Ultra-light Dry Bags

The Ultra-light Dry Bag range, supplied by J3Seven, offers a simple, reliable way to keep your gear dry and organised whether you are on the water, in the field or travelling. Built from ultralight 40D ripstop nylon with a waterproof PU coating and taped seams, these roll-top bags help protect clothing, electronics and emergency equipment from rain, spray and wet packs.

Available in four practical sizes – 1 litre, 4 litres, 13 litres and 35 litres – and colour coded for quick identification, they are ideal for Defence, law enforcement, marine safety, remote workers and outdoor users who need to manage kit efficiently in all weather.

Why Teams Choose Ultra-light Dry Bags

Proven waterproof protection: The PU-coated ripstop fabric and taped seams help keep water out when the roll-top is correctly sealed, protecting clothing and equipment from rain and spray.

Ultralight 40D construction: Lightweight 40D ripstop nylon keeps overall weight low, making these bags suitable for personal load carriage as well as marine grab bags and vehicle kits.

Easy roll-top closure: The roll-top opening is simple to use and creates a reliable seal; once rolled, it closes securely with the buckle.

Durable buckle grab handle: The buckle not only locks the bag closed, it also provides a handy grab loop for pulling the bag out of packs or clipping it to other gear.

Colour-coded by size: Different colours for each capacity make it easy to identify volumes at a glance and standardise packing systems.

Multi-role protection: Ideal for marine survival equipment, field clothing, spare gloves and hats, documentation, comms kit and other items that must stay dry.

Frequently Asked Questions

How do I choose the right size?

Use 1 litre for small items like phones, keys and compact first aid; 4 litres for a set of spare clothes or core kit; 13 litres for larger clothing sets or equipment; and 35 litres when you need to keep a significant amount of gear dry, such as bulk clothing, group food or marine safety equipment.

How waterproof are these bags?

The bags use PU-coated 40D ripstop nylon with fully taped seams and a roll-top closure. When rolled at least three times and buckled correctly, they provide excellent protection from rain, spray and wet packs. They are not designed for long-term deep submersion.

Can these dry bags be used for marine survival kits?

Yes. They are well suited to marine survival and boating applications, where keeping emergency gear, clothing and rations dry is critical.

Are they suitable for regular fieldwork?

Yes. The ultralight construction and durable buckle make them suitable for repeated use in Defence, policing, remote work and outdoor environments.

Can I mix sizes in one system?

Absolutely. Many users standardise their packing by using smaller bags for valuables and electronics, medium bags for clothing and larger bags for bulk kit, all colour coded for fast recognition.
