If the REI ZipAll is not readily available, you can try a DIY approach. Just takes a little tailoring skills.
Start with one of those Scottevest RFID Travel Vest (26 pockets with RFID blocking). Sew on upper sleeves plus lower sleeves. You will then have an option of vest only, short sleeve or long sleeve jacket.
For those willing to forego RFID protection, start with a SCOTTeVEST Jacket for Men (25 pockets) with removable sleeve. You can add a short sleeve option by adding above the elbow zippers.
Connect vest/jacket hem with zippers to Pick-Pocket Proof Convertible Travel Pants (11 Total multi-secure pockets: 5 triple secure & 6 double secure). Those wishing a knicker pant option can add calf zippers.
The advantage of zipping together a Scottevest and Pick-Pocket Proof Convertible is the availability of tourist camouflage colors of olive greens and khaki.
