Arc’teryx Adan Mountain Running Short | Review

Mountain running short with impressive build quality, super light weight and some neat design touches for fans of the Canadian outdoors brand.

‘Beautifully made medium-length, lightweight running shorts with a light and airy feel, but beware the elasticated inner brief’

Outdoors Magic: Incredibly light, nicely made with some neat design touches. Airy, unrestrictive and fast drying too.

Outdoors Tragic: Elasticated inner brief can chafe. Slightly fiddly drawstring design.

Outdoors Grabbit? Incredibly light, unrestrictive and airy plus beautifully made, but the tight liner brief can ride up and chafe where you don’t want it to.

Note the reflective strip for low-light visibility and the slit for easy movement -
Waistband and drawcord look super neat, but continuous loop cord is fiddly to use -

Adan Short – The Tech

Canadian mountain brand Arc’teryx are masters of immaculate construction, so it’s no surprise that the Adan mountain running short is beautifully put together, neatly articulated and, thanks to a careful choice of fabric, improbably light – just 101 grammes for a medium.

On paper they’re not particularly special, just a medium-length running short with a floating liner, but wear them and you’ll appreciate that a lot of thought has gone into the design.

Adan Short – Performance

It’s no so much that lightness is a major issue with a running short, but go for a run in the Adan Short and you’re immediately struck by the airy, unrestrictive feel – insert joke about naked running here, or rather don’t…

It makes them a great choice on warmer days, but they’re also a boon in showery conditions thanks to fast-drying performance. There’s a single rear pocket that happily takes keys and a gel or bar if needed.

We did have a couple of quibbles. The neatly-made, elasticated draw-cord is a continuous loop rather than a conventional one which makes it fiddly to tie and use – we’d be tempted to add a low-profile cord-grip or simply cut it in two. That said, the wide waist band is comfortable and secure.

Finally, the floating inner brief is quite tight and while it hasn’t quite happened to us yet, has definite taint-chafing potential. Definitely something to be aware of if you’re prone to such things.

Standard issue zipped rear pocket is ideal for keys, cash and maybe a gel or bar –


Light, airy, unrestrictive and really nicely made. We found the Adan short was an ideal length and we had no issue with them rucking up uncomfortably between the thighs. The fabric’s nice too, light without feeling fragile, and wicks and dries well.

Our only issue was with the tight inner short. After the Lycra-like comfort of the Salomon Fast Wing Shorts the edge elastic felt like a chafing incident waiting to happen, though to be fair it never quite did, but if you are prone to under-carriage woes, it might make sense to look elsewhere.
