TETHRD PREDATOR PLATFORM PACK The Predator Pack can be worn as a stand alone pack (minimalist pack straps included), or used as an attachment for your separate, more fully featured pack. Use it as a stand alone (add a couple SYS Haulers on the outside) pack during the early season. When it gets colder, attach the Predator Pack to a separate pack and use it as a compression panel (Compression Kit required).
