Description 30 L IPX6 Waterproof Motorcycle Saddlebag | rollable and foldable, 2 quick-release straps included

The LOBOO BWB30 foldable waterproof bag is the bag you take on board empty. Folded, it measures 29.5 × 12.5 × 6 cm and fits inside a top case, pannier, or backpack; when opened, it provides 30 liters of extra capacity for luggage you picked up on the way back or for keeping dry anything that does not fit in your cases. It weighs 479.5 grams.

Why choose this LOBOO product

  • Capacity when you need it. Thirty liters is a weekend's worth of clothes, a sleeping bag, or everything you bought while traveling. When you do not need it, it takes up hardly any space: the bag folds down to the size of a large pencil case.
  • Nylon laminated with a TPU membrane. The manufacturer states that it uses high-quality nylon resistant to abrasion and tearing, with a waterproof TPU film: the fabric itself provides the barrier, rather than a surface treatment that wears off.
  • Roll-top closure. The edge rolls over itself and closes with buckles. This system keeps out continuous rain better because it has no zipper through which water can work its way in.
  • Duraflex buckles. The manufacturer states that the buckles are made by US brand Duraflex, the same standard used on technical backpacks. Buckles are the first part to break on a motorcycle bag, and these are not generic.
  • High-visibility reflective strips. Integrated into the securing straps. At night, with the luggage at the rear, the motorcycle is seen sooner.
  • Two colors. Black and military green, at the same price.

What is included

  • 1 × 30-liter BWB30 foldable waterproof bag
  • Quick-release nylon fastening straps

The bag arrives folded inside its mesh storage pouch.

How it folds

The manufacturer documents five steps: lay the bag flat with the mesh pouch turned inside out, fold both sides toward the center, roll it from the bottom upward, and place everything inside the pouch. The result is a 29.5 × 12.5 × 6 cm package.

Compatibility

It is a universal product: secure it with the straps to the anchoring points already present on the motorcycle, over the passenger seat, on the luggage rack, or on top of a top case. It does not require dedicated mounting hardware and has no model-specific restrictions.

Usage limitations

The manufacturer warns that the external zippered pocket only offers splash protection; it is not waterproof: documents, phones, and batteries should go in the main compartment. The main compartment is protected by the TPU membrane and the roll-top closure, but LOBOO does not state any IP rating for this bag: it is designed for rain and splashes, not immersion.

The technical data are those stated by the manufacturer. Before setting off, check that the fastening does not cover the license plate or rear lights and that the load complies with the limits of the Highway Code.

Why choose it
  • Foldable:folds away in seconds and takes up very little space in your top case or backpack.
  • IPX6 Waterproof:heavy rain and high-pressure splashes won't get in.
  • 30 L Main Compartment:true capacity despite minimal bulk when the bag is closed.
  • Durable Nylon:resistant to abrasion and wear, with quick drying.
  • Two colors:Army Green and Black.
Who is it recommended for

It's the bag you keep on board empty. It's useful if:

  • When you return, your luggage grows, and you need unexpected extra volume
  • You want a dry bag to attach on top of your side panniers only when it rains
  • You travel light but don't want to give up a waterproof space reserve

If you're looking for the main rear bag for long trips, consider the 40L Waterproof roll-top, the ALPS 46L IPX7, or the Wanderer 50L.

Documents and manufacturer

Usage and notes

  • Degree of protection declared by the manufacturer: IPX6, protection from high-pressure water jets. Not intended for submersible use.
  • Always secure the bag with straps or elastic cords to the motorcycle's anchor points, checking the tightness before departure.
  • The load must not obstruct the license plate, tail lights, or protrude beyond the limits set by the Highway Code.
  • Fastening straps not included unless otherwise specified.

What does it look like in detail?

Thirty liters that appear only when needed

Thirty liters that appear only when needed

The problem with luggage on a motorcycle isn’t how much fits on the way there; it’s how much fits on the way back. The gift you bought halfway there, the sweater you were wearing that morning, the groceries for dinner at the campsite.

The BWB30 solves this by adding thirty liters when you need them. It’s a backup bag, not a second piece of luggage to carry around empty.

Folds down to fit in one hand: 29.5 × 12.5 × 6 cm

Folds down to fit in one hand: 29.5 × 12.5 × 6 cm

When folded, it is a package measuring twenty-nine and a half centimeters by twelve and a half, and six centimeters thick. Four hundred seventy-nine and a half grams. Those are the dimensions of a large pencil case.

It lives at the bottom of a side pannier all year round without you noticing, and that is the point: you never carry a bulky backup bag.

Folds in five documented steps

Folds in five documented steps

Lay the bag flat, turning the mesh pouch inside out, fold both sides toward the center, roll it from the bottom upward, and place the bundle in the pouch.

There’s no technique to learn, and you don’t need to force the air out with your knees: the pouch is sewn to the bag, so it won’t get lost or need to be searched for.

It fits inside the luggage you already have.

It fits inside the luggage you already have.

Aluminum pannier, top case, waterproof bag, or backpack: when folded, it fits anywhere, even in the lid’s elastic net.

That’s the way of traveling it was designed for: set off with the luggage you need, while the spare stays put until the plan changes.

Nylon selected for abrasion and tear resistance

Nylon selected for abrasion and tear resistance

The manufacturer states that it uses high-quality nylon, selected for its resistance to abrasion and tearing. These are the two real stresses on a bag strapped to the rear of a bike: friction against the luggage rack and tension from the straps at the attachment points.

The ripstop weave limits the damage if a cut occurs: it does not spread across the entire fabric.

Roll-top closure and TPU membrane

Roll-top closure and TPU membrane

Waterproofing comes from the fabric, not a surface treatment that wears off: the nylon is bonded to a TPU film. The opening rolls down on itself and is secured with buckles.

It is the system that holds up best in continuous rain because there is no zipper on the main compartment through which water can seep upward. LOBOO does not claim a certified IP rating for this bag, and we prefer to be clear about that: it is designed for rain and splashes, not submersion.

Retaining straps with reflective strips

Retaining straps with reflective strips

The outer straps guide the belts and prevent the load from shifting. Each one has a high-visibility reflective strip sewn onto it.

At night, with luggage at the rear, that is the most visible part of the motorcycle: two strips reflecting headlights can make the difference between being seen from a hundred meters away or from thirty.

Duraflex buckles have a limit you should know about

Duraflex buckles have a limit you should know about

The buckles are Duraflex, an American brand that is the standard for technical backpacks. On a motorcycle bag, they are the first part to give way, and these are not generic.

A warning the manufacturer states explicitly and that is worth reading before purchasing: the external zippered pocket only protects against splashes; it is not waterproof. Phones, documents, and batteries should go in the main compartment.

Black or olive green, same price

Black or olive green, same price

The two versions are identical in terms of material, volume, weight, and included features. The body color and the color of the details differ: gray zippers and reflective elements on the black version, and contrasting yellow ones on the military green version.

Those who often load it in the dark or among their luggage may find the green version slightly easier to spot at a glance.

It attaches to the motorcycle you already have

It attaches to the motorcycle you already have

On the luggage rack, passenger seat, or top case lid: all you need are points for threading the straps through. No dedicated mounting system, no drilling, and no brand or model restrictions.

The manufacturer shows it mounted on a BMW GS, Honda Africa Twin, and KTM Adventure, but it works with any motorcycle: the geometry of your load—not the model—determines the fit.

FAQs

For more information, please see our FAQ.

How much space does it take up when I’m not using it?

Folded into its mesh case, it measures 29.5 × 12.5 × 6 centimeters and weighs 479.5 grams. It takes up about as much space as a large pencil case: it fits at the bottom of a side pannier, inside a top case, or in a backpack without taking up valuable space. That is precisely why this bag exists.

How does it fold, and how long does it take?

The manufacturer documents five steps: lay the bag flat with the mesh pouch turned inside out, fold both sides toward the center, roll it from the bottom up, and place the bundle in the pouch. With a little practice, it takes less than a minute.

Is it really waterproof? What level of protection does it provide?

Yes. The main compartment is made of nylon bonded to a waterproof TPU membrane and closes by rolling the edge, without zippers through which water could seep upward. The manual specifies the IPX6 rating under one precise condition: the roll-top edge must be folded three times and the side buckles must be fastened. With only two folds, the seal does not meet the stated rating. IPX6 means resistance to powerful water jets, not immersion.

Can I put my phone and documents in the outer pocket?

No, and the manufacturer itself points this out: the external zippered pocket only offers splash protection; it is not waterproof. During continuous rain, water gets in. Documents, your phone, batteries, and chargers should go in the main compartment, which is the one protected by the TPU membrane and roll-top closure. The external pocket is handy for a rain jacket or a spare pair of gloves.

Are the fastening straps included?

Yes, and there are twoThe accessory list in the manual includes the bag and two quick-release straps. They attach to four fixed points on the top case lid or luggage rack; secure the excess webbing with the Velcro to keep it away from the wheel and chain.

How is it attached to the motorcycle?

With the quick-release straps, attach it to the motorcycle’s existing anchor points: passenger handles, luggage racks, pannier frames, or over the lid of a top case. No dedicated mounts or drilling are required. The securing straps on the bag have dedicated loops and incorporate reflective strips. Always check that it is secure before setting off and halfway through your journey.

How much can it really hold?

Thirty liters, in a bag that measures 50 × 30 × 20 centimeters when unfolded. As a rough guide, that’s enough for a weekend’s worth of clothes, or a compact sleeping bag with a sleeping pad, or everything that accumulates during a trip and no longer fits in your suitcases on the way home. The manufacturer does not specify a maximum load weight.

How much weight can I load onto it?

The manufacturer does not specify a maximum load for the bag. The practical limitation is not the bag but the motorcycle: your motorcycle's manual indicates the maximum permitted load on the luggage rack or rear seat, and that is the limit to observe. In practice, a 30-liter spare bag fills up in terms of volume, not weight.

Can it also be used outside the motorcycle?

Yes. The manufacturer also presents it for hiking and outdoor sports: the waterproof main compartment and roll-top closure work just as well on a boat, while camping, or in the snow. Away from the motorcycle, the real convenience remains the same: carry it folded and open it only when needed.

What’s the difference between black and military green?

Only the color differs: the material, volume, weight, and included features are identical, as is the price. On the military green version, the zippers and reflective strips contrast in yellow; on the black version, they are gray. Those who often load it in the dark may find the green slightly easier to see at a glance.

Will it work for my motorcycle?

Yes: it’s a universal product, with no brand or model restrictions. The only requirement is having points through which to pass the straps, which are present on any motorcycle with passenger grab handles, a luggage rack, or side racks. On a motorcycle without a passenger seat or luggage rack, a support surface is needed, such as the lid of a top case.

Is this better, or should I get a 40- or 50-liter rear bag?

They meet two different needs. A 40- or 50-liter rear bag is the main luggage: it stays mounted, has a stable shape, and carries the load for the trip. The BWB30 is a backup: it travels empty and folded, and only opens when you really need the extra capacity. If you’re looking for the main container, check out the 40 L roll-top rear bags or the 50 L Wanderer. If you’re looking for an extra thirty liters that won’t get in your way when you’re not using them, this is the right one.

Do buckles and stitching hold up at highway speeds?

The manufacturer states that it uses US brand Duraflex buckles, the standard for technical backpacks, and nylon selected for its resistance to abrasion and tearing. These are the two parts that fail first on a motorcycle bag. That said, stability at highway speeds depends above all on how you secure it: straps kept taut, a compact load, and no loose flap that could billow in the wind.
