I like it. I've used one the past 2 seasons now. I have everything in it that I had in my tatr 2 vest. It's easy to carry and not nearly as hot as a vest
I use one now. Much lighter than a vest and can access things a lot easier. Some of my larger pot calls can be a pain to get in and out of the pockets and I've had some trouble with the bag falling over and loose items spilling if I'm hunting uneven terrain. However, I sit in a alpz outdoors turkey chair so I've made a habit of getting comfortable and sitting the bag open in my lap for access.
If I get lazy or is super warm a ThermaCell hanging off a belt loop, mouth call in shirt pocket and a 30 year old Lynch Jet slate in a side pant pocket.
Gloves, headnet, and a bottle of water in other side pocket. Grab a shotgun and go.
I got one that Tommy gave me at church. Before they hit store shelves. I use it as my run An gun set up. It's light nimble easy access very mobile An set up nicely to carry the essentials.
