Slightly oversized, the mat also provides a clean, dry workspace for brew making, rig tying, and any other tasks where keeping pouches and accessories off the ground is essential
Keep your belongings bone dry with the Ultralight RS335 Rain Cover. Designed to pack down small until needed, it deploys quickly and fits neatly over the rucksack while being worn. Beyond the rucksack, it also doubles as a versatile rain cover for accessories that need to be left exposed to the elements.
The Side Pockets are perfectly sized for essentials you don’t want loose in the main compartment. Ideal for compact binoculars, electronics, emergency waterproofs, and other items you need quick, secure access to.
The Front Pocket Attachment is designed for fast, efficient access. When fully opened, it provides instant reach to rig tools and terminal tackle essentials — ideal when getting rods out or moving swims. The front flap folds down to create a compact work surface or rig tray, while the upright section features dedicated terminal tackle slots to keep everything organised and close to hand.
Don’t let the size fool you. The RS335 Ruck Sack offers an impressive 33.5L of total storage, spread across its spacious main compartment and four external pockets. Perfect for a finely tuned kit list — and easily expandable for longer sessions.

Introducing the first of a new generation of Cotswold Aquarius luggage — where British craftsmanship meets modern modular design.
Big Capability in a Compact Frame
Don’t let the size fool you. The base backpack offers an impressive 33.5L of total storage, spread across its spacious main compartment and four external pockets. Perfect for a finely tuned kit list — and easily expandable for longer sessions.
Expand Your Capacity
Thanks to the Molle Attachment System, this backpack can quickly transform into a multi-day backpack using our bespoke range of ‘System Attachments’ (sold separately).
We’ve built the bag around the official MOLLE (Modular Lightweight Load-carrying Equipment) webbing standard — meaning any MOLLE-compatible gear will attach securely and neatly to the exterior. Between the side and front pockets, you’ll also find custom fittings for our exclusive Brew Tubes — padded, insulated, and easy to access. Perfect for brew kits, stoves, hooks baits, spare spools, bottles, or flasks — anything you need at arm’s reach.
Engineered for Comfort
After extensive testing and customer feedback, we’ve redefined comfort for this size of pack.
Increased padding for long-wear comfort
Refined strap placement for balanced weight distribution
Exclusive tensioning buckle system for instant on-the-go adjustment
Proudly Made in the UK
Every backpack is designed, developed, cut, and assembled in our UK workshop. Built to last, backed by our “Luggage for Life” guarantee, and finished with the signature Cotswold Aquarius attention to detail.
