The XTC pack is the biggest of the four packs and just like a drug you will be hooked the first time you use it. This pack has every thing you could want in a stock class pack. With the ability to carry up to 38 tubes, 12 twelve gram cartridges, a fully padded back piece, and a padded cover that can be customized to fit your style. What else could you want? How about the ability to use it as a cap less pack or as a standard tube carrier with the lids on? Either way you choose you can't go wrong. And this ain't no mass produced pack either, not that the masses would ever play stock class. Every pack is hand made with double and triple stitching everywhere.
The Paintball Mafia XTC Pack is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
