Before we dive into the review of the Sentry Tumalo Extreme, I want you to think of everything you could hope for in a daypack.





If you can give me those four, I’m a happy camper. As soon as I unboxed the Sentry Tumalo Extreme, I was a happy camper. After having put this bag through it’s paces, I’m even happier.

First Impressions

It arrived box intact and well protected. The moment you lay hands on this daypack, something feels different. I’ll jump right into the construction of the pack. The body of the bag is made of 420 Denier Rip-stop fabric. That is a pretty common material amongst higher end backpack designed to cater to the tactical market. The difference, the one I described as being noticeable at first touch, is due to the entirety of the shell of this pack being laminated.


This laminate gives the bag a durable outer body that is snag proof but most importantly, waterproof. To compliment the waterproof body, Sentry uses Seam Seal Technology waterproof tape at the seams and YKK® AQUAGUARD® Zippers to ensure that your gear stays dry. In layman’s terms, this back is weatherproofed with the best materials it could ensure the protection of your gear.

How’s It Hang?

The Tumalo Extreme shoulder straps are adjustable in length and comfortable to wear. The bag has a chest strap that clips in front and removable waist straps that do the same. These ensure that the bag does not shift or move when secured to your back. The removable waist strap gives the Tumalo Extreme the versatility to go from the field, hunting or a day of shooting, to use for the professional World or the gym.


On the topic of versatility, Sentry has a new technology that they have unleashed on quite a few of their products recently. They call it 1080™ and long story short, it allows you attach anything using the MOLLE attachment system to your product at any angle. This effectively gives you the option to angle mount a MOLLE pouch and access it as you would a sling pack.


I would qualify this pack as a medium sized daypack at 27 liters. There are two pouches in the main pocket, one for a laptop and the other for a hydration bladder. There is an access slot for the hydration straw. The pack has two more pockets, one smaller and one medium sized. The medium sized pocket has individual pouches to separate items within it.

The Best Part…

The best part about this daypack is one rarely found in a medium sized pack, a frame. Not just any frame, one that has a suspension and a comfortable lumber pad. The suspension and lightweight frame means that the bag holds its shape and integrity when it’s loaded down. This also means that up and down hills, traversing boulders and jumping across creeks, this pack’s comfort and movement is not dictated by the contents of the backpack.

Wrapping Up

The Tumalo Extreme retails at $289.99. This is more expensive than even some of its higher end competitors. This pack features high end features that make it well rounded and justifies its price point. Trying to find a tactical style backpack that is weatherproof, features a legitimate frame and suspension in the neighborhood of 30 liters can leave the searcher wanting. This pack fits the bill of a versatile pack with volume, versatility, durability and comfort.
