When it comes to protecting gear from the elements while backpacking or camping, a reliable dry sack is essential. The Sea to Summit Ultralight Dry Sack is one such product that has garnered significant attention in the outdoor community for its exceptional waterproof performance and minimalist design.

Design and Construction

The Sea to Summit Ultralight Dry Sack boasts an incredibly lightweight build, tipping the scales at just 2.8 oz (79g). Despite its slender profile, this dry sack is built with a robust TPU-coated nylon fabric that provides excellent water resistance. The seams are reinforced with a durable PU coating for added protection against moisture.

The bag’s design features a simple and intuitive layout, consisting of a single compartment with a roll-top closure system. This allows users to easily access their gear while maintaining the dry sack’s waterproof integrity. A small zippered pocket on the front provides additional storage for smaller items like keys or snacks.

Waterproof Performance

One of the primary concerns when it comes to dry sacks is their ability to keep gear completely dry in wet conditions. The Sea to Summit Ultralight Dry Sack has been put through rigorous testing, and the results are impressive. With a waterproof rating of IP67 (immersion up to 1 meter for 30 minutes), this dry sack can withstand exposure to rain, snow, or even accidental submersion without compromising its contents.

Size Options and Capacity

The Sea to Summit Ultralight Dry Sack is available in three sizes:

• Small: 20L capacity
• Medium: 35L capacity
• Large: 55L capacity

Each size option features a similar design and construction, but with varying dimensions to accommodate different types of gear or personal preferences.

Durability and Maintenance

While the Sea to Summit Ultralight Dry Sack is designed to be rugged and durable, it’s essential to note that excessive wear and tear can compromise its waterproof performance. To maintain the dry sack’s integrity:

• Avoid using abrasive chemicals or cleaning products
• Regularly inspect the seams for signs of damage or wear
• Store the dry sack in a dry environment when not in use

Comparison to Competitors

The Sea to Summit Ultralight Dry Sack compares favorably to other high-end dry sacks on the market. For example:

• The REI Co-op Dry Sack is slightly larger and heavier (3.2 oz / 90g) but offers similar waterproof performance.
• The Mountain Hardwear Ghost Shadow Dry Sack is more expensive but features a unique, streamlined design with an even higher waterproof rating (IP69).
