years, but also if it didn't weigh the 3 kg that my Lowe bag weighs. It would be nice if it could be stripped down for summitting, although given the tiny proportion of total time those days represent, a spare construction in its 'complete' state is more important. Nice extras would be ice tool attachments, gear loops, a lid pocket, front mesh or (riggable) elastic cords... and that's about it.
Bags I've had in mind are the Berghaus Expedition Light 80, Mountain Hardwear South Col 70, Lowe Alpine Metanoia 65:80, Aiguille Verte 65+15, Millet Prolighter 60+20 and Black Diamond Mission 75, although I may well be overlooking others. Offerings from Crux (AK70), and CiloGear and Hyperlite Mountain Gear in the States look great, but are out of my budget unless you're collectively convinced that they're really leaps and bounds beyond the others.
Any opinions would be welcome!
