DCwrote a review of Mountain Hardwear BMG 105 Backpack - 6400-7000cu in on June 26, 2012
This pack has served me well over the last 2 years. Has stood up to everything i have thrown at it.
The fit is great right out of the box. The hip belt takes a couple of miles to adjust to. (most packs i have used need a little breaking in)
I have had 70+ lbs in this pack and it carried well. I can fit my 4 season North Face tent along with a -30 sleeping bag, food for a week, Emergency gear, and all my clothing and gear for sub 0 degree weather.
The pack doubles great for hauling climbing gear during the summer and I find myself using it for shorter summer treks just for the ease of use and option to carry that extra bit of gear to make life more enjoyable on the trail.
The expandable top section compresses nicely for shorter trips.
And like mentioned the pack does have a hydration pouch. With a loop for clipping on compatible bladders.
And if you have not worked with Mountain Hardwear on warranties they are amazing. Sent in an old tent with broken poles and a destroyed rain fly and was given new poles and fly and all i payed was shipping.
Great company to work with and always amazing products.
