Retail price: £75 on Ebay, £85 at Heinnie Haynes, price varies between the two.
Build quality is excellent, very durable 1000D Cordura. Epic stitching.
Main pouch is actually big enough to fit an FM12 respirator with filter attached AND a spare, just tested it for this, although its not what I usually carry in there. Has a pouch for carrying a 1L bottle, although if you don't mind it sticking out the top I believe it will take a 1.5L or even 2L at a push pop bottle (y'know, like coke and stuff comes in). Has plenty of useful pouches, I especially like the one atop the lid, as it perfectly fits my maglite and four or five glowsticks. There's a very handy sheath at the side opposite the bottle carrier which will quite happily accept a survival knife, although I keep my sharpies in it. plenty of Molle style attachment points dotted around it, I've stuck my pocket organiser and a folding dump pouch on them in the pic above, as well as a climbing grade karibiner just out of sight in the photo above.
Its extremely comfortable to carry, plenty of padding, shoulder strap comes with a detachable padding, and if you need to do a lot of activities and don't want it banging about or swinging into things and getting tangled, there's a detatchable waist belt.
Come in various colours, including OG, khaki, black, and random assorted icky colours like....orange...ewwww...
Definitely beats having everything bouncing about in my pockets everywhere!
) as at the moment I just tend to have stuff in pockets if i'm wandering up to the shops etc. I have bags in the car and bags at home but nothing really for the inbetween bits other than pockets.
