- Why Bulletproof Zone?
The Hazard 4 Second Front is a 20.1-liter daypack built around a single defining feature: it rotates from your back to your chest on the fly. Drawn from the same design DNA as the Sidewinder sling pack, the Second Front scales that concept into a full two-strap daypack — wide enough to carry a padded 15-inch laptop, organized enough to serve as a field office, and nimble enough to swing to your chest for on-the-go access without ever setting the bag down. The shell is constructed from Cordura military-grade Nylon 6,6 fabric with a double PU water-repellent coating. It weighs 3.2 lbs. (1.5 kg) and measures approximately 18" L x 11" W x 6.2" D. Available in Coyote and Black.
Who this is for
- Travelers and commuters who need quick access to documents, devices, or gear in crowded spaces without removing the pack
- Outdoor and range users who carry hydration, organize small tools or optics, and want MOLLE real estate for expansion without switching to a larger rig
- Professionals and students who move between a desk environment and fieldwork and need a single bag that handles a laptop, tablet, and organizer load in one carry
Rotation system and access
The core utility of the Second Front is the front-to-back rotation. Pull the bag to your chest and the main compartment faces you — ideal for vehicle interiors, ski lifts, crowded transit, or any situation where keeping the bag in your line of sight matters. The large grab handles on the bag frame this maneuver: you can rotate quickly without fumbling with buckles. In back position, the thermoformed back panel maintains pack shape and provides air ventilation against the spine. The ergonomically cut shoulder straps use 3D air-mesh on the underside for all-day comfort.
MOLLE coverage and organization
The Second Front runs MOLLE-compatible webbing across the front and sides, with additional modular webbing on the side panels for expansion pouches, phone carriers, and magazine storage. Double grommets support the HardPoint series of accessories. The front panel includes molle cutouts alongside a drop-down fast-access gear organizer that functions as a work surface and includes an iPad-sized tablet window. The main compartment interior is lined in fuzzy loop material for attaching dividers, patches, or compatible hook-backed holsters and accessories.
The hydration back-pocket accommodates bladders up to 100 oz. (3L) and includes a trap-door port for the hydration hose — no sharp hook-and-loop edges on the hose exit. The hydration pocket also includes a fuzzy loop panel for attaching an optional hook-backed modular pistol or magazine holster covertly inside the bag.
Laptop and tablet carry
The dedicated laptop compartment measures approximately 17.4" L x 10.5" W x 0.8" D with padded retention and fits most 15-inch laptops. If your laptop exceeds the compartment depth, the main compartment floor accepts the Hazard 4 Cartridge padded laptop sleeve insert, which clips securely to the internal loops. The main compartment itself measures 17.7" L x 10.5" W x 6" D — enough volume to serve as the primary carry space for a sleeve-protected laptop plus accessories.
Weapons accommodations
The main compartment fits folding-stock rifles and submachine guns with short barrels — H&K G36C and UMP are cited examples. Side flat-pockets accept paddle holsters and rifle magazines. The MOLLE front and sides accommodate holster and magazine pouches at hand's reach. The hydration pocket fuzzy loop panel supports covert attachment of an optional hook-backed pistol or magazine holster inside the bag body.
Construction and hardware
The shell is Cordura Nylon 6,6 fabric, double PU water-repellent coated. All zippers are YKK with silent paracord pullers that work with gloves and don't produce reflective flash. Compression straps run the exterior and double as retention for tubular items. The waist belt uses a large locking buckle for rapid drop and is included as a removable component. A sternum strap is also included. The bag includes a 3D Hazard 4 logo in subdued Black or Coyote finish depending on colorway.

Care and maintenance
Do not machine-wash or machine-dry. Empty all pockets and shake out debris. Soak in lukewarm water with mild detergent for 10–15 minutes and agitate vigorously. Use a clean cloth or sponge for general cleaning; use a soft brush such as a toothbrush for zipper teeth and corners. Rinse thoroughly. Dry metal parts completely as quickly as possible. Apply a zipper-specific lubricant to improve slide action. Turn the pack inside out and hang to dry in shade. Keep away from direct sunlight — UV exposure degrades and discolors the fabric.
Frequently asked questions
How does the front-to-back rotation actually work?
The shoulder straps and sternum strap are designed to allow the entire pack to swing from your back to your chest in a single motion without removing either strap. The large grab handles frame the maneuver. Once on your chest, the main compartment faces you for full access. Swing it back when you're done. No unbuckling required.
What laptop size fits in the dedicated sleeve?
The laptop compartment fits most 15-inch laptops. The interior measures approximately 17.4" L x 10.5" W x 0.8" D. If your machine exceeds the sleeve depth, the main compartment floor accepts the separately available Hazard 4 Cartridge padded laptop sleeve, which clips to internal loops.
Is the waist belt removable?
Yes. The waist belt is removable and ships included with the pack. It uses a large locking buckle designed for rapid drop. A sternum strap is also included.
Can this accommodate a hydration bladder?
Yes. The dedicated hydration back-pocket fits bladders up to 100 oz. (3L). A trap-door port routes the hydration hose out of the pack without sharp hook-and-loop edges against the hose.
What MOLLE accessories attach to this pack?
The front panel and side panels run MOLLE-compatible webbing. The front also has molle cutouts and double grommets for the HardPoint accessory series. Standard MOLLE pouches, phone carriers, holsters, and magazine pouches all attach. The internal fuzzy loop lining accepts hook-backed accessories including compatible Hazard 4 holsters.
Does the Second Front replace the Sidewinder sling pack?
It is not a direct replacement — it is the two-strap backpack version of the Sidewinder concept. The Sidewinder is a single-strap sling pack. The Second Front carries more volume (20.1 L) on two shoulder straps and still rotates to the chest. If you want the Sidewinder's front-access feature but need both-shoulder carry and more capacity, the Second Front is the direct upgrade path.

The Bulletproof Zone Promise
When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.
1. Authorized dealer of every brand we carry
Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.
We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.
2. Best price, guaranteed
If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.
Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.
3. Free fitment consultation
Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.
4. Trusted by thousands of customers
Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.
Price Match Guarantee — Terms
- You must have purchased the item from our website before requesting the price match.
- Discounted items and "free with purchase" items are not eligible.
- The item must be in stock on the competitor's website at the time of your request.
- The price match is valid for six months from the date of your purchase.
- The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
- The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
- Price match applies to the item price plus shipping. Sales tax is excluded.
To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
