The Mammut Sertig shorts are a lightweight option for use during particularly warm spells. Perforated polyester-elastane stretch fabric is used in sections where a moisture build-up is most common, and we have to say it works fantastically and offers unrivalled breathability. Whilst working hard on steep ground or mountain biking, the Sertig offered great air flow and never felt restrictive or uncomfortable. There are limits to when the Sertig can be worn, the major factor being that they offer no resistance against higher windspeeds, but even whilst on multi-day treks, at 148 grams in a size medium, they can be stored in a pack and are a great choice for lounging around at camp, especially after a warm driech day spent in a set of waterproofs. They are also extremely quick to dry, and we often used the Sertig to have a quick dip in a loch as within minutes of leaving the water they are bone dry again.

The waist band is quite high with a wide stretch adjustment band. Paired with an internal draw string this provides a supportive hold without the need of a belt. It does have to be said that the fit is generous in size, and when worn in size medium they fit much more like a large, so it would be best to drop a size when purchasing.

The Sertig for all their great qualities do lack in a certain area and that is the pockets. The two slit pockets with zippers are quite small and will only just about take a compass or a small Havey Ultra Map. If you do have any items stored in the pockets whilst riding a bike they start to dig into your legs and eventually we just stopped using the pockets for anything, simply opening them up to provide extra breathability. The leg zipper pocket is a tad better for storing items whilst working at camp, but again we found the stretchy fabric meant whatever was stored inside would jingle around and become an annoyance. After using these shorts extensively, we would have probably much preferred Mammut just completely free the Sertig from pockets with a focus purely on breathability and comfort.

Our Verdict

When it comes to choosing a highly breathable, lightweight, and comfortable pair of shorts for use in hot weather the Mammut Sertigs won’t let you down. The stretch fabric offers unrestricted movement and can be used for a wide range of high-paced activities. Quick to dry even when soaked they became a favourite amongst our guides for use not only whilst on the hills but also for a quick dip in a loch. Amongst all that is good about the Sertig’s there are, unfortunately, a few design flaws in the choice of pockets that we believe are unnecessary and could be removed to further enhance air flow.
