Sea to Summit Ultra‑Sil Dry Bag 3L — ultralight waterproof protection that keeps small essentials dry without adding weight to your pack.
The Sea to Summit Ultra‑Sil Dry Bag 3L in Red is an ultralight, purpose-built organiser that protects your small kit from rain, river spray and damp storage. Constructed from bluesign‑approved 30D Ultra‑Sil fabric reinforced with embedded CORDURA® yarns, it offers a surprising level of abrasion resistance for its featherweight design. The semi‑translucent shell lets you identify contents at a glance so you spend less time unpacking and more time moving. A Hypalon non‑wicking roll‑top and fully taped seams provide a reliable moisture barrier, giving confidence when stowed in a wet pack or on a damp boat.
At only 30 g the 3L Ultra‑Sil functions as either a compact primary dry sack for minimalist outings or a lightweight internal organiser for longer trips where kit separation matters. The shaped oval base prevents rolling and helps the bag sit securely in pockets and duffels, while the low‑friction finish makes stuffing and retrieval fast and snag‑free. PFC‑free DWR beads water away from the surface, striking a practical balance between performance and reduced environmental impact. Ideal for hikers, cycle tourers and travellers who value visibility, packability and dependable waterproofing in a near‑weightless package.
