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. Wherever and however hard core your work or play, the Second Front's got your back, and your front.

» HardPoint Guide

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.

Great Bag after 2 years of adventureReview by Nick
(this review is for the original version of the bag, before the hard point system) Im a traveler and so far ive taken this bag with me to 8 different national parks and through countless days of study, work, and play and its held up to it all wonderfully. I would absolutely recommend this bag to a friend (infact I have) but I do have a warning about the new (with the hard point system) version of the bag. One of the things I like the most about my version is that the hip belt has several mole attachment areas on it which are great for securing the Hazard 4 camera bags etc while im hiking. In this new version they have taken those mole attachment areas away so be warned of that.

Overall this bag is incredible and holds up very well to the test of time and travel. Not a fan of new belt design. (Posted on 3/7/2018)

It is the most perfect backpack wich i've ever had. (Posted on 4/11/2017)
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)

what's the difference between this and the sidewinder?
Hello. Thank you for contacting us. The main difference is that the Second Front is the backpack version of our Sidewinder. As such, it comes with a non-removable belt as opposed to the main single-strap on the SideWinder (for stabilizing purposes). An item included for the Second Front is the sternum strap instead of the Stabilizer strap used for the SideWinder. If your laptop is more than 15" and does not fit in the back pocket, you may use our Cartridge™ padded laptop sleeve insert that clips securely to the loops inside the floor of the bag.

Hope this helps!

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

Although this question was asked some time ago: Is the waist belt removable like all the pictures show?
The new version of the Second Front as pictured on our website, now has a removable waist belt.
