Brand new, never used! Description from website: UltimAider OSP pack is a pack that was designed with the one stick climbers in mind. Although it was designed to house everything you need other then the saddle. It’s extremely versatile and can be used in many different applications. Similar to our aider this pack is a completely modular system and can be changed to fit your specific needs. Not only can you remove the side pouches but it gives you multiple ways to carry to your favorite hunting locations. With the included belt/strap you can wear it like a fanny pack or sling it over your shoulder by simply moving the strap from the rear loops to the top loops. Both of these options are nice to remove the weight that causes saddle sag off the saddle. However if you prefer the pack to attach directly to the saddle each pouch has that ability as well.
