Sea to Summit Lightweight Dry Bag — 5L Olive Green, Waterproof Roll-Top with Hypalon Closure

Sea to Summit's Lightweight Dry Bag (5 L, Olive Green) is a compact, waterproof roll-top pouch designed to keep gear dry and organized on backpacking, paddling, biking, and travel adventures.

Built for minimal weight and maximum utility, this 5-liter dry bag combines a PU-coated 70D nylon body with a durable Hypalon roll-top closure and taped, double-stitched seams. The interior is finished in white to help you find items quickly inside the bag, while an oval base and low-profile shape make it easy to stow in packs, kayak cockpits, or luggage. At just 0.11 pounds and measuring 6.6 x 5.5 x 12.6 inches when closed, it offers reliable protection for electronics, clothing, food, and other essentials without adding bulk.

How waterproof and durable is this 5 L dry bag?

The bag uses a polyurethane interior coating and a durable DWR-treated nylon exterior to keep water out. Critical seams are double-stitched and tape sealed for reliable waterproofing, and the Hypalon roll-top closure secures contents when rolled correctly.

• PU-coated 70D nylon body resists abrasion and moisture.
• Taped, double-stitched seams reduce leak risk at joins.
• Hypalon roll-top closure provides a solid water-resistant seal.
• White interior increases visibility so you can locate items faster.

Will this dry bag save space and fit inside my pack or kayak?

Yes—its streamlined, low-profile design and oval base minimize rolling and make stowing easier in narrow spaces. Because it packs flat when empty and is lightweight, it’s simple to carry as spare waterproof storage.

• Compact 5 L capacity fits small electronics, mid-layer clothing, or snacks.
• Oval base resists rolling, helping it sit upright in tight compartments.
• Roll-top closure allows adjustable volume depending on how much you pack.
• Weighs only 0.11 lb so it won’t add noticeable carry weight.

How practical is the bag for field repairs and daily use?

Designed with on-trail repairs and frequent use in mind, the bag features a patent-pending removable buckle that can be replaced quickly if damaged. A D-ring and a base lash loop make attachment and securing simple wherever you travel.

• Field-replaceable buckle can be swapped out in seconds without tools.
• D-ring for clipping to harnesses, kayak deck lines, or pack lash points.
• Base lash loop offers additional secure attachment options.
• Low-maintenance materials tolerate repeated rolls and exposure.

What exactly fits in a 5-liter Sea to Summit dry bag?

The 5 L size is ideal for organizing and protecting small to medium items: a smartphone and charger, a lightweight fleece or rain jacket, camera accessories, or a small first-aid kit. It’s also a practical choice for separating wet or dirty items from the rest of your gear.

• Smartphone, power bank, and cables for electronics protection.
• Light mid-layer or compact rain shell for quick weather changes.
• Food, snacks, or hygiene items kept dry in wet environments.
• Camera lens caps, batteries, or small valuables during paddling trips.
