Sea to Summit Lightweight Dry Bag

A do-it-it all series of dry bags that can handle abuse and water while staying light enough to bring on any adventure.

Ease of Use/Features

The Sea To Summit Lightweight Dry Bag is just about as simple as a dry bag can get—a waterproof nylon bag with a roll top. That said, there are a number of features that Sea To Summit touts on their product listing for these bags.

1: Recycled 70D nylon fabric. Sea To Summit's proprietary dry bag fabric is...PFAS- and PFC-free! 

2: Light-reflecting white interior for better visibility of gear. I must admit, this is not something I ever considered before checking the Sea to Summit product page, but is absolutely a plus for these bags. Whenever I open the bag up, it is very easy to find gear that drifted to the bottom even in low-light conditions. 

3: Oval base prevents rolling away and packs better. I have never experienced  an issue with dry bags rolling away from me down a hill, but the shape of these bags absolutely helps them pack well inside other bags. I have two (the 13L and the 8L) and when I've brought them backpacking they slot in between sleeping pads and bags quite neatly and don't take up excess room.

4: D-ring attachment point at buckle for securing to boats, bikes, and kayaks. The D-ring is a small loop next to the buckle on the roll-top. I have never used this D-ring for anything. When it comes to attaching the bag to a raft or paddleboard, or hanging it from a hook/branch, I have always used the loop created by the roll-top when it is closed. The D-ring feels somewhat small and flimsy, and certainly less durable than the roll-top or the additional rubber hang point attached at the bottom of the bag. 

Construction & Durability

As I previously mentioned, the Lightweight Dry Bags are constructed out of recycled nylon fabric, and are generally very durable. I have had my bags thrown onto sharp rocks, catch on tree branches, and roll through dirt, with zero scratches, cuts, or even minor blemishes to the bag. While not as heavy duty as other bags Sea to Summit sells, for the average adventure, there is little that could damage the Lightweight Dry Bags. 

The Lightweight Dry Bags are, as their name implies, dry. While Sea to Summit explicitly states not to submerge these bags, I have submerged or soaked these bags entirely on multiple occasions, with the inside staying completely dry. The bags also absolutely classify as lightweight, with the 8L and 13L versions I own coming in at 2.4 and 2.9 ounces respectively (the largest size, 35 L, weighs only 4.1 ounces).  

Used in...

I have used these bags for the last year or so as my primary backpacking organizers, while backpacking, as well as extensively for paddlesports. I've taken both bags to Patagonia where they have had to withstand heavy rain and snow, and have taken them rafting on the Arkansas River. Most often, I use my bags to hold my food, layers, electronics, and anything else when I go paddleboarding or kayaking.
