I have the Field Bully Dog Blind from Rig Em Right and I love it. It is fully collapsible with a long strap that I put on my decoy bag or around my shoulders. It is extremely sturdy, comes with stakes for the corners, and a mat that can be removed to be cleaned. Also, you can leave both ends open for a dual-entry set up. My black lab male is around 80lbs and has no problem with it.
