The Poseidon Deployment Bag is a waterproof rolling deployment bag built for military personnel, government agencies, and expedition travel. Combining waterproof protection, modular organization, and patented Shark Wheel mobility, it safeguards mission-critical equipment through airports, field operations, and harsh environments.
Constructed from 1000D Nylon with a rigid ABS frame system, its expandable design increases capacity from 110L to 150L to adapt to changing mission requirements. Three removable shelves, internal storage pockets, and dedicated document organization keep equipment protected, organized, and accessible throughout transit.
Patented Shark Wheel technology improves mobility across tarmac, pavement, gravel, and uneven terrain. Combined with wheelable, ruckable, and carry configurations, reinforced construction, and deployment-grade materials, the Poseidon delivers dependable performance wherever the mission takes you.
Available in two manufacturing standards to match procurement requirements. TAA-compliant units ($569) are in stock and available for direct online purchase. Berry-compliant units ($679), fully sourced and manufactured in the USA to Berry Amendment standards, are reserved exclusively for government and military procurement channels and are not sold through this website - contact our team to place a procurement order.

I have brought this bag to the most austere environments on multiple deployments and TDY where I’m living in the dirt, on boats, and everything in between. The bag just takes it. The durability of Thin Air Gear is unparalleled.

This bag has carried me through cross-continent trips for years without wearing out. I travel often, living overseas as a US citizen and it has yet to fail me across terrains, from Indonesia boats and rough roads, to European cobblestones. Can't reccomend it enough!
Gear For The Long Haul
Every Thin Air Gear product starts with the same standard: build it right, prove it in the field, and never compromise what carries the mission forward. All bags are backed by a Limited Lifetime Warranty.
The Poseidon Deployment Bag is built from rugged 1000D nylon with waterproof zippers to protect mission-critical gear from rain, snow, mud, and harsh environments. It is designed for professionals who need reliable protection during deployment and travel.
The Poseidon is ideal for military personnel, first responders, overland travelers, and professionals who require a waterproof tactical rolling duffel for transporting heavy gear in demanding conditions.
Each Thin Air Gear deployment bag is designed to support different mission requirements and travel styles. The Olympus™ Deployment Bag is built for large-capacity loadouts and extended deployments where maximum organization and durability are essential. The Poseidon Deployment Bag offers the same professional-grade performance with waterproof construction for wet environments and demanding weather conditions. For shorter trips and carry-on convenience, the Pike Deployment Bag provides a compact, TSA-friendly solution without compromising durability. If reducing weight is your priority, the Olympus Lite™ Deployment Bag delivers many of the organizational benefits of the Olympus™ in a lighter, more travel-friendly design. The best choice ultimately depends on the amount of gear you're carrying, the environments you'll be operating in, and how you travel.

Amazing bag! Received the bag for my 2015 deployment. 7 years later, I still use it every time I deploy or travel.

Usually I’d go through a travel bag every year, but your bag has held up through the last 5 years of heavy use. Thank you guys for making a product that can keep up with me.

I love the bag. It survived two deployments, which can be very rough. This will be my third time deploying with it.
