Made of that gorgeous Swiss leather, thick enough to boil into a delicious stew, if starving… Heavy! Each pannier measures 16” x 12” x 2” wide, with big buckle down flaps. The two are connected with an adjustable leather strap, (which you could easily remove), and a couple of short chains with ‘biners for steadying the load. Great for many uses. We use ours as tool bags in our p/u truck, so the greasy tools don’t rattle around. We don’t have a bunch, so you’d better hurry.
