13.3 inch laptop bag

This 13.3 inch polyester sleeve fits laptops up to 35.5 x 25.5 x 3.5 cm inside. The silver gray fabric is waterproof, splash-proof, scratch-resistant and wear-resistant. A side opening allows quick access while the vibration-proof lining absorbs shock. A detachable shoulder strap and tie-rod belt make it easy to carry or secure to luggage.

Sustained protection on the move

The thickened construction and 360 degree corner guards defend against repeated knocks during daily commutes. Fluff lining adds a soft inner surface that resists abrasion over long periods. Polyester shell maintains its shape and water resistance through continuous exposure to rain or spills. Detachable strap stays secure when the bag is stacked under seats or in overhead bins.

Lightweight thermal and noise profile

At 400 g the sleeve adds negligible weight and no active cooling or noise. The material does not trap heat, so the laptop vents freely while enclosed. External dimensions of 37 x 27 x 4 cm keep the profile slim for tight spaces. Waterproof coating wipes clean without special products.

Questions about this item

Does the polyester material and 360-degree corner protection keep the bag cool and quiet when carried all day?

The bag is a passive polyester sleeve with no fans or electronics, so it produces no noise and generates no heat during extended carry.

What laptop size must I already own for the 13.3-inch internal dimensions of 35.5 x 25.5 x 3.5 cm to fit?

You need a laptop that measures up to 35.5 cm wide, 25.5 cm deep and 3.5 cm thick — typically a 13.3-inch device — to fit the internal compartment.

Will the side-opening design and tie-rod belt work with an older 15.6-inch laptop measuring 41 x 30 x 3.5 cm?

No, the 13.3-inch model's internal space is 35.5 x 25.5 x 3.5 cm, so a 15.6-inch laptop exceeds the width and depth limits.
