Best Drybag Backpack Buying Guide

Capacity and Size

Drybag backpacks typically range from 5 liters to over 100 liters. A 20L to 30L bag is ideal for day trips, while 40L and above suit multi-day expeditions.

Consider what you’ll carry: a 20L bag fits a change of clothes, lunch, and a small camera; a 40L bag can hold a tent and sleeping bag. For large loads, the Haimont 100L model offers ample space.

Waterproofing and Material

The best drybag backpacks use welded seams and roll-top closures to achieve IPX6 or higher waterproof ratings. Materials like PVC, TPU, or nylon with a waterproof coating are common. For extreme conditions, look for fully submersible bags.

The same waterproofing principles apply to quality rain gear.

Closure System

Roll-top closures are the standard for drybags: they create a watertight seal when rolled down and clipped. Some models also feature waterproof zippers for easier access.

A roll-top is more reliable for submersion, while zip closures are convenient for quick access. Many drybag backpacks combine both, like the Lamicall and Piscifun models.

Comfort and Fit

Since you’ll likely carry a drybag backpack for hours, look for padded shoulder straps, a breathable back panel, and a sternum or waist strap to distribute weight. Some models, like the CRESSI Ocelot, are designed with ergonomic straps for hiking.

For fitness enthusiasts who track their walks, a comfortable backpack that keeps your phone and tracker dry is essential; see our fitness tracker guide for compatible options.

Additional Features

Many drybag backpacks include useful extras: a waterproof phone pouch, daisy chains for attaching gear, reflective elements for visibility, and compression straps. Floating capability is a plus for kayaking and paddleboarding.

The Piscifun and Sunnylon models come with a dedicated phone case. For capturing your adventures, pair your drybag with an action camera.

Durability and Care

Look for reinforced stitching, abrasion-resistant fabrics, and corrosion-proof buckles. A well-made drybag backpack should last for years with proper care. Rinse with fresh water after saltwater use and store it dry.

For storage tips, our umbrella care guide offers advice on maintaining waterproof gear. When not in use, keep your drybag in a cool, dry place; consider an outdoor storage shed for larger gear.

Frequently Asked Questions

How waterproof are drybag backpacks?

Most drybag backpacks are designed to be fully waterproof when properly sealed. Roll-top models can be submerged briefly without leaking. However, no bag is 100% waterproof indefinitely, check the IP rating (e.g., IPX6 or IPX8) for submersion depth and duration.

For heavy rain or accidental drops in water, a quality drybag will keep your contents dry.

Can drybag backpacks float?

Many drybag backpacks are buoyant because of the air trapped inside the sealed compartment. Some models, like the Piscifun and IDRYBAG, are explicitly marketed as floating.

This is a great feature for kayaking or paddleboarding, if you drop the bag, it won’t sink. However, once fully packed with heavy gear, buoyancy decreases.

How do I choose the right size?

Consider the duration and type of activity. For a day hike or beach trip, 20-30 liters is sufficient. For overnight camping, 40-50 liters. For multi-day expeditions, 70 liters or more.

Also think about the bulk of your gear, a sleeping bag takes more space than clothes. The Lamicall line offers sizes from 5L to 40L, so you can pick exactly what you need.

Are drybag backpacks comfortable for hiking?

Yes, many drybag backpacks now include ergonomic features like padded shoulder straps, adjustable sternum straps, and ventilated back panels. Models from CRESSI and Pelican are designed with hiking in mind.

For longer treks, look for a waist belt to transfer weight to your hips. If you’re used to a traditional backpack, look for models with similar ergonomic features.

How do I clean and maintain a drybag backpack?

After use, especially in saltwater, rinse the bag with fresh water and wipe it dry. Avoid machine washing or harsh detergents. Store it unrolled and in a cool, dry place. Periodically check the seams and buckles for wear.

Can I use a drybag backpack for everyday commute?

Absolutely. Many drybag backpacks are stylish and functional for daily use, especially in rainy climates. The Lamicall and geckobrands models look like regular backpacks while offering full waterproofing. They keep your laptop and documents dry.

For a more professional look, consider a drybag backpack that resembles a standard daypack.
