The O'Neal MTB Inner Shorts is the high-performance inner cycling short designed for demanding MTB riders seeking absolute comfort and protection during their trail, enduro or downhill rides. Featuring an integrated chamois pad, anti-slip silicone grippers and quick-drying technical fabric, this liner positions itself as the ideal companion under your MTB shorts to maximize your comfort in the saddle, even on the most demanding trails.

Technical Overview and Design

The O'Neal MTB Inner Shorts (manufacturer reference 9996I-328) is part of the technical apparel range from Californian brand O'Neal, a global leader in motocross and MTB equipment since 1970. This inner short has been designed to integrate perfectly under O'Neal MTB shorts thanks to dedicated side attachment loops, but remains fully compatible with most trail shorts on the market. Its figure-hugging fit perfectly follows body contours without excessive compression, while the high-rise back waistband ensures optimal support in riding position. Available in six US sizes (28 to 38, corresponding to European sizes 44 to 54), this liner weighs approximately 370 grams (V.22 version) and is offered exclusively in black with a small discreet O'Neal logo on the left leg.

Comfort Technologies and Materials

• High-density chamois pad: The chamois pad (synthetic suede) offers optimal cushioning on saddle contact areas, reducing pressure points and irritation even on long rides or demanding technical descents.
• Silicone anti-slip system: Strategically placed silicone grippers on the inner thighs prevent the shorts from riding up during effort, ensuring perfect hold and constant stability.
• Technical breathable fabric: Made from polyester (100% according to some versions, or poly/polyamide/polyethylene blend depending on generation), the fabric ensures rapid moisture-wicking, ultra-fast drying and remarkable lightness.
• Mesh inserts on back: Ventilated mesh panels promote air circulation in hot zones, optimizing thermoregulation during intense efforts.
• Zippered pocket at waistband: Practical for securely storing keys, cards or a small energy gel.

Compatibility and O'Neal Attachment System

The O'Neal MTB Inner Shorts features side attachment loops that connect directly to O'Neal MTB shorts (Element FR, Pin It, Generator, Matrix, Stormrider ranges…). This liner attachment loops system allows you to secure the inner short to the outer short, preventing any unwanted movement and creating a perfectly integrated ensemble. Even if you don't own O'Neal shorts, this liner works perfectly as a standalone garment under any MTB shorts thanks to its fitted cut and silicone grippers.

Performance and On-Trail Use

Designed for MTB cross-country, trail, all-mountain, enduro and downhill, the O'Neal MTB Inner Shorts meets the expectations of riders who spend hours in the saddle. Whether you're heading out for a 3-hour mountain ride, a bike park session or an enduro competition, this inner short provides that extra dose of comfort that makes all the difference between a pleasant ride and a memorable day. The quick-drying fabric remains comfortable even with intense perspiration or water crossings, while the chamois pad absorbs shocks and vibrations transmitted from the terrain.

Care and Durability

The O'Neal MTB Inner Shorts is machine washable (delicate cycle recommended) and retains its technical properties wash after wash thanks to the quality of synthetic fibers used. The chamois maintains its cushioning, the silicone grippers their grip and the fabric its moisture-wicking capacity. A hanger loop at the back of the waistband allows optimal drying and storage.
