Sea to Summit Ultra‑Sil Dry Bag 5L (Blue Atoll) — practical mid‑size waterproof storage that balances capacity, durability and ultralight performance.
The 5L Ultra‑Sil Dry Bag in Blue Atoll is a versatile organiser for day trips, overnighters and travel where space matters but weight still counts. Made from bluesign®‑approved 30D Ultra‑Sil fabric reinforced with CORDURA® yarns, it offers a reassuring durability for storing clothing, cook kits or electronics. The semi‑translucent fabric lets you quickly identify contents, saving precious time in camp or during transitions. A Hypalon non‑wicking roll‑top and taped seams ensure dependable protection against rain and splashes so your essentials stay dry.
Its oval base prevents rolling and nests cleanly inside backpacks and duffels; the slippery finish aids fast loading and unpacking. The PFC‑free DWR provides water beading performance with fewer environmental trade‑offs. Weighing only 32 g, the 5L Ultra‑Sil is light enough to be carried as a primary internal organiser or as a standalone dry bag for shorter trips — a reliable choice for hikers, cyclists and travel professionals.
What We Love
The 5L’s practicality is its standout feature: roomy enough for key items yet almost weightless. The translucent material shortens search time, Hypalon closure and taped seams deliver solid waterproofing, and the oval base improves stability. It’s a compact but highly functional piece of kit.
