Materials & Construction
Waterproof 600D Recycled Polyester — Weather Protection
The Meridian Waterproof Tote Pack uses waterproof 600D recycled polyester fabric designed to provide dependable protection against rain, splashes and wet environments during everyday use.
This durable fabric construction helps shield equipment from moisture while maintaining enough structure for easier loading and carrying throughout daily travel and commuting.
ReShield Fabric Construction — Recycled PVB Protection
The Meridian uses Sea to Summit’s ReShield fabric construction, which incorporates recycled PVB film reclaimed from discarded vehicle windscreens. PVB (polyvinyl butyral) is the strong laminated layer normally used inside car windscreens to improve impact resistance and prevent glass shattering.
By repurposing this material into the pack’s laminate construction, Sea to Summit creates a fabric that combines durability, waterproof performance and abrasion resistance while helping reduce landfill waste from automotive recycling streams.
This reinforced laminated structure improves long-term durability while supporting a lower-impact manufacturing approach.
Fully Taped Double-Seam Construction — Waterproof Reliability
The Meridian uses fully taped double-seam construction to help prevent water ingress through stitched areas of the pack.
Combined with the waterproof fabric and roll-top closure, this construction improves overall weather protection during wet conditions and waterside use.
Non-PFAS Construction
The Meridian is built using non-PFAS materials, meaning it avoids the use of per- and polyfluoroalkyl substances commonly found in traditional water-resistant outdoor fabrics and coatings.
By removing PFAS from the construction, Sea to Summit reduces the long-term environmental impact associated with persistent chemical treatments while still maintaining dependable waterproof protection and durability.
Features & Technologies
Roll-Top Closure — Dry Bag Inspired Protection
The roll-top closure system uses proven dry bag principles to help seal out rain, splashes, sand and moisture during travel and everyday outdoor use.
Rolling and clipping the top creates a more secure weather-resistant seal compared with traditional zip openings, making the pack especially useful around beaches, boat trips, commuting in wet weather or unpredictable outdoor conditions.
When fully rolled and closed, the pack provides approximately 25 litres of usable capacity.
Convertible Carry System — Tote to Backpack
The Meridian can be carried by hand, worn over the shoulder or converted into a backpack depending on the journey and load.
Tote carry works well for everyday errands, shopping, and quick access situations, while backpack carry is more comfortable for longer walks, commuting, or carrying heavier loads over extended distances.
The padded backpack straps detach quickly for streamlined carry and easier packing when not required.
Stiffened Carry Handle — Improved Handling
A stiffened carry handle improves comfort and stability when lifting or carrying the tote by hand.
Hypalon Attachment Loops — Reinforced Stress Points
Reinforced Hypalon attachment points improve durability around key stress areas while also providing secure attachment locations for accessories or additional gear.
Internal Organisation Pocket — Essential Storage
An internal pocket helps organise smaller essentials separately from the main compartment for easier access during travel and everyday use.
How does it carry?
The Meridian Waterproof Tote Pack is designed to adapt easily across urban travel, commuting and outdoor environments.
Its convertible carry system allows quick switching between tote and backpack configurations based on comfort needs, while the waterproof roll-top construction keeps gear protected in changing weather.
