I used this hunting this year, I put it on my day pack and mostly used it to secure my coat and other layers when it got too warm going up mountains! The net is fantastic, the attachment system is quick, easy, and quickly transfers between packs. Only issue at all is the little carabiners that come with it are really cheap, it’d be five stars otherwise. Several already broke their springs. BUT they still work, and I will replace with better clips and get years of use out of this.
It is just small enough for my day pack, but would easily fit a full size backpack too.
