Sea to Summit Lightweight Dry Sack, 20LSea to Summit Lightweight Dry Sack, 20L
This sack is for kayak campers who count every gram and want reliable protection from spray and rain. It suits paddlers who pack light and organize gear into several small sacks, and it works well inside a hatch where space is tight.
Key specs: 20L capacity. Weight 91 g. Recycled 70D nylon with a water repellent finish. Hydrostatic head 10,000 mm. Roll-top closure with a Hypalon buckle and a field repair buckle. Dimensions 47.8 x 27.1 x 23.4 cm.

- Lightest bag in this guide at 91 g, so it adds almost no weight to a loaded kayak.
- High hydrostatic head rating for strong protection against spray and rain.
- Soft fabric packs small when empty and fits easily in a hatch.

Some owners note the thin fabric needs care around sharp hatch rims, and a few say the 20L size is best for clothing and soft gear rather than hard items.

What size dry bag do kayak campers need?
Most kayak campers use several bags rather than one large bag. A 20L bag holds a change of clothes, a sleeping bag liner, or a day of food. A 10L or 13L bag suits a camera, a first-aid kit, or a set of dry clothes for one person. A 35L or 65L bag holds a tent, a sleeping bag, or a full weekend kit. Measure your kayak hatch before you buy, since a bag that is too wide will not fit through the opening. Round bags pack well in round hatches, while rectangular bags stack better in square hatches.
Are dry bags fully waterproof?
Most roll-top dry bags protect against spray, rain and brief splashes, but they are not made for submersion. A roll-top seal keeps water out when the top is rolled at least three times and buckled. For electronics and other items that must stay dry, double bag them: put the item in a small dry sack, then place that sack inside a larger one. Check the maker guidance for your bag, and do not rely on any dry bag as a flotation device. If a bag goes over the side, retrieve it quickly and check the seal before you open it.
How do you pack a dry bag for a kayak?
Pack heavy items low and near the center of the kayak for balance. Put items you need during the day, such as a rain jacket or snacks, in a small bag near the cockpit. Roll the top of each bag at least three times, then buckle it, and squeeze out extra air before you seal it, so the bag packs flat. Label bags by color or with a small tag, so you can find the right one without opening them all. Keep a repair buckle and a small patch kit in your repair kit, since a broken buckle can end a trip.
What is the best dry bag for kayak camping?
The Sea to Summit Lightweight Dry Sack in 20L is the top pick in this guide for most kayak campers, because it is light, well sealed, and easy to pack. For rough shores, choose the Big River Dry Bag, and for a whole weekend kit, choose the NRS Bill's Bag in 65L.
How many dry bags do I need for a kayak camping trip?
Most paddlers use three to five bags: one for clothing, one for sleeping gear, one for food, and one or two small bags for electronics and valuables. Smaller bags are easier to fit through hatch openings than one large bag.
Can I submerge a dry bag?
No, most roll-top dry bags are not made for submersion. They protect against spray, rain and brief splashes. For electronics, double bag them, and check the maker guidance for your bag.
What does hydrostatic head mean?
Hydrostatic head measures how much water pressure a fabric can resist before water passes through. A higher number means stronger protection. The Sea to Summit bags in this guide list 10,000 mm, which is a strong rating for spray and rain.
How do I keep a dry bag from smelling?
Empty the bag after each trip, rinse it with fresh water, and dry it fully with the top open before you store it. Store it unrolled in a dry place, and do not pack damp gear inside it.
