The CMBT Expandable Cooler is a lightweight, rugged soft cooler designed for full workdays, road trips, travel, and weekends out. Its structured insulated main compartment expands to approximately 12 inches tall, providing room for up to 12 standard cans with ice—or a complete meal with drinks and snacks.

When empty, the full body compresses to approximately 5 inches tall for convenient storage inside luggage, beneath a vehicle seat, or anywhere space is limited.

A separate lid compartment expands to approximately 4 inches deep, keeping dry snacks, utensils, and smaller essentials away from the main cooler. A dimensional front pocket, quick-access zipper, patch panel, and rear MOLLE webbing provide organized storage across the exterior.

The water-resistant 500D Oxford exterior is finished with rubber-coated zipper pulls and a textured rubberized base that protects against repeated contact with rough surfaces. Carry it using the reinforced paracord grab handle or attach the removable padded CMBT jacquard shoulder strap for hands-free use.

  • Versatile Carry System — Reinforced paracord grab handle and removable 1.5" CMBT jacquard shoulder strap with an adjustable padded section for comfortable hand or shoulder carry.

The lid expands to create an additional 4-inch-deep compartment for dry snacks, utensils, napkins, and smaller essentials. It keeps these items separated from the ice and cold contents stored below.
The insulated main compartment holds 12 standard 12-ounce cans with ice + room for lunch items. It can also fit a complete lunch with drinks, snacks, and utensils.
Cold retention depends on the outside temperature, amount of ice, starting temperature of the contents, and how frequently the cooler is opened. For the best performance, load it with already-cold items, use plenty of ice or frozen packs, and keep the lid fully closed.
Yes. The insulated main compartment can be packed with loose ice or reusable frozen packs. Ice packs are the better option when you want easier cleanup and prefer to keep food dry.
The 550 paracord-wrapped grab handles improve grip, comfort, and durability. They provide a secure hold, withstand years of daily use, and reinforce the tactical heritage behind the SACK™ Backpack's design.
Wipe the insulated interior with mild soap, warm water, and a soft cloth. Spot clean the exterior, empty any remaining ice or liquid, and leave all compartments open until completely dry. Do not machine wash or tumble dry.

    Fanny Pack Dump Pouch V2.5

    5/5 for me. I bought 8 of these in multiple patterns to give as groomsman gifts at my wedding and couldn't be more satisfied. Transparency on shipping times and communication was excellent. Product feels durable for typical wear and came in clutch on the honeymoon. They were so classy of a product that the fanny packs made it into a couple of the wedding photos.

    Thanks Rhett! 🔥 That's absolutely incredible — 8 Fanny Pack Dump Pouch V2.5s for your groomsmen is next level, and we're stoked they were such a hit! Love that they were classy enough to make it into the wedding photos and came in clutch on the honeymoon too. Sounds like your whole crew is now part of the Combat Iron family, which is awesome. Congratulations on the wedding and thanks for choosing our gear to celebrate with your brothers! 💪

    Best CCW Bag I have found!

    I have gone from a simple sling to a Hazard 4 Bandoleer. The Nomad by far is the best bag I own. It fits everything I need. You can tighten or loosen the straps based on load. The CCW slot allows me to take my holster and place it in the bag, allowing me to carry either way without a bunch of headache. Fits a Taurus G3XL perfectly. The bag sits well and it's just big enough to fit things for the kiddos and just small enough to not make it stand out like my Bandoleer. My only con to the bag is the back gripping to stick to clothing doesn't do much on loose clothing. If it is snug with like a hoodie or vest it sticks decent. Using more rubberized material might make it hold better. Still it's so good that my wife also wants to pick one up for when she gets her CCW.
