Ed - How long have you been using your Aiguille sacks? What does your longest serving Aiguille sack look like? Do they last / wear well? I just want to know as too late now to backout of getting mine.
My oldest sac is about 11 years old and looks like new - however, it get very little use as its a bit 75l+ jobbie.
I had a Triolet for a number of years - I gave it to my mate and it is still going strong. Must about 10 years old now.
Mymost used sac is a Super Couloir and is has had some hammer. It about 7 years old and until the end of last year it was my main sac for everything. - i've now got a couple of smaller Haglof sacs for summer / less gear trips. However, for serious stuff it is still the one I go for.
It has been used for walking, climbing, winter climbing, year round bivvying and mountain rescue stuff. It has been worn, sat on, thrown to the ground in rough wet place far too often. Thrown around crags, dropped down caves, bounced in Sea Kings, chucked in and out of far too many Land Rovers (my cars for the lat number of years are diry old Solihull machines) and seriously over filled. It had also jsut returned from a 3 week holiday around central America (unfortunately without me).
It is still 100% usable. Actually, more than usable. It is dirty and a little scuffed but not baddly, just nicely broken in. The only holes or problems are where I left a cereal bar in the top pocket and a mouse chewed its way through and Aguille repair patched this for me for free.
Should get another 10 years of abusse out of it.
They are not the lightest of sacs but they are bombproof and very comfy to wear. I would say that once you have one you'll get another one but its unlikely to wear before you do so you'll not need to repalce it.
I'd certainly get another one. The after service / reapir etc if needed is worth the bit extra if nothing else.
