Oumurs Motorcycle Backpack 35L Expandable – Hard-Shell Waterproof with Rain Cover

A durable, aerodynamic 35L expandable motorcycle backpack with a protective hard shell, integrated rain cover, reflective detailing and ergonomic straps for comfortable riding.

This Oumurs motorcycle backpack balances protective structure and everyday practicality. It starts as a 26L pack and expands to 35L with a zipper, holding a full-face helmet, a 14-inch laptop and daily gear while the carbon-fiber-textured EVA shell guards against impacts and wind. Designed for riders who need secure storage, visibility after dark, and a comfortable carry on short trips or daily commutes.

How much gear fits inside and will my helmet fit?

The backpack measures 20.5 x 14.6 x 6.3 inches in standard mode and expands to 35L via the expansion zipper to add volume when you need it. It can accommodate a full-face helmet (note: some off-road helmets require visor removal), a 14" laptop and charging cables plus clothing or tools.

• Standard capacity: 26L; expandable to 35L with zip
• Standard dimensions listed for fit planning
• Holds full-face helmets; check visor fit for larger off-road styles
• Padded internal sleeve fits most 14" laptops

What protection does the hard shell provide while riding?

The shell is molded from EVA with a carbon-fiber texture and reinforced with Oxford fabric for improved impact resistance and scuff protection. Its streamlined shape also helps reduce wind drag when mounted on the rider’s back, keeping contents safer during falls and reducing abrasion from road contact.

• Carbon-fiber-textured EVA hard shell for impact resistance
• Oxford fabric reinforcements at high-wear points
• Aerodynamic profile to minimize wind resistance
• Rigid exterior helps protect electronics and helmet inside

How does it keep me visible and comfortable on longer rides?

Reflective strips are integrated into the pack’s outer panels to boost visibility in low-light conditions, making you more noticeable to other road users. Comfort comes from padded shoulder straps, breathable back panels and a woven waist belt that redistributes weight across hips and shoulders to reduce fatigue.

• Strategic reflective panels for night and twilight visibility
• Padded, breathable shoulder straps and back panel for airflow
• High-density woven waist belt for improved load distribution
• Ergonomic contouring to relieve shoulder and lumbar strain

Is this backpack weatherproof and suitable for other activities?

The exterior is water-resistant and includes a hidden rain cover you can deploy from a top pocket to fully shield the pack during sudden showers. While great for commutes, riding, camping and day trips, it isn’t fully submersible nor intended as ultralight backpacking gear.

• Water-resistant materials plus a tuck-away rain cover for wet conditions
• Not fully waterproof or intended for immersion
• Versatile for commuting, motorcycling, short trips and camping
• Not optimized for ultralight hiking where minimal weight is critical

Who this is for: Riders who want a protective, structured pack that doubles as a daily carry solution — commuters, urban motorcyclists and weekend riders who need helmet storage, laptop protection and improved nighttime visibility without sacrificing comfort. It’s also a good match for anyone wanting a rugged, weather-resistant pack for short outdoor trips; avoid using it for checked airline luggage or ultralight hiking.
