Good pack

by -

I bought this pack to use as a hunting pack (mostly for coyote/predator hunting)… it holds pretty much everything I need and then
Some. I do wish the largest part of the pack had some hook and loop panels or molle on the interior for better organization, but overall I am pleased with it. I did wrap the zipper pulls in some gear aid camo tape to reduce the noise when walking into and out of stands. With a few small upgrades, I’d be willing to pay double the price. Other than that, it has plenty of room and seems to be well made.

Not bad for the money

The pack is a good size and design. It does not have high strength double or triple stitching found on actual duty gear, and the top carry handle is sewn slightly off center; but it's not bad for the asking price.

Nice Bag

I received the bag in a very timely manner after the purchase. It is much bigger than I expected. Lots of room for all the essentially needed gear.

Great pack!

I bought this on sale for $19.99 and it is worth way more than that! I’ve bought several other backpacks for around the same price and they were not that impressive. This one is awesome! The zippers and straps are good quality and there’s tons of storage space. Don’t hesitate to buy.

Far exceeded expectations

I ordered this backpack just for a spare throw around and because it was a really good price. It came and I was shocked at all it could carry, how well it was made and how good it actually looked. I used this for airline travel as my go to and it works great. Had an LL Bean pack for years and swore it was the best. This tops it.

Azz backpack that you'll be able to cram everything into, literally, EVERYTHING!

Great hunting pack

The 3 day backpack is slim enough to take on everyday or hunting trips and the main compartment can be unzipped and expanded as needed for more room.
