1. Best Overall: Earth Pak Waterproof Backpack 55L

Earth Pak Waterproof Backpack, Heavy Duty Roll-Top Hiking Backpack (55L)

• Capacity: 55 liters

Check Price on Amazon

Why it made the list: Earth Pak calls this pack 100% waterproof, and the roll-top design is the same sealing method used by dry bags. Unlike many dry bags, it adds a padded back panel and a waist belt to take weight off your shoulders. Highly rated by buyers, with thousands of ratings, it is the top rated waterproof backpacking backpack we found.

Highlights:

• Large 55 liter main compartment.
• D-rings and MOLLE loops for clipping gear.
• Includes a waterproof phone case, per the title.

Trade-off:

• No frame is listed, so heavy loads may ride less comfortably than in a framed pack.

Best for: Hikers, paddlers and travelers who need everything kept dry.

OSAH DRYPAK Waterproof Backpack Dry Bag (35L, 55L or 85L)

• Material: 500D PVC with high-frequency welded seams
• Closure: roll-top
• Comfort: ergonomic shoulder straps, breathable back padding, chest belt with whistle
• Storage: inner zip pockets, side mesh bottle holders, splash-proof front pocket, bungee cords

Check Price on Amazon

Why it made the list: It costs less than our top pick and comes in three sizes, so you can match it to your trip. Welded seams and a roll-top closure keep gear dry, per the listing. It is highly rated by buyers, with hundreds of ratings, shared across its sizes, which makes it one of the best rated waterproof backpacking backpack options under $100.

Highlights:

• Choose 35L, 55L or 85L on the listing.

We did not test these packs. We compared weight and packed size, durability and weather resistance, comfort, features for the trail, and warranty and value. Our data came from maker specs, Amazon listing details, and star ratings with rating volume. We only chose packs whose listings call the pack itself waterproof, not just water resistant or sold with a rain cover.

Size & form factor

• 35L: Day hikes and light overnights.
• 40L: Ultralight overnights.
• 45L: Weekend trips with compact gear.
• 50L: A common size for two to three nights.
• 55L: Room for a bulkier bag; the Earth Pak and OSAH sizes.
• 60L: Longer trips or colder seasons.
• 65L: Multi-day trips with more gear, like the SealLine.
• 70L: Extended trips or group gear.
• 80L: Expeditions and winter loads.
• Women's: Packs with shorter torsos and shaped belts; check fit carefully.

Type

• Ultralight: Minimal packs; see our best ultralight backpacking backpack picks.
• Frameless: No frame; none of our three picks lists one.
• Internal frame: Framed packs that carry heavy loads well.
• External frame: Classic frames for big, awkward loads.
• Women's specific: Tailored harness sizing.
• Budget: See our best budget backpacking backpack picks.
• Waterproof: Sealed roll-top bodies that keep water out.
• Hip belt: Moves weight to your hips; key for loads over a few days.

Features worth paying for

• Rain cover: Needed on standard packs, not on true waterproof packs.
• Hydration sleeve: Rare on dry packs; carry bottles instead.
• Hip belt pockets: Handy for snacks; uncommon on dry packs.
• Adjustable torso: Found on framed packs, not these picks.

Weight vs comfort: car camping or backpacking

Waterproof dry packs trade some comfort for protection. For long backpacking trips with heavy loads, a framed pack with a liner may carry better. For paddling, travel and wet trails, a waterproof pack is often worth it. Our best backpacking backpack for travel guide covers travel-focused packs.

Weather & season ratings

Packs have no season ratings. A true waterproof pack handles storms, river crossings and paddling splashes. In heat, sealed fabrics can feel sweaty against your back.

Setup, packing & storage

Roll the top three to four times before buckling, as Earth Pak directs. Pack heavy items close to your back. Dry the pack fully, open, before storing it.

Materials, repairs & warranty

PVC and polyurethane-coated fabrics are fully waterproof and easy to wipe clean. Carry a patch kit for punctures. Check each listing for warranty terms.

How much should you spend?

• Under $100: Roll-top dry packs like the Earth Pak and OSAH.
• Under $200: Branded dry packs with better harnesses.
• Under $300: Portage packs with hip belts.

A waterproof pack keeps everything dry without a cover or liner, and it wipes clean. The best waterproof hiking backpack is ideal for rain, rivers and paddling. The trade-offs are less ventilation, fewer pockets and no frame on most models.

If you want the best waterproof internal frame backpack, note that we found none on Amazon US sold as fully waterproof; a framed pack plus a waterproof liner is the usual workaround.
