Second layer zips on and off to carry as many or few tubes as you want. Works great for 3 and 5 man play where different pack sizes may be required. Handmade means their built to last. Dual adjustable waist belts won't bounce, sag or shift even when fully loaded. Set the inner belt for comfort and the outer belt to lock down the paint. Expandable pod sleeves hold 100 to 140 round paint tubes. MSRP: $49.95 - $59.95.
The Smart Parts Zip Pack is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
