BUILT TO KEEP YOUR PLATFORM HANDY DURING YOUR TREK WHILE YOU SEARCH FOR THAT PERFECT TREE.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.Tethrd likes to use theirs as a stand alone pack during the early season (add a couple molle pouches on the outside if you want). When it gets colder they 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.
