Learn how to wear, use, and care for the BN3TH Pro Ultra Liner Short with Pocket on the bike. Step-by-step tips for comfort, storage, and washing.
Quick Answer
Wear the Pro Ultra Liner Short with Pocket as a base layer under your cycling shorts, use the rear pocket for small essentials, and follow the care steps to keep it performing ride after ride.
Why Use a Liner Short for Cycling
A liner short with a built-in pouch and chamois padding provides support and moisture management under your favorite cycling shorts. The Pro Ultra Liner Short is designed for high-output activities, making it a versatile choice for both road and mountain biking.
The rear pocket adds convenient storage for keys, a card, or energy gels without needing a jersey pocket. This can be especially useful on shorter rides where you want to travel light.
Choosing the Right Size and Fit
A proper fit is essential for comfort and performance. The liner should feel snug but not restrictive, with the pouch providing support without shifting. Check the size chart and consider your usual underwear size as a starting point.
Because the Pro Ultra is designed for maximum training and elite performance, it has a compressive fit. If you prefer a looser feel, consider sizing up.
Step-by-Step: Using Your Liner Short for Cycling
- Put on the liner as a base layer: Wear the Pro Ultra Liner Short directly against your skin, just like underwear. Ensure the pouch is positioned correctly for support and the liner sits smoothly without bunching. Check that the liner seams lie flat before adding your outer shorts.
- Layer your cycling shorts over the liner: Pull your regular cycling shorts or baggy shorts over the liner. The liner should not be visible, and the waistband should sit comfortably without digging in. Avoid wearing anything between the liner and your skin to prevent chafing.
- Use the pocket for small essentials: Store a key, card, or energy gel in the rear pocket. Keep items flat and minimal to avoid discomfort while pedaling. Don't overload the pocket; it's meant for small items, not phones or tools.
- Adjust for your ride: If you're on a long ride, take a moment to adjust the liner and shorts at the start to ensure everything stays in place. Re-adjust as needed during breaks. A quick adjustment at rest stops can prevent chafing later.
- Wash after every ride: Machine wash the liner in cold water with like colors and hang to dry. Avoid fabric softeners and high heat, as they can break down the moisture-wicking fibers. Proper washing keeps the liner fresh and extends its life.
