Fabric Requirements: (this is an unlined bag)

80 – 98cm wide – 0.95M

98 – 150cm wide 0.70M

Leather Strap Version: 

Rivets or chicago screws 8 x 9mm

Metal sliders 4 x 1″  we recommend using these

Leather Strap 2 x 1″ x 89cm long (if you are buying our leather straps they come about 145cm long so you will need two of these). We find the split cowhide leather straps move the smoothest through the sliders.

When inserting the rivets we recommend using a very solid surface like a cement floor so there is no movement. You will just need a hammer to set the rivets, but you will need something to make a hole in your leather, we recommend a revolving hole punch. 

Webbing Version:

Metal sliders 2 x 1″. The sliders you need will slightly depend on the webbing you use, if you are using our plain webbing or Long Road webbing these loops work the best.

1.6m of webbing 3cm wide. We recommend our Long Road, or Plain Webbing.
