Sea to Summit Ultra‑Sil Dry Bag 8L — ultralight waterproof storage that keeps kit dry without weighing you down.
The Sea to Summit Ultra‑Sil Dry Bag 8L in Red is an ultralight waterproof dry sack engineered for backpackers, paddlers, kayakers and travellers who need proven moisture protection without adding unnecessary weight. Built from bluesign‑approved 30D Ultra‑Sil fabric reinforced with CORDURA® yarn and finished with a PFC‑free durable water repellent, it delivers an exceptional strength‑to‑weight ratio — offering abrasion resistance, low bulk and rapid packability in a sub‑pocket‑size package. A Hypalon non‑wicking roll‑top closure and factory‑taped seams form a dependable barrier against rain, spray and splashes, while the semi‑translucent fabric lets you visually identify contents quickly so you can locate clothing, food or electronics on the move.
The bag’s shaped oval base prevents rolling and stabilises the sack in pack compartments or boat cockpits, and the silky Ultra‑Sil surface makes stuffing and retrieval effortless in tight spaces; when not in use the dry bag compresses to almost nothing, freeing precious pack volume. With an 8 L capacity the Ultra‑Sil is sized to function as primary waterproof storage on multi‑day trips or as a mid‑size organiser for day hikes, commuting and expedition travel — keeping wet and dry kit separated, protecting sleeping layers and preserving food and electronics. For outdoor professionals and weekend adventurers alike, this Sea to Summit dry bag delivers technical materials, minimalist weight and straightforward waterproofing that solve the everyday problem of keeping gear dry and accessible.
What We Love
The Ultra‑Sil 8L balances featherlight carry with practical protection: its 30D Ultra‑Sil face fabric reinforced with CORDURA® yarn resists abrasion for real outdoor use, the Hypalon roll‑top and taped seams create a trustworthy waterproof barrier, and the semi‑translucent finish makes gear visible at a glance. The shaped base and slick surface mean less fumbling when packing boats or backpacks, and the PFC‑free DWR gives reliable water beading with reduced environmental impact — small details that make a big difference on extended trips.
