    Hazard 4 Second Front 18.3 Liter Rotatable Backpack Black

    Hazard 4 Second Front Rotatable Backpack Black, is the backpack version of our versatile Sidewinder™ sling-pack, this unique pro-quality day-pack has generous size to accommodate laptops in its padded retainer, yet is nimble enough to be rotated from back to chest. Common to all our slings, such as the Evac™ series, this maneuver gives on-the-go access to frequently used gear while carrying heavier loads on the back the rest of the time. It's also more secure in crowds etc., since you can keep it in sight and allows users to sit back in tight quarters such as ski lifts, or in vehicle interiors, etc. The generously padded and ventilated shoulder straps are also ergonomically cut for hours of comfortable wear per day, and it is covered in modular (MOLLE compatible) webbing to attach pouches for phones, etc. at hand's reach. Generous side modular webbing provides lots of expansion options and the thermoformed best-in-class moulded back panel provides variable rigidity, air ventilation, and a durable surface. A drop-down fast access gear organizer can also hold an iPad® sized tablet like a shelf and the main compartment is lined in velcro like fuzz for attaching dividers, patches or Hazard 4® holsters. A removable delta-retainer is included for keeping bottles and similar objects inside the side pockets of the Second Front™. Wherever and however hard core your work or play, the Second Front's got your back, and your front.

    PLEASE NOTE: The Second Front™ has been updated to include double grommets for our HardPoint™ series of accessories and molle cutouts on the front. There is also an updated waist belt design. The Delta™ strap is no longer included.
