This is Mountain Equipment's latest pack designed primarily for rock/ice/alpine routes, which took them a long time to develop (testing with mountain guides etc.) and is made with premium materials. Please refer to their website for a better description (and better pictures) than I can give:
This pack was used once -- and never got anywhere near rock! It is effectively as-new with no signs of wear.
I have wrapped some double-sided velco tabs onto the straps to keep the loose ends under control.
Costs $300 new here in the US, at Campsaver.
Very happy to answer questions and send more photos if needed.
