The Hazard 4 Rocket '17 is a 31.6-liter ambidextrous urban sling pack built for professionals who operate in confined spaces and need to move fast. Constructed from Invista 1000D Cordura with dual-layer PU water-repellent coating, the Rocket '17 weighs 2.4 lbs and measures 19.75" x 13" x 7.5" overall. A thermoformed semi-hard front case, full MOLLE coverage, and YKK zippers throughout separate it from earlier Rocket variants. Available in Black and Coyote Tan.

Who this is for

• Military, law enforcement, and security personnel who need rapid pack access in vehicles, aircraft, or crowded environments where a full backpack creates too much profile.
• Shooters and range-goers who carry SBRs, pistols, or multiple magazines and want organized weapon accommodation without advertising their load.
• Outdoor and urban EDC users who cover long distances on foot or by vehicle and need a single-strap carry that keeps a long gun comfortable on the shoulder.

Design and construction

The shell is Invista 1000D Cordura with PU coating applied twice for superior water resistance. The front cap is thermoformed into a semi-hard case that protects contents and gives the bag its distinctive silhouette. The back panel is thermo-moulded with a logo and air-circulation array. All zippers are YKK with silent paracord pullers that work with gloves and avoid audible giveaways in the field.

The shoulder strap carries 3-D airmesh padding and a stabilizer strap that clips to either the right or left lower corner, automatically realigning the padded section in an ergonomic, body-hugging direction. The bag rotates to the chest for on-the-go access; every pocket faces the user in chest-carry mode whether worn left or right. A single-strap carry geometry also makes shouldering a long gun comfortable, unlike a two-strap backpack design.

Compartments and organization

The main compartment measures 19.75" x 7.8" x 6.1" and opens via a top-panel zipper accessible while the bag sits on the chest. Internal mesh zip and elastic pockets organize smaller items inside. The bag accepts a hydration bladder up to 2 liters (67 oz.) with bladder interference fit up to 2.5 liters of a 3-liter bladder, and routes the hose through a trap-door pass with a large bite-valve cover.

Two large side pockets each measure 9.25" x 5.1" x 3" and accommodate up to a 1-liter Nalgene bottle, with flat outer pockets on each side for paddle holsters or rifle magazines. An additional flat front pocket provides a third external access zone. One large pocket on the front face is optimized for chest-carry access and includes a built-in organizer. Top and bottom compression straps cinch the load and can also secure tubular items.

The front MOLLE cutout field measures approximately 5.5" x 5.5" and accepts hook-backed accessories directly through die-cut apertures in the fuzzy loop patch. Full MOLLE webbing wraps around the exterior for attaching holsters, magazine pouches, and additional accessories.

Weapons accommodation

The large external and side flat pockets fit multiple rifle magazines. A fuzzy panel inside the hydration pocket accepts optional hook-backed holsters. The main compartment accommodates firearms up to an H&K G36C or MP5 with collapsing stock, as well as most full-size semi-automatic pistols. The roto-locking side-release buckle on the main closure operates with thick gloves.

Frequently asked questions

What fits in the Rocket '17's side pockets?

Each of the two side pockets measures 9.25" x 5.1" x 3" — enough depth to hold up to a 1-liter Nalgene bottle with room for a flat outer pocket alongside it. They also accept paddle holsters and standard rifle magazines.

Is the Rocket '17 truly ambidextrous?

Yes. The stabilizer strap clips to either the right or left lower corner, and the padded section of the shoulder strap automatically realigns to the ergonomically correct angle for the chosen side. The bag can also be rotated to the chest, with all pocket faces oriented toward the user regardless of carry side.

What firearms fit inside?

The main compartment accommodates rifles up to an H&K G36C or MP5 with a collapsing stock, and most full-size semi-automatic pistols. Several reviewers have confirmed carry of 10.5" SBRs broken down, as well as the Sig MPx. Fit will vary by configuration; contact us if you have a specific weapon setup to check.

Does it work as a hydration pack?

Yes. The main compartment accepts a hydration bladder up to 67 oz. / 2 L, and can physically fit a 3-liter bladder used up to 2.5 L capacity. A trap-door hose pass with a large bite-valve cover routes the drinking tube cleanly to the shoulder strap side.

How do I clean the Rocket '17?

Do not machine-wash or tumble-dry. Empty all pockets and shake out debris. Soak in lukewarm water with mild detergent for 10–15 minutes and agitate gently. Clean stubborn spots with a soft cloth; use a soft brush on zipper teeth. Rinse thoroughly, dry metal parts promptly, lubricate zippers, then invert and hang dry in shade — direct UV exposure can degrade the fabric and coating.

How is the Rocket '17 different from the original Rocket?

Three changes distinguish the '17 revision: a thermoformed semi-hard front case and cap, MOLLE cutouts through the larger front loop-patch field, and the new roto-locking side-release buckle that operates with thick gloves. The '17 also adds two large side pockets that fit a 1-liter Nalgene bottle, a flat front pocket, and greater overall volume at 31.6 liters.
