HTTMT- Upgraded Tree/Pole Climber Climbing Spike Kit, Safety Adjustable Belt Lanyard Rope Rescue Belt With 2 Sturdy Gears,Life Adventure,Picking Fruit,Hunting Observation [P/N: ET-OUTDOOR002-A-RAW]

It's made of metal, maybe 1//8 of an inch thick. It came with 2 straps with buckle and 2 long straps with no buckle. There are no instructions so I just had to go by the product picture. Apparently i''m supposed to wrap the long strap around my leg and the spike then tie a know? I just made shorter ones and added a buckle. I haven't used it yet but these have the same exact design as the more expensive ones. I know people are freaking out about the zip ties but the newer ones are thicker. There are already holes there so you can replace the zip ties with whatever you want. Personally all the zip ties are there only to keep your legs on the spikes. It's not needed to hold your weight so I think it's sufficient.

Kool.

Overall, it's a well built item. Unfortunately, the various straps continued to loosen themselves as I tried to use them, so I had to return the item. Can't climb a tree with gear that falls off...

Very good brand
