It's a day pack for big objectives or a svelte overnighter.

This 3-ZIP day pack offers quick access. Featuring a suite of exterior, stretch woven pockets – two on the front and two (water-bottle-ready) on the sides – the new COULEE 40 is all about grab and go convenience. Designed with dual composite frame stays for stability, the fully adjustable yoke affords a customized fit.

  • This mainframe is comprised of two vertical composite rods and an upper horizontal composite bar. The composite cross stay keeps the vertical rods properly aligned and allows them to pivot and flex for a dynamic, stable carry. There are two upper portions and one lower of an HDPE frame sheet for added structure. Through patented features and construction methods, the mainframe transfers the weight of the load into the wings which relay the weight and equalizes the contact around and into the belt. The waist belt cants and conforms over the hips to effectively transfer and distribute the weight and eliminate slippage down over the hips.
  • The patented Futura Yoke easily micro adjusts to the torso length allowing the proper amount of stand-off between the back and frame.
  • Features a removable waist belt system.
  • Featuring our classic 3-ZIP design for easy, rapid access to the interior.
  • Front and side stretch woven pockets on exterior
  • Two zippered compartments in lid to organize essentials
  • Two tool carry loops with secure straps
  • Side compression straps for load stabilization and lash on options
  • Fully cushioned, contoured waist belt with zippered pockets
  • Hydration reservoir compatible
  • 330D Robic nylon fabric
  • YKK® zippers

Rated 5 out of 5 by from The right size and fitI was having trouble finding a tri zip that would be able to be a carry on, roomy enough AND fit me. I am 6’2” w a very long torso (32” inseam) and am rather stout (46” chest and 244lbs) The scree large frame fit me but the pack itself hung way too low when the frame was adjusted. It was also a bit small at 32l. The coulee 40 is a great fit, super comfy and the outside stretch pockets are great. Also, huge bonus, the waist belt not only has larger useful pockets on it (scree way too small) it is removable. This is nice when you don’t need to carry a heavy load and want to be a bit more nimble. I have trained with 35-40lbs in the pack (waistbelt on) and it is very comfortable. Most ever actually

Rated 5 out of 5 by from Really Great PackI bought this pack about 3 weeks ago and have done some short hikes with it and it is great! I like that you can dial the pack extremely well to your height also I'm 6' 3" and had no problems getting the Lg/XL pack dialed in to fit me. the quality of this pack is excellent to. I really like the zippers and I also like the 3-zipper system for opening/closing the pack. It makes it easier to get what I want in the main compartment.I have had a lot of packs in my lifetime and this one really sticks out as an excellent one. I believe I've found my go-to pack for day trips and also for an overnight hike.

Rated 5 out of 5 by from This is “The Pack” if your over 6’ tall!I had been looking for a bag that actually fit on my 6’5” frame for years...the mystery is over! Finally a bag that actually rides on my hips correctly thanks to the “Large” size option! The Mystery Coulee 40” is the answer! Great fit, construction and fantastic shoulder and waist padding makes for a great day on the trail. This is the bag! Mystery solved! Buy it!

Rated 4 out of 5 by from Wish a smaller hip belt was available.As with other MR packs, the craftsmanship is fantastic. This pack is beautiful, and the size is just about perfect. However, the hip belt is just huge. I'm not a really big guy, but the hip belt just about overlaps my waist. I'm 5'7 with and usually wear a size 28 pant (sometimes I need a belt). I realize that they have to build these pack to accommodate the big guys with the 40 inch waists. But what about us little guys? The larger size packs have an XS belt option. Why not these mid size packs?

Rated 5 out of 5 by from All about the carry....This pack gets everything right. As an landscape photographer I usually have about 30 lbs in my daypack between lenses, cameras, filters, tripods, as well as my regular hiking needs and Im usually out dawn to dusk when I go - so for me, a pack is first and foremost about the carry. Great organization means nothing if your shoulders and back are wrecked. Bottom line: This is now my go to day pack for photography. First hike with the Coulee 40 was 13.4 miles at altitude (9-11K) with about 3800ft of elevation gain to the summit in under 7 miles - A big pants hike for sure. The Coulee was spot on - no neck or should fatigue at all, the weight clearly near the hips, the shoulder and hip belts are well padded, ventilation is good. The organization of the pack is also sneaky good - the 2 water bottle pockets are deep and cinch easy, the 2 lid-pockets are ample for what they carry, and most surprising is how much I love the dual front kangaroo-style pouches. I always think having a big mesh kangaroo style is useful and was doubtful about having 2 small ones instead - but they are bigger than they look and I found them useful for organizing. Ive obnly had the pack a week and 13 miles on it, so durability is TBD - but it looks like it will handle a beating. But again - 5 stars and FULL recommendation based primarily on the super carry capacity and the organization just adds a cherry to the top. Get sized right, fit the pack right, and then just enjoy the ride - because its that easy with this thing.

Rated 5 out of 5 by from Great trail pack with Mystery Ranch ToughnessThe Coulee 40 is a great all around pack for hiking and short overnights. It has a fantastic suspension system which is not surprising given its Mystery Ranch lineage. The shoulder straps, sternum strap and hip belt all have a wide range of adjustments to fit a variety of body shapes. The rear stretch pockets are generously sized and usefully placed. I've been looking for a 40 liter pack for a while and this one is just about perfect.

Rated 5 out of 5 by from Love this Pack!I have the previous version of this pack and have been using it for about a year. I am a SAR member and use this as my 24 hour pack. It is extremely comfortable under load and very durable. I love the three zip design and the how it gives access to the entire main compartment packing and offer quick access when emergency items/gear are needed. It is definitely large enough for shorter backpacking trips as well.

Rated 5 out of 5 by from Outstanding Pack!Perfect size, perfect fit. As a large frame guy, I was surprised by how well I could dial in a fit that was comfortable and carries so well. The pack overall is well made and I think it will last a long time. I use this as a day pack and have plenty of room for my day load out. The stuff pockets are stretchy and I was surprised by how much they can hold. I like this packs build and features so much, I bought its big brother the 60L sphinx for overnighters. I am very happy with my purchase!
