In reply to random_watcher:
I freely admit I’m probably overly fussy!
My Wishlist is:
55 litres give or take, and 1.5kg or under. Traditional top access bag, I’m undecided if an optional side entry zip is worth the extra failure point.
Light but durable fabric like Dyneema,
Hip belt pockets, lid closure, not roll top, external helmet carrier would be nice
Seperate avi compartment, ideally as a front pocket
2 technical tool carrier, the tunnel and clip style, not just loops.
Side ski A frame carry. Diagonal carry optional as I don’t use one that often.
The closest I’ve come was the Bergen’s Helium Pro, but it’s a disappointingly fragile fabric.
