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.

Montane Men's Slipstream 5" Trail Running Shorts feature Run Fit - a running-specific, flexible fit designed for freedom of movement. The model has a wide elastic waistband with internal drawstring and a supportive mesh inner pant.

The shorts are normal in size. Please base your waist measurement on your size.

Size chart

The measurements refer to the recommended body measurement around the waist.

The leg length is approximately 5 inches, equivalent to 12.5 cm , measured along the inside of the leg in size M. Minor variations may occur between sizes.

How do you measure?

Waist: Measure around the natural waist where the waistband of the shorts will sit. Keep the measuring tape horizontal without pulling it tight.

Hip width: Measure around the widest part of your hips and seat. The hip measurement is especially important if you have a fuller seat or thighs.

Inseam: Measure from the crotch along the inside of the leg. The 5 inches in the model name describes the approximate leg length of the shorts and does not affect the waist size.

What size should I choose?

Choose the size whose stated waist measurement is closest to your own.

• Choose your usual size for Montane's intended body-hugging Run Fit.
• Choose the larger size if you are between two sizes.
• Go up a size if you have a fuller seat or thighs and want more room in the inner pants.
• The internal drawstring allows for a slightly roomier waist to be adjusted.
• Don't choose a smaller size just to make the shorts fit more securely – the inner brief should provide support without cutting in.

The shorts should sit securely at the waist without slipping, but the waistband and inner pants should not press or restrict your stride. Feel free to try lifting your knees and taking a few longer steps to check your freedom of movement.
