The Montane Men's Slipstream 5" Trail Running Shorts are designed for fast-paced trail runs, intervals and warm-weather races where lightweight, freedom of movement and secure storage are essential. With a 5" (12.5 cm) inseam and a run-specific, tailored fit, they offer the optimal balance of coverage and maximum mobility.
The outer fabric is made of AEROFLYTE QD stretch polyester , an extremely lightweight, durable and quick-drying material that effectively wicks away moisture during high-intensity workouts. The breathable Apex Dry mesh inner brief provides close-to-the-body support and is treated with POLYGIENE® permanent odor control , helping to keep you feeling fresh even on longer, sweatier runs.
The waist has a stretchy waistband with an internal drawstring that keeps the shorts securely in place on technical terrain. Storage is cleverly integrated for trail running: gel-shot pockets at the back provide quick access to energy, while a rear YKK zipper pocket secures keys or cards without bouncing. Reflective details on the front and back improve visibility when running in low light.
Weighing in at around 105g (size M) , the Slipstream 5" is a natural choice for runners who want performance without unnecessary bulk – perfect for everything from short tempo runs to long, hot trail adventures.
