These worked great inconjunction with the field repair buckles for extending my existing straps on the F1 mainframe.

Great pack. Great workmanship. Love it.

This kit will put everything together for your system

Haven't used in the field yet, but grappled Switchblade to my mainframe and it works just fine.

It’s great

Only used them once, very secure and do what they are supposed to

Awesome accessory to add to our pack for shed hunting. Helps to allow us to add more hauling gear also.

Haven't had them long but quality is good and works well. Time will tell on durability

Worked perfect on my Kuiu pack

All of the products I’ve purchased so far are excellent! The F1 frame is comfortable and holds my climbing sticks perfectly. Customer service is top notch! Waiting for the batwing bags...
