Oumurs Motorcycle Backpack 35L Expandable - Hard-shell Protection, Rain Cover & Reflective Safety

The Oumurs 35L motorcycle backpack is a lightweight, hard-shell riding pack with an expandable 26→35L capacity, built-in rain cover, reflective details and ergonomic support for safe daily riding.

Designed for commuters and weekend riders, this bag pairs a carbon-fiber-textured EVA outer shell with durable Oxford fabric to protect gear from impacts and spray while keeping weight low at 3.3 pounds. A two-stage capacity system and a clear size guide make it simple to pack a full-face helmet, a 14-inch laptop and everyday essentials without bulking up when you don’t need the extra room.

How much can this backpack carry and will my full-face helmet fit?

The pack expands from a standard 26L to a maximum 35L using the expansion zipper, with external dimensions of 20.5 x 14.6 x 6.3 inches at the standard size. It comfortably stores a full-face street helmet; very large off-road helmets may require removal of the visor to fit.

• Standard capacity: 26 liters; expanded capacity: 35 liters.
• Fits a 14-inch laptop in a padded sleeve.
• Front compartment sized for a full-face helmet (visor removal may be needed for some models).
• Compact profile for daily commutes; expansion for short trips.

Is the backpack weatherproof and what protection does it offer riding at night?

The outer shell and Oxford fabric are water-resistant and the pack includes a hidden, pull-out rain cover that fully encloses the bag during sudden downpours. Reflective strips are integrated into the design to increase visibility in low light without adding bulk.

• Built-in rain cover stored under the top zipper for quick deployment.
• Water-resistant construction—not fully submersible or rated for extended heavy rain without the cover.
• High-visibility reflective elements improve nighttime recognizability.
• Aerodynamic shell reduces wind drag while riding at speed.

How comfortable and durable is the Oumurs backpack on longer rides?

At just 3.3 pounds, the pack uses padded breathable shoulder straps and a high-density woven waist belt to distribute weight ergonomically across the torso. The hard-shell EVA front resists impact while the Oxford fabric panels and reinforced seams stand up to everyday abrasion.

• Padded, ventilated shoulder straps reduce shoulder strain on extended trips.
• Waist belt helps transfer load off the shoulders for better balance.
• Carbon-fiber-textured EVA hard shell protects contents from knocks.
• Streamlined contouring limits rider fatigue and improves stability.

What devices and activities is this backpack best suited for?

The internal layout supports a 14-inch laptop, accessories, charging cables and riding essentials, making it ideal for urban commuters and short motorcycle outings. Its combination of protective hard-shell styling and packability also suits general outdoor use such as cycling, day hikes, or weekend trips where tough protection and quick rain coverage are priorities.

• Padded laptop sleeve for a 14-inch computer and tablets.
• Separate compartments for tools, gloves, and small electronics.
• Useful for commuting, riding, light camping, and day travel.
• Not recommended for checked airline luggage or ultralight backpacking.

Who is this for: Riders who want a protective, low-profile backpack that adapts between daily commuting and short trips. If you need a light, impact-resistant pack with quick rain protection and reflective safety details—without the bulk of a dedicated touring bag—this Oumurs 35L expandable pack is built to balance protection, comfort and usable capacity.
