I've got 5 Maxpedition bags, the Vulture 2, the Malaga Gearslinger, a padded pouch, a larger pouch, and a Octa Versipack. All of them are of exceptional quality and I have had no issues with zips, stitching or whatever. The Malaga Gearslinger has done countless miles on 1 day trips, stuffed to the gunnels and still looks like new, and the vulture 2 has done many walks of up to 120 miles and been a great companion which has been comfortable and well designed for ease of access.
Out of all the forum discussions i have see about maxi gear i have heard the occasional person complaining about stitching, which I think may be down to bad luck, counterfeit gear or maybe I have been lucky? However for every 1 person complaining about the stitching there are hundreds saying the stitching is one of the stronger points about maxi gear. A friend of mine has maxi kit too and has had no problems though so I can only go on the gear we have between us and the stitching holds up better than any other backpack I have seen (for example a friends snugpack is falling apart at the seams)
Pricewise I think their larger bags are very reasonable, at around 100 bucks this is not a lot to spend on something which will last you years and years and is probably going to be the most important bit of kit you own. When compared to bushcraft knifes going for £150 to the ridiculous for a bit of wood n steel I do find it funny that people complain about the price of their packs. However I do find their smaller pouches stupidly expensive in the UK.
Looking at the prices online just now they seem to have gone up a fair bit, but I have never paid list prices for any of the maxi products I have bought and you can usually find bargains on eBay, clearance, sales or whatever.
I'm not a fanatic and I would and do use and buy other makes, but for the quality my opinion is they are virtually unmatched.
Great gear
