The Sea to Summit dry bag is a staple in my outdoor gear arsenal. They are versatile bags that can be used for storing clothing, electronics, food, and all other valuables that need protection from bad weather. The two that I use are the Sea to Summit eVent and 30D Ultra-Sil dry sack. I have traveled on bike with these bags for years across rough terrain and never once have been delicate with them. These work horses are durable, water proof, spacious and have the ability to compress to the size of a coconut depending on how you pack them.
The eVent is the burlier of the two and the most popular of dry sacks. It has a tougher waterproof ripstop fabric than my 30D Ultra-Sil dry sack. At 15 liters this bag can house my Hilleberg Akto tent and Therm-a-Rest Neo XLite sleeping pad that can be mounted to handlebars or placed into a Revelate Designs Sweet Roll handlebar bag. I also have extra room to fit other items if needed. However, I like to keep my cockpit weight down so the less weight the better.
The 30D Ultra-Sil dry sack is a lightweight bag designed to compress your gear without adding unnecessary weight. The bag uses a ripstop siliconized Codura fabric that is lightweight and durable that I use to store clothing and other small items. I put this bag in my Revelate Designs Viscacha saddle bag for bikepacking trips to keep my clothing dry and compressed.
I have had my Sea to Summit eVent well over 4 years now and my 30D Ultra-Sil for 3 years. They have served me very well and have never failed in keeping my gear dry. If you’re looking for something more durable, the eVent dry sack is the way to go as it is a stronger fabric. If lightweight and ultra compression is what you’re looking for I would recommend the 30D Ultra-Sil.
