While this appears to be a good bag (looks like HD PVC material [like my drift raft]) for a top-side catch bag, I prefer to keep my catch in the hull to keep my kayak from being "top-heavy" upon landing.
For the price I'd buy my Canyon Redfish/Kayak bag ($100) all over again.
For about $12 more I'd think about one of these
