Pros: tool organization
able to carry my elbow & knee\shin pads + other gear
full-face helmet carrier
velcro around tube (by bite valve) was nice touch to keep it fixated on sternum strap when not in use.
Customer service is great!

Cons: original bladder leaked... (though Lezyne replaced immediately)
now bite valve leaks at the swivel point.
wished it had 'stash' pockets

Recommendation: My Camelbak was great, but I couldn't carry my protective gear on certain rides when I thought I may need 'em. So I scored a Lezyne All Pack off eBay for $30. It's not exactly the same as in the picture here, but the older all-black version. It had the capacity to strap my elbow guards beneath the pack & store my knee\shin pads inside the bag among other things.

The original bladder leaked out of the box. It didn't leak when upright, but when the bag was laid on its back, it did. Emailed Lezyne & they immediately sent out a replacement bladder. I was hesitant about the 'zip-lock' system & expected the replacement to be the same, but was pleasantly surprised how well it actually sealed.

Recently, the bite valve started leaking pretty bad at where it swivels. On a previous crash, I managed to 'pop off' the bite valve from its swivel. Though it snaps back into place, it no longer seals properly.

Also, I noticed that the seams right where the D-Ring for the helmet straps go thru are starting to separate.

All in all, for $30, I can't complain & I still continue to use it as my primary bag. I like that it's different (eveyone on the trails sport Camelbaks) and I like its carrying capacity as well as the tool organization.

However, if I did pay the full price for one of these, I'd probably think differently.

Pros: This is an update to my previous review. Sorry for the delay. I used this pack on the Smith Creek Epic and it performed perfectly. It's holding up well to all the abuse I have put it through. The All Pack is easy to clean, I just throw it in the wash and it comes out looking new. The zippers are tough, watertight and perform as they should.

Cons: The hydration hose tends to leak if you have a full pack, but I have found that biting on the end will release water back into the bladder. This prevents dripping when grinding uphill.

Recommendation: Get this pack if you not only want function, but ruggedness and great looks as well.

Pros: Plenty of water for long rides and a place for just about everything.

Cons: I do wish it had greater storage volume. Using only a 1 liter bladder should help with this.

Recommendation: I have only used the All Pack on short rides so I will have more to report on after this weekend. I would still recommend this product to anyone.
