Rhinowalk 35L Waterproof Motorcycle Saddle Bag with MOLLE System
Product description
What it is and what it solves
The Rhinowalk 35L Waterproof Motorcycle Saddle Bag is a flexible luggage solution designed to attach to many adventure and sport bike racks. It combines a robust 1680D polyester exterior reinforced with hypalon for durability with a fully waterproof inner bag, so you can keep gear dry in wet conditions and variable weather. It’s aimed at riders who need extra storage without sacrificing spend and convenience.
How it’s laid out and how it feels on the bike
On the outside you’ll find multiple MOLLE compartments and pockets for organised access to tools, maps, or small essentials. The interior is a seamless waterproof bag that can be used independently if you want to switch from motorcycle luggage to a portable bag mid-journey. The carry capacity is stated as around 35L when folded and up to 45L when fully expanded, giving flexibility for shorter trips or longer expeditions.

Quick-release design: ease of use in the real world
Installation and removal are facilitated by a high-strength nylon quick-release system. This makes it practical for riders who stop for fuel or a quick break and want to detach the bag without fiddling with straps every time.
Safety and visibility


A double-sided reflective logo increases visibility at night, a thoughtful touch for riders who frequently ride in low light. It’s not a luminosity suit against other road users, but it adds a small margin for safety during dawn and dusk rides.

What stands out
- Durable fabric with reinforced corners for wear resistance on rough terrain.
- Waterproof inner compartment keeps contents dry even in heavy rain.
- Space-efficient, with expandability up to 45L when you need extra room.
- Practical organisation via external MOLLE sections, easier access to tools and accessories.
What to watch out for: the capacity is generous, but it’s not a guaranteed fit for every bike rack. The measurements and mounting points should be checked against your specific rack and frame geometry. If your riding style involves very aggressive cornering or heavy, rock‑solid luggage, you might want to test how the bag settles under load.
Who this is for

- Riders who regularly commute or tour on adventure or sports bikes and need extra luggage without a bulky second bag.
- Those who value quick attachment/detachment for city stops or variable weather conditions.
- Anyone who wants a modular system with external pockets for quick-access items while riding.
Who it isn’t for: if you expect a rigid, high-end hard-case alternative or require a perfectly flush, feature‑dense mount on every frame, this bag may feel more flexible than you want. If you regularly ride with extremely light luggage, a smaller capacity might suffice.


When it makes sense to buy
- You’re looking for a versatile, expandable saddle bag that can be used with various racks.
- You want a practical waterproof inner bag that doubles as a standalone carry bag.
- Day trips to multi-weather locations demand quick access to essentials and easy packing changes.

When you might want to hold off
- If you need a rigid, weatherproof hard case to protect fragile gear, this soft bag won’t replace that level of protection.
- If your rack mounting points are unusually shaped or very close to exhaust heat, double-check clearance and fit before purchasing.
What to review before buying
- Confirm compatibility with your motorcycle rack system and check the mounting points on your bike.
- Consider how much you typically carry and whether the 35–45L range aligns with your needs.
- Inspect the waterproof inner bag’s sealing method and confirm it’s truly seam‑sealed for your typical weather.
- Check whether you need additional straps or mounting accessories not included.

Practical use example


Imagine a weekend ride where you encounter rain and varying terrain. You’d pack a light rain shell, a compact toolkit, a spare layer, and a water bottle in the external MOLLE pockets for quick access. If the weather clears, you can expand the bag to its 45L capacity for an extra layer or small hiking essentials, then detach it quickly at the cafe stop to wander with the waterproof inner bag as a separate carry.

Final verdict
Final verdict
If you prioritise flexibility, practical organisation, and a balanced mix of weather protection and expandability for adventure or sport biking, the Rhinowalk 35L saddle bag is worth considering. It isn’t a substitute for a hard case, but for the majority of touring and day-to-day rides, it offers reasonable capacity with sensible features and straightforward mounting. It may not be perfect for every bike configuration, so verify fit to your rack and typical load.
