Akona uhh......
I got 5 Akona bags:
2 regulator bags (similar to AKB604)
1 large regulator bag (similar to AKB615)
1 backpack (similar to AKB154) (big one for diving, not treking)
1 Dive bag w/o wheels (similar to AKB114)
The regulatorbags where used on every dive trip for more than 6 yrs and don't show wear at all, just a few stains and that's all
The large regulator bag is the size of a briefcase and is my main weekend travel bag, has gone all over the US as a carryon and looks brand new after 6 yrs of use. This bag has the option of being used as a back pack, can be carried as a briefcase and has a shoulder strap.
The Big back pack has been used a couple of times, not abused like the other bags, but the construction of the bag is similar to the other bags and has multiple handles all over it.
Tha dive bag has multiple handles around it, can be used as a back pack, it has carried 2 full scuba gear sets in many dive trips. This bag has been abused for the last 8yrs and has multiple stains from the diferent boat fluids. Now is starting to show some wear at the bottom of the bag, at this rate, the bag may tear at the bottom in the next 5 yrs or so. This bag is bullet proof and can handle anything that I throw at it, now with the new Pelican 1620 it will get some rest (I'm tired of lugging the gear around in my back, I'll now roll it and save my back)
In fact I'm a big Akona fan and it's the best bag manufacturer I've come across.
Not sure about the last and this yr models, the materials used now are diferent from the balistic nylons in all the models I own, but since these people have a good track record with me, I don't see why the newer materials should be of lesser quality, I may need to buy one of the newer bags just to try this new materials.
