Finally, a durable whip suitable for every condition! Our new poly whips are made from high-quality polyethylene, meaning they're more durable than nylon and require no breaking in period. Unlike nylon, polyethylene does not deteriorate when exposed to UV rays. And yes, you can crack it even when it's wet outside! So take this whip to the ranch, or go play in the rain. If it gets dirty, just wash it with water. It's really that simple!
