Style: Regular
One of the best on the market. Works really well. If you have the right boots, get the clip style though(easier in the tree to get off)

  • Great knee ascender
Style: Regular
Expensive, but very well made a very effective. Made with top shelf components and is well thought out. Makes climbing much easier than hump’n (hip thrusting) your way up to the top floor of a tree!
