Why We Like The Mystery Ranch Coulee 40L Backpack
Comfort and convenience come together in the Mystery Ranch Coulee 40 Backpack. Whether you're gearing up for an all-day hike in the hills or keeping things light for a quick overnighter, this ingeniously designed bag has your back.
It features an innovative 3-ZIP design that allows us to gain access to the entire main compartment at once. That means no more digging through all our gear just to find an elusive headlamp or hidden camp meal. A lightweight fiberglass frame adds support without the weight when we're hauling a full load into the wild, and the telescoping yoke provides a custom fit that most packs in this size range can't offer.

Awesome pack
Excellent pack for winter hikes or summer overnights. Futura harness for the win.

1 step from perfect….
- Familiarity:
- I've used it once or twice and have initial impressions
If waist belt was detachable, it would be less cumbersome for airplane travel as I bought it for. Pouches on belt great for access of keys & small items but waistband less necessary if not used fr going. Great versatility & construction nonetheless.

Good pack with a fatal flaw
The good: robust fabrics; the zipper system (love it), the adjustable harness The soso: ventilated backs make a lot of difference in hot climates, and the Coulee is NOT a cool pack (no MR pack is); if the center zipper ran another 3 inches closer to the bottom of the main compartment I may have been willing to look more kindly on the fatal flaw (below) The bad and the ugly: why does a 40L pack frame need to be 24 inches tall? So it makes your life miserable when you fly with it? MR could have easily shaved 2 inches off the height and increased the width by an inch to hit the volume target and kept it 100% carry-on compliant. At 24" tall you roll the dice every time you board. I would have used it to carry photo gear but can't take the risk of being asked to check it I wanted to love it but can't.

Perfect all the way around.....
Great product all around; a friend and I each bought one, and I purchased a different style for my son for hiking & scouting... I will never buy anything but Mystery Ranch; the quality is different!

What is best sized hydration bladder (not volumn) dimension wise for Coulee 40

All of a sudden, Mystery Ranch isn't including whether or not packs have a place for hydration bladders and tube ports. So does it? I assume it must, as my old Coulee 25 does.

Does the bag have any sort of divider between the main compartment and the sleeping bag compartment? Similar to the coulee 50?

Is the waistbelt on the Coulee 40 removable? The description says it is, but I watched a review that said it was not removable on the 40, only the 30
