Lebanon's weather can turn quickly — sunshine on the coast, a downpour a few minutes up the road. On a motorcycle or scooter you can't duck for cover, and a wet phone, wallet or spare layer ruins a ride. A waterproof dry bag strapped to your bike is one of the cheapest ways to keep the important things dry.

Why a dry bag works well on a bike

  • It's sealed by folding, not zipping. A roll-top has no zip to fail in a downpour or to clog with road dust.
  • It's flexible. Unlike a hard pannier, it takes whatever you give it and rolls smaller when it's half empty.
  • It's light and quick to move. Unclip it and carry it into a café or hotel with the shoulder strap.

What to look for

  • Roll-top closure with a buckle. The most dependable waterproof closure; learn how to close it properly.
  • Sealed seams. Welded or taped seams don't have stitch holes for water to creep through.
  • Attachment points. D-rings or webbing loops are what you'll route straps through. See how to secure a dry bag on a motorcycle.
  • A reinforced base. It takes the abrasion where the bag touches a rack or seat.
  • Sensible size. Bigger isn't better on a bike: a heavy, sprawling load affects handling.

Which size for riding?

SizeGood forNotes
5LDocuments, phone, wallet, tools pouch, spare glovesEasy to strap anywhere; ideal for scooters and short rides
15LRain jacket, spare layer, snacks, small camera kitA day-ride and overnight-essentials bag
30L+Multi-day touringUsually needs a proper rack and dedicated straps

What to pack — and what not to

  • Pack: phone, power bank, wallet, bike documents, a rain layer, a spare pair of gloves, a small first-aid kit, a tyre-repair kit pouch.
  • Don't pack: anything sharp or heavy loose against the walls, anything you need to reach while moving, or fuel.
  • Keep your helmet and riding gear on you — a dry bag isn't a place to store them.

Where the Rihla bags fit

The Rihla 5L suits scooters, short rides and anyone who just needs the phone-wallet-documents kit to stay dry. The Rihla 15L has room for a rain layer and a change of clothes. Both have D-ring attachment points, a reinforced base, and a detachable shoulder sling so the bag becomes a waterproof shoulder bag the moment you park — see our shoulder bag guide.

Frequently asked questions

Can I use a dry bag on a motorcycle?

Yes — dry bags are widely used by riders to keep essentials dry. Strap it securely with several short straps, keep straps clear of the wheels, chain and exhaust, and check it after the first few minutes of riding.

What size dry bag is best for a motorcycle?

For day rides and scooters, 5–15 litres is usually enough. Larger bags suit multi-day touring but affect handling when fully loaded.

Is a dry bag better than a zip bag for riding?

For rain, usually yes: a roll-top has no zip to leak. Zip-based luggage can be more convenient to open mid-ride, but a waterproof zip needs care to stay waterproof.
