LOBOO BWB40T 40 L rear bag, IPX7 waterproof with a waterproof zipper

IPX7 means protection against temporary immersion: it is the highest rating in the LOBOO soft bag range. In practice, it protects against heavy rain for hours, splashes while fording, and accidental washing. The fabric is composite TPU with a water-repellent finish, which prevents the material from becoming saturated with water and heavier. However, this does not mean that the bag can remain submerged indefinitely.

No, and the manufacturer states this explicitly: the two side pockets are not waterproof. The main compartment, which is closed by the waterproof zipper, and the top pocket are waterproof. Documents, your phone, and electronics should go there. The side pockets are convenient for a rain jacket, spare gloves, or a water bottle.

No, it doesn’t have a roll-top closure: it has a waterproof zipper that runs along three sides. Pull it, and the bag opens flat like a book, staying wide open. That’s the biggest practical difference compared with a rolled dry bag: to retrieve something from the bottom, you don’t have to empty everything out or redo the closure. The zipper pulls are easy to grip even while wearing gloves.

Forty liters in the main compartment, in a 55 × 33 × 24 centimeter body. As a general guide, it holds enough luggage for four or five days: a change of clothes, one technical garment, and nighttime essentials. In addition, there are six separate storage spaces: two side pockets, one top pocket, two internal pockets in the lid, and the elastic straps on top for a rain cover, sleeping bag, or sleeping mat.

A sealed dry bag traps air and stays inflated, so the load shifts around and the bag acts like a sail. The valve lets you release the residual air after closing the zipper: the contents become more compact, the volume decreases, and the straps work better. It’s a detail you notice on the first motorway trip.

It’s universal: it rests on the passenger seat, luggage rack, or on top of a top case and attaches to the motorcycle’s anchor points. The manufacturer states that it features a dual fastening system, compatible with both traditional straps and quick-release straps, so it works with what you already have. The buckles are Duraflex.

The BWB40T bag comes complete with its integrated accessories: elastic straps on the lid, Duraflex buckles, a card holder, and a deflation valve. The manufacturer does not specify in the documentation whether loose tie-down straps are also included. If you need them and do not want to take any chances, contact us before ordering and we will verify the actual package contents.

Yes, and it’s one of the uses shown by the manufacturer: the bag rests on the top case lid or on the luggage rack above the panniers, secured to the handles or the frame. At 55 centimeters long, it covers the surface of an aluminum top case well. Just make sure the load doesn’t obscure the license plate or rear lights.

The base has a thickened non-slip layer designed specifically for this purpose: it increases friction against the saddle or luggage rack and reduces slipping when braking. It does not replace proper fastening, but it puts less strain on the straps and keeps the bag from tending to shift forward with every stop.

The BWB56T is the larger sibling in the same series: 56 liters, 63 × 30 × 30 cm, 1.6 kg, and it also features an external MOLLE system for attaching additional pouches, front and rear pockets, and shoulder-carry options. The BWB40T is more compact and lower, so it fits better on the passenger seat without protruding: if you don’t need the extra liters and want a compact size, this is the right one for you.

They have the same IPX7 rating, so waterproofing isn’t the deciding factor. The ALPS 46L has six more liters of capacity and more extensive features, and costs almost twice as much. The BWB40T is the balanced choice for anyone who wants a serious waterproof bag without moving into a higher price category.

The manufacturer does not specify a maximum load for the bag. The limit to observe is the one indicated in your motorcycle’s manual for the luggage rack or rear seat, which for many adventure bikes is between five and ten kilograms. The empty bag weighs 1.47 kg, and this must be deducted from the available load capacity.

Beige shows dirt more than black, but coated TPU is a smooth, sealed surface: mud and dust do not penetrate the weave and can be wiped away with a damp sponge. The most exposed areas, the bottom and corners, are black anyway. That is also why a light-colored bag is more visible at night and in traffic queues.
