Sea to Summit Ultra-Sil Day Pack
The Sea to Summit Ultra-Sil Day Pack is an award-winning minimalist backpack designed for ultralight performance without sacrificing strength. Crafted from 30D siliconized CORDURA® fabric and reinforced with bar-tacks at critical stress points, it can carry loads many times its own weight while packing down to the size of a tennis ball.
With a 20L capacity, it’s perfect as a summit pack, a lightweight travel tote, a grocery bag on foot, or an extra pack for cycling. When packed, it easily fits into your jacket pocket, purse, or attaches to your key ring using the integrated carabiner. While the shoulder straps are non-padded, the pack comfortably supports up to 15 lbs / 7 kg.
Whether you need a backup pack on trail, a compact travel solution, or an everyday carry option, the Ultra-Sil Day Pack is versatile, durable, and always ready to go.
