Materials:
For the main side panels: I used 3-4 oz waxed veg tan, medium temper. 3-4 or 4-5 oz might work well. Probably not too stiff, as it has to bend at the drawstring.
For narrow gussets between the panels and pocket gussets - soft 1-2 oz leather like sheepskin (it is what I used), calfskin, deerskin, maybe goat, or upholstery.
For the bottom - 6 oz (the thicker your side panels are, the thicker the bottom should be, so it holds the shape against the thick seams)
For the straps and strap holders - 5 oz would do.
You will need a drawstring, I used a round leather lace.
Soft and thin leather (same as for gussets) strap approx. 24” long and 5/8 wide (edge tape)

Hardware:

2 x 3/4” buckles for pockets
3 x 1“ buckles for main closure strap and the strap adjustments
4 x swivel hooks (I used 1 1/4 on top and 1” on the bottom, if you decide to make straps your own way, that can change)
5 x 1“ D-rings
12 x #0 grommets (this can vary, just don’t use anything too big)
Rivets

Tools:

Scissors, knife (paper knife or rotary cutter would also work).
Stitching irons: my pattern is made for 5mm stitching irons (5 stitches per inch). If you
are willing to use any other size please make sure that the hole count is the same where
it has to be the same.
Needles - according to your thread size, a pair of harness needles.
Mallet, rivet setter, hole punch, 3/4” bag punch (oblong), grommet setter.
