The Workhorse Platform 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.
We like to use ours as a stand alone pack during the early season (add a couple molle pouches on the outside if you want). When it gets colder, we like to attach the Predator Pack to a separate pack and use it as a compression panel (additional straps required).
No matter how you use the Pack...it's a great piece of gear to make you a more efficient hunter.
