Awesome new backpack
I had the same backpack for over 20 years and I finally replaced it with a Wolfpak. I love all the pockets and the layout. I wish it had a clip in the front pocket. Love it.

I had gotten a cheap $50 tactical molle bag from tiktok 6 mo ago and its rotn to shreds. THIS bag tho 👀 if you need a tough bag for daily carry, that can handle being filled to the brim, this is the bag for you. Its tough, zippers move like butter. Got a cool couple welcome gifts. Will be getting several more now that i know it is 100% worth the price. If you need a trusty bag, just get it - you wont regret it.
