Product Description

The Mystery Ranch Pop Up 38 Pack is a versatile pack ideal for hunting and hiking. This Mystery Ranch pack has a unique Pop-Up Frame that allows the pack to convert between a low-profile pack for day trips and an expanded pack that can carry loads up to 80 lbs. Dual side pockets provide accessible storage for water bottles, trekking poles, tripods, and rifles, while a compressible back pocket provides accessible storage ideal for spotting scopes or extra layers of clothing. Plus, the Pop-Up 38 pack has an OVERLOAD® feature that uses a load sling to keep the bulk of the weight closest to your back for optimal comfort. Built for versatility, the Mystery Ranch Pop Up 38 Pack easily converts from a daypack to a load-hauling system for tough days in the backcountry.

Pop up 38
Just purchased the 38 after have by the 28 for a few years. Both are extremely well built and were exactly what I was looking for in a pack.

Happy I decided to go with the Pop up 38
I wanted to go with the pop up 28 for minimalist archery pack, but after deciding to pull the trigger on the 38, I would of not have been happy with the 28. After putting the Zoid Cell and it as well as the hydrapak, a coat and some other gear, there wasn't much room left. Couldn't have been happier with the pop up 38.

Great storage.
Bag fits everything I need, comfortably. I love the sustainment pouches being on top as opposed to the sides of the bag. I can use it for hiking and works as a carry on for flying.

Will haul large elk
I hauled a 330" elk bull head and cape 3 miles through deadfall... We weighed it at 90 lbs... so the total load on the frame was probably 100 lbs. Pack handled it just fine. It does kinda suck that the bag doesn't cinch close to the frame when it's half full. But that's the only weakness if this pack.

Great design
Lightweight, durable, super comfortable and adjustable. The ONLY improvement would be some molle webbing for attaching some pouches, but that's a minor inconvenience. The design and overall quality far outweigh the lack of moly attachments. Great pack!

Well thought out
I bought this pack to use for saddle hunting in hard to get to areas where I will be sitting for a whole day. In wisconsin that may be in 65 degrees or 10 degrees, which makes clothing difficult to manage when crossing miles of swamp or hills. This pack has the storage required for long day sits, adding and shedding layers depending on conditions, and packing meat out on successful days. It makes all my hunts better. More storage than the other pack options with a more rigid Frame allowing for meat transportation as well as gear. Truly an innovation to the market meeting a demand that customers had. You can carry 4 or 5 sticks, platform and all while still being comfortable. Id suggest this pack over any I've used, even if only for short sits where your requiring zero extra gear, it still fits that bill and is not excessive. A true hybrid that crosses multiple markets and multiple demands and most importantly does it exceptionally.

Honest Review
I have had the pop-up 38 out on about half a dozen hikes now and am developing some opinions.
Out Of The Box: construction, design, and quality seemed to be what I expected of Mystery Ranch, top notch, but would be nice with hip pockets (that you didn't have to buy after, and somewhere to lash my bow to. Lastly, as many other reviews note, the main compartment has a bit of slack between it and the frame. I wrapped the top staps around the pop-up bar and this helped a bit. I think one other adjustment that may help would be to make the material on the back pouch a bit narrower thus giving more webbing to cinch down.
Loading Up With Day Hike Gear: every day hike item fits easily into this roomy pack (and I pack heavy) with room to spare and enough compartments to keep organized (other than lack of hip pockets) but without adding too much weight.
First Few Hikes: loaded up to 25 pounds and so comfortable, carried like an empty pack. Waist belt did seem to slack off a little though, hopefully just a break in thing.
Most Recent Hikes: loaded up to 45 lbs and tested overload compartment. Still rode very comfortably and I think another 15 lbs would not be an issue at all. Overload shelf carries weight well but I dont like that items (trekking poles) in side pockets can somewhat adjust into overload area, not by any means detrimental, just a little clumsy. Also waist belt still requiring periodic retensioning.
Overall: I tend to point out flaws but really this is going to be a great day-hunt pack this fall and I could easily see pulling off a couple of early season overnighters with it. I ordered hip pockets so that should help my overall function. Great job Mystery Ranch, keep it up.

Good quality, not fully field tested yet
I got this back for day hunts here in AZ for the ability to use the popup/loadout feature to pack out Coues Bucks and other AZ game. I like the quality and the fit, but still working the load set up for the stuff I always have in my back. It does squeak somethings when walking, but still adjusting straps to figure it out. More to follow, but so far so good.

Best Elk hunting day pack in the business!!
I bought this pack after owning a pop-up 18 that was just amazing for a day pack and getting that first load out after we downed an elk. I loved how concise the pop-up 18 was, but I just lacked a little room I needed to get everything I wanted. This pop-up 38 is just about perfect. I love the layout, and the pockets, and I added a couple molle water bottle holders and this thing is perfect! The main bag does not sit super tight to the frame when you don't have a meat bag, so be aware of this. I just took a couple extra straps I had from another pack and made a loop around everything so it would hold it back a little tighter. I love how this pack extends the stays and keeps the weight up on your hips and off your shoulders. Excellent pack, super well-made, and very functional.

Decent bag
I used this pack for 2020, a few weeks elk hunting and a season of white tail. Definitely got use out of it, liked it but could be better. If a few things were changed up it would be lights out. First, the waist/hip belt is too small. I ordered utility pouches to attach, they didn't fit with the molle. Was only able to use one of the straps and rigged the other one on. I attached a holster as well, unless you're flexible you won't be able to reach it cause it sits too far back. I use Nalgene bottles and the external pouch wasn't great cause of the straps, do they go over the water bottle or under?! Lastly, if it had a couple straps to attach your bow, it would be amazing. My buddies strapped their bows up while I was stuck carrying mine. Yeah I could of added some sort of strap, but I didn't. If those few things were changed, added or tweaked it would be a lights out bag that could be used for everything!
