40x20x25CM Underseat Cabin Bag & Foldable Travel Duffel

Flintronic 40x20x25CM Ryanair Underseat Cabin Bag - Black

Excessive airport gate charges for oversized luggage turn low-cost flights into expensive trips. Engineered to match exact 40 x 20 x 25 cm underseat dimensions, this 20-liter travel duffel slides directly beneath flight seats so you bypass extra carry-on fees. Pack clothing, electronics, and toiletries effortlessly into a single compact bag that adapts to flights, gym sessions, and weekend escapes.

Precision Airline Sizing Beats Unpredictable Baggage Penalties

Generic duffels often bulge beyond airline gauges, leaving travelers exposed to steep penalties right before boarding. Built from tear-resistant polyester with water-splashing protection, this structured bag maintains its shape while shielding contents against sudden spills and rain. An included removable leak-proof wet pocket separates damp gym kit or toiletries from clean apparel, outperforming standard single-compartment bags.

Travel-Ready Utility Highlights

• Exact Underseat Dimensions: Fits under flight seats to eliminate unnecessary carry-on fees.
• Detachable Leak-Proof Wet Pocket: Keeps damp towels, gym kit, or liquid cosmetics separated from dry clothes.
• Tear-Resistant & Water-Shielding Weave: Protects personal items against rain, scuffs, and heavy daily wear.
• Versatile Strap Setup: Features fixed carry handles alongside an adjustable, padded shoulder strap for easy transport.

Technical Specifications

Built for Frequent Travelers and Daily Fitness

Stash your flight essentials or post-workout change of clothes inside a bag that transitions easily from airport terminals to locker rooms. The lightweight build folds down small when not in use, making it ideal as a backup tote inside your primary luggage.
