I just purchased this great pack but...
I just purchased this great pack but unfortunately, the water bladder (Nalgene CXC Rapid Fill, Get-A-Grip) I already had does not fit into the hydration pocket when completely filled. I was wondering which water bladders are compatible with the designated hydration pocket.
I've used my old camelback 100oz, and it can just fit. It's tight when it's full. I think the reservoirs with less structure fit best.
Hmm, Brandon, curious becuase I could not fit the Camelbak. Not a single 3 liter (100 oz) bladder fit. I also tried all my Platypus bladders, my Osprey bladders, and a Nalgene bladder. The ONLY bladder that fits in my Altra is the Platypus 2 liter with the small mouth spout. ArcTeryx should sell the pack with this bladder included.
I got the Source Widepack to fit. 3l 100oz
wasn't right for me
I recently purchased this pack and really wanted to love it, after all I was willing to pay $375 for it. The pack just was not a comfortable fit for me. I am 5'5 and 125 lbs and no matter what adjustments I made I couldn't make it ride well. It may fit somebody else perfectly.
Pros: Front access makes getting to gear really easy without messing up the rest of your pack and hip belt had a lot of cushioning
Cons: Tiny hydration compartment which is located on the side of the pack in a zipper compartment which I thought could make for tough load balancing, the pivoting hip belt squeaked (probably just needed grease)
All in all if the pack were comfortable for me I probably would have kept it but still wasn't as great as I expected from the reviews I have read from magazines and other websites.
Is this pack waterproof?
Is this pack waterproof?
No, the siliconized and PU coated shell materials give it pretty good water repellency, but it's not waterproof.
Arc'teryx makes a series of truly waterproof packs-check out the Maia (w's specific) and Naos packs. The Altra is very water resistant, but if it's pouring, you'll want a pack cover to assure dryness, as the seams and zippers may let a bit of moisture in.
No, it's not waterproof and two of the four zippers leak. The pack cloth is very water resistant. But count on using waterproof stuff sacks for those items that can't get wet. The pack cover sold by ArcTeryx is 9 oz. You can save substantial weight by using waterproof stuff sacks.
does this pack have a sleepingbag...
does this pack have a sleepingbag compartment?
No, it does not have a separate sleeping bag compartment.
The Altra has a U-shaped opening which makes sleeping bag (and everything else) easy to access, but it doesn't separate you bag like traditional designs.
