Kakadu Australia CC Traveller Vest

What's the difference between the DELTA & TRAVELER? The Traveler is built using Kakadu's traditional 12oz oilskin for bad weather protection, the rest is the same, 18 pockets. 9 front patch pockets, 2 front zipper storage pockets, 2 side entry welt pockets, 2 internal security pockets, last of all is the 2 CCIS pockets. Brass zip closure, cowhide trim, full cotton lining covers the Kakadu concealed carry internal system (CCIS). Anti-imprint pads are not required as the 13 external front pockets distort any imprinting.
