Second Front™

rotatable backpack

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.

Great Products but it has some ConsReview by James M.
Very strong, water resistant and well made. the only real con I have is the air flow system on the rear of the pack does nothing at all, as soon as I put the pack on I start to get very warm along the straps and rear of the bag. I would love to see a Hazard 4 bag with a frame. (Posted on 10/10/2013)

Is the waist belt removable?
No. The belt is sewn permanently on the pack.

Is it water resistant? What's its waterproof/resitant rating in terms of PSI? Does there exist a sort of poncho / shell to envelope it into if rain?
Good Morning

All of our pack related products is outfitted with Cordura®, and you can look up the PSI rating for military grade Cordura® material on their website. Hazard 4 does not make a poncho/ shell to cover from rain, if and any case our customer needs that type of product, we recommend any brand covers as long as the size its correct it will work to keep the rain out.

Thank you for contacting Hazard 4
