2-Day Assault 27L Daypack

Mystery Ranch's roots in tactical equipment shine through in the 2-Day Assault Pack, with the military-grade materials built for more urban missions. You'll likely first notice the 3-zip front, which makes access to the pack's contents fast. The triple zipper also allows you to store larger items more easily, and provides room for the two internal drop-in pockets for smaller items to stay organized. For further organization, Mystery Ranch adds a padded laptop sleeve and four zippered pockets to keep you from the duffle shuffle as you try to find your headphones.


  • Carry everything you need for any urban mission
  • Rugged 500D nylon is durable for years of use
  • 3-ZIP opening makes for fast access and easy packing
  • Multiple interal pockets organize items

The Tri Zip

I purchased this as soon as it arrived I went straight to field I utilized this bag as an AG bag carrying 50lbs of ammo and tripod attach for a gun team it worked very well the tri zip allowed me to lay the bag down and open it up like a display case to pull rounds out.

Perfect for EDC

I use it as my work bag, get my daily needs in and out of work. Big pockets inside to keep your junk separated. I'm 6'3" and I got the large, it's perfectly sized for me.

Superb Quality and Craftsmanship

I purchased this pack about a month ago, and it is impressive in quality materials and workmanship, couldn't be happier with my choice. Carries heavier weight better than other packs I own and I appreciate the compression system which truly secures the load and eliminates shifting.

Gets the job done!

I've put it through the wringer
Size Bought:
5' 7"

This backpack is in low stock or no stock as of 5/7/2024 for a reason. It's not too big for everyday carry (laptop + engineer stuff), if needed, the molle system allows for more carrying capacity and versatility. as a weekend backpack this pack will hold 2-3 days of gear. excellent hiking pack (if you do a 2-4 hour hike its too big, but for longer multi-day hikes this is the one). I ride a motorcycle to work so this pack is a great option for the task (it can hold the helmet also). I also fly once a month and having this as my carry on plus a waist bag makes the trip very easy; sometimes it's the only bag I take with me. If you can get this pack at a discount it's worth it.

Best pack I have ever used

I have had several packs over the past 20 years and this one is the best of them all. It is very easy to get in and out of making packing and unloading a breeze. I love all the organization and my personal favorite is all the points you can adjust to make it fit perfect to your particular body size.

The perfect overnight bag

I use this bag both as a quick grab and go over night travel bag, and as my day pack as the “family mule” for a family of four. The pockets and access are perfect (not too few, nor too many), two big pouches for water bottles, and the most comfortable shoulder straps I’ve found. I’ve been through an easy 5-10 packs over the year before finding this one; it’s the best I’ve found to date.

Great everyday/short travel bag

After a month of testing and daily use, I feel comfortable with the bag and its features. At first, it seemed like a lot but I have grown accustomed to its many interior pockets faster than I expected. I love the molle design, laptop zipper, lid pockets, and interior zippered pockets. However, the only downside I have is the quick-attach zoid bag does not line up with the interior loops.
