More velcro
Just put ours up. The material is tarp material...no breathing or air flow. One of the bottom hooks on the foot of the pole is torn. No velcro staps in the middle of each side. The door side (zipper enterance) does not have 2 velcro straps that are NEEDED to attach to the canopy to hold the zipper taunt. You have to grab the top of the zipper to get it to where you can zip it down. We are currently using clamps on each side of the zipper to pull it taunt. These will not consistently hold it when pulling the zipper dow. Outside of that it fit together with the zipper closure on the corner of the legs. Not sure how this material or the velcro will hold up.
