Endura Men's MT500 Spray Pant Design Philosophy The ultimate do it all mountain biking trouser just got better. The MT500 Spray Trouser is designed to excel in damp, variable conditions. A waterproof, taped seat panel sheds off the worst of the water kicked up from your back wheel whilst unrestricted movement and comfort is maintained by using a durable stretch nylon fabric for the rest of the trouser. Spray Ready Protection Whilst only the seat panel of the trouser is waterproof, a DWR treatment has been applied throughout to help water bead and not soak into the shorts. Clickfast Compatible The MT500 Spray Trouser has Clickfast poppers on the inner waistband which allow you to be securely fix any Endura Clickfast liner shorts inside. Liner shorts all have internal padding providing improved comfort in the saddle.
