A sealed-seam bag that keeps your gear dry without a cover.

The Rhinowalk 30L is built from PVC-coated polyester with sealed seams, so the bag itself is waterproof — you don’t need to stop and put a rain cover on when the sky opens. It weighs 1.63 kg and measures 20.9″L x 8.7″W x 12.2″H, fitting across the back of most bikes. Customers note it survived 2,000 miles on and off road in heavy rain and sun without the straps losing elasticity.

The modular buckle system lets you combine multiple bags into a 2-in-1 or 3-in-1 setup, which is useful if you later add side bags. It packs down flat when empty, and cinch straps compress the load so nothing shifts at speed. At 30 liters it is a direct competitor to the KEMIMOTO below, but the Rhinowalk has a 4 percent lower weight (1.63 kg vs 1.7 kg) and true seam-sealed waterproofing rather than relying on a cover.

The loop-style strap design on the new model can be tricky to mount on a bike without a rear rack — one reviewer noted the old hook straps were more versatile for small seats. Rhinowalk customer service sent free hook straps on request.

The adventure rider who hits unpredictable weather gets a true seam-sealed waterproof bag here — the Rhinowalk 30L works as a tail pack or carry duffel. skip it if you want top-loading access; this duffel-style bag requires unpacking to reach the bottom.

The expandable tail bag that holds its shape even when empty.

The KEMIMOTO starts at 25 liters and expands to 30 liters by unzipping the side panels — useful for a day ride that turns into an overnight. It weighs 1.7 kg and uses an oxford fabric that is tear-resistant and holds its shape whether full or empty, so it never flops sideways on the rack. Reviewers point out it “holds a lot with expandable option” and works on a Can-Am Ryker Rally with a Max Mount kit.

Four straps and buckles make installation universal across large ADV touring bikes, medium street bikes, and urban retro cruisers. The included shoulder strap turns the bag into a backpack when you park. Two outer side pockets give quick access to a water bottle or snack without unzipping the main compartment.

The rain cover is included but the oxford fabric itself is water-resistant rather than fully waterproof — buyers advise using the cover in sustained rain. The anti-reflective strap buckle improves your visibility when other drivers’ headlights hit the bag at night.

Grab this for a medium bike like a Yamaha Bolt — the bag holds shape as a backrest and expands from 25L to 30L as needed. Pass it by if you ride through a monsoon climate; the Rhinowalk 30L above has true seam-sealed waterproofing.

A day-tripper that stays on the rack full-time without looking bulky.

The 20-liter Day Trip bag is designed to live on your sissy bar or luggage rack without getting in the way — it is 15″L x 9″W x 9″H and weighs 3 pounds. That capacity is enough for a couple of shirts, a jacket liner, and a pair of gloves, making it a natural choice for the rider who needs grab-and-go storage for daily commutes and short weekend runs. One buyer mentioned it fits a Vespa GTS 310 rack perfectly, calling it “small for a couple shirts” but good for small items.

The hard bottom keeps the bag from drooping over the sides of the rack, unlike the NR-300 above which is more of a trunk bag. The UltraMax fabric resists UV fading — a previous competitor bag on the same buyer’s bike “warped and turned purple despite garage storage.” Side pockets hold a phone and wallet, and the included rain cover makes the bag fully waterproof when the weather turns.

The 4.8 rating from 255 reviews is the highest in this list, tied with the NR-300. Buyers consistently mention that it holds its shape, mounts in seconds, and looks good on everything from a Harley Breakout to a Kawasaki Versys.

The tank bag that puts your phone in clear view for turn-by-turn navigation.

Unlike the tail and trunk bags above, the TUSK Olympus sits on your fuel tank so your phone or map is always visible through a clear touch-friendly pocket. The 8-liter capacity (8″W x 12″L top, 11″L bottom x 8″H) fits two 16-ounce water bottles, a snack, keys, and a tire gauge — not enough for a trip but perfect for a day on the dirt or tarmac. The internal USB cable port routes power from the bike to the phone pocket so your GPS stays charged.

Universal mounting straps with four clips work on ADV bikes, sport bikes, and cruisers. One owner reported it fits a KTM 390 Adventure “perfectly” and another called it “non-intrusive” on a KTM 890 Adventure R. The included rain cover protects the bag, though shoppers say the bag itself is not waterproof — the cover needs to be strapped tight at highway speed or it can flap.

The phone pocket responds to touch through the clear plastic so you can swipe maps without stopping. A removable internal divider helps organize small items, and a bungee cord on the front can hold a jacket or gloves. At 8 liters it is the smallest capacity bag on this list, but it is also the most specialized for the rider who navigates by phone.

The GPS-reliant rider gets a tank bag with a clear phone pocket and USB charging passthrough here. Leave it behind for overnight trips — this is a day bag only, and the Nelson Rigg NR-300 or Rhinowalk 60L handle multiday loads.

The smallest bag on the list — and the one that disappears best on a dual sport.

At 6.5 liters (10.5″L x 8.5″W x 4.5″H), the Trails End is designed for the enduro or dual sport rider who carries just a tool roll, tube, phone, and a snack. The Molle panel on the lid lets you strap a jacket or a water bottle on top. Inner self-fastening straps keep the contents from sliding around inside.

The UltraMax fabric from Nelson-Rigg gives it the same fade resistance as the much larger NR-300, and the heavy-duty webbing and buckles hold the bag securely to a seat or rack. Buyers on a Honda CRF 300L and a Kawasaki Versys 300 both noted it fits “perfectly” with no overhang. The bag is expandable slightly thanks to a gusseted design, and it includes a rain cover to keep the contents dry.

One buyer managed to mount it on a 2023 Harley Breakout luggage rack and reported it “fits perfectly and looks great.” This bag shares Nelson-Rigg’s lifetime warranty, so if a buckle breaks or a seam splits years from now, you are covered.

The dual-sport and enduro crowd get a bag that stays out of the way and holds just the essentials — it fits a Honda CRF 300L without overhang. Not your bag if you carry more than a jacket and a tool kit; the KEMIMOTO or Rhinowalk 30L are better fits.

The expandable giant that swallows a 2-person tent and a jacket.

The Rhinowalk 60L starts at 40 liters and opens to 60 liters with a double expansion zipper — that is more than double the capacity of the KEMIMOTO and nearly three times the Rhinowalk 30L. At 24.4″L x 12.4″W x 12.4″H and 4.6 pounds, it is built for multi-week touring on a bike with a rear rack. The internal frame uses reinforced steel wire and a PE sheet so the bag keeps a boxy shape even when fully loaded, unlike some duffels that turn into a floppy sack.

The retractable rain cover is rated to withstand 6000mm of water pressure, meaning it can handle a significant storm. Buyers took this bag on a 17-day moto-camping trip and reported it survived with the contents dry, and the seller sent a free replacement rain cover after the original was lost in a storm. Side-access and top-access zippers let you open the bag without unstrapping it from the bike.

Some reviewers noted that the tie-down straps can slip under hard use because the clamp system is not as sturdy as a ladder-lock buckle. Also, the bag gets “very floppy if not full” — the internal frame helps, but a half-empty bag can shift. The elastic helmet lanyard on top was called “useless” by one buyer, but the overall consensus is a durable, well-designed touring bag at a fair price point.

Go for this if you are planning a long-haul camping trip on a bike with a sturdy rear rack — the 60L capacity with steel wire frame keeps a boxy shape at speed. Think twice if your bike has a small rack or no rack at all; a bag this big needs a solid mounting platform.
