O'Brien Tear Aid Patch Kit - Quick Repair for Inflatable Boats, Kayaks, Tents & Outdoor Gear - Waterproof & Durable for Emergency Fixes on Adventures

I didn't expect much as most patch kits for towables are terrible. That being said, this kit actually works. It chemically bonds to the vinyl so the risk of coming off is eliminated. Be careful when applying it as once it touches the vinyl, it isn't going to come off without ruining the patch. Another great feature is that it can be applied on the go and the fix tube used within 15 minutes.
