I want to buy a versatile pack that will handle such thing like one month mountaineering course, two week long skiing training, and 1-6 days hiking/cycling/skiing trips. I am no ultralighter but I pack minimal.
I after some research I narrowed down my choices to:
GG Vapor Trail
Gregor Z pack
I even liked ULA Conduit/Circuit &
SMD Comet/Starlight but they are outside my budget so I am not cosidering them right now, unless somebody here put out used ones for sale.
The things I considered are:
>cost/volume-weight:I have modest budget of $120.
Z55 pack Medium is going to cost me $125.
Weight: 3 lbs. 10 oz. / 1.5 kg
Volume: 3300 cubic inches / 55 liters
(note: Gregory pingora will cost me $118. But at 5 lbs. 6 oz. it leaves no room for consideration.)
Vapur trail Regular will cost me $90.
Weight: 2 lbs 0 oz
Volume: 3600 cu in
>Durability (material used):
Z55 Pack-
210D HT "double box" ripstop nylon
210D HT nylon twill
GG Vapor trail-
70D Cordural SilNylon ripstop, 210D woven Cordura, Schoeller Dynamic
It is quite a technical subject, but I think Z pack is more durable. Correct me if I am wrong.
>load Carry capacity
I think the comfort level of both is 30lbs and Z pack has much better ventilation and suspension.

But after reading shawn review on z55-
"The pack's suspension proved to be finicky. The large bow in the back panel means I only achieved small areas of contact. Unfortunately, this resulted in undue pressure in the lower back (initially), followed my a downward sag, which resulted in increasing shoulder contact and fatigue.
Making the situation worse was the sternum strap. If it had held securely, it would have placed more support on my chest, which I far prefer to my shoulders. But the strap kept sliding upward until it eventually reached my throat, requiring me to stop and push the strap back down to my sternum."
-I am having second thoughts. I am quite thin at waist:30, chest:35, so I don't know how Z55 will work for me.
Thats what I ve come up with so far, if you have know of some other pack which will serve my needs better, any recomendations, anything, please tell me.
