The Viper Tactical One Day Modular Pack can be used either as a day pack or attached to a plate carrier using a MOLLE panel on the back of the pack. Additional MOLLE panels on the front and sides of the bag allow for customization, expanding the bag’s versatility. The compression straps can be used to compact the bag depending on your preferred loadout. The length of the webbing shoulder straps with quick-release buckles can be adjusted for a perfect fit. Inside the main compartment, you will find a water bladder pouch and the bladder hose can be threaded through one of the three comms/bladder outlets positioned on top and sides of the pack. The Viper Tactical One Day Modular Pack is perfect for most tactical operators, but it will also suit hikers and outdoor pursuits enthusiasts looking for a pack with extra features.
