The Sea to Summit dry bag is one of the staples in my outdoor gear arsenal. They are such versatile bags that can be used for storing clothing, electronics, food and all other valuables you have from bad weather. They also make great garbage storage bags for overnight camping when tied to a tree protecting you from bears. The two that I use are Sea to Summit eVent and 30D Ultra-Sil dry sack.

The eVent is the burlier of the two and most popular of dry sacks. It’s a tougher waterproof ripstop fabric than my 30D Ultra-Sil dry sack. At 15 liters this bag houses my Hilleberg Akto tent and Therm-a-Rest Neo XLite sleeping pad mounted to my handlebars. I also have extra room to fit other items if needed. However, I like to keep my cockpit’s weight down so the less 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’s super lightweight and durable. I use this bag to store all my clothing and other small items if needed. I put this bag in my Osprey backpack for camping trips or my Revelate Designs Viscacha saddle bag for bike touring.

I’ve had my Sea to Summit eVent well over 3 years now and my 30D Ultra-Sil for two. They have served me very well and have never failed in keeping my gear dry. If your looking for something more durable the eVent dry sack is the way to go. It’s a tougher fabric. If lightweight and ultra compression is what you’re looking for I’d go with the 30D Ultra-Sil.
