Going on a trip to Hawaii and plan on doing some zip lining and hiking and swimming in same day. How are these shorts as far drying out after being in the water?


Do you have this shorts in size 40

Unfortunately, we are sold out of the size 40 in all colors. I am not seeing any on order from the manufacturer.

Unanswered Question

How dark is the graphite color? They look black in the picture.
One picture from the back shows green zipper highlights, is this on the black or the graphite color? Both black and graphite pictures from the front show no green highlights.

  • Size Bought: 32

Longer length which I like. Thin, stretch nylon type material. All the pockets have zippers including the front pockets. The front pockets don’t seem to be very deep as I find change, keys etc., finds its way out onto the floor when laying down (thus, zipping solves the problem). I had thought these could serve time for mountain biking or bikepacking but I’m not sure how durable the thin fabric would be with any kind of wreck or abrasion (sitting in camp on a rock etc.,). But—for summer hiking and general wear—they are great


  • Familiarity: I returned this product before using it

seem to flair out on bottom hemline,..lil clownish in style..and the color is on the orangey side more then brown..mammut seems to always fall just short on the final design of things...shame
will have to also spend more money for alterations

returned for I noticed and so should you,if ordering,that the sizie chart is hard to navigate,so BackCountry has been great working with me to try the smaller 33-34,then the larger 34-35.

Great shorts

I normally don't spend this much on shorts but I'm glad I sprung for these. By far they are the best I've owned and they are holding up very well from mountain biking to hiking year round. They are very light, stretchy, and thin (but durable). My only complaint would that they are a bit on the slippery side, so you tend to slide around on seated activities (like mountain biking). But its a minor complaint and wouldn't deter me from recommending these shorts.

Great short!

I love Mammut and these shorts are no exception. They are very light, stretch well, and airy. I've fairly large legs and they fit a little more snug around the upper thigh compared to other Mammut pants I own. The zippers are perfectly positioned.

A hidden gem

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I took a chance on these shorts and I'm glad I did! These are truly a hidden gem and may just have become my new favorite hiking/climbing shorts replacing my Arc'teryx Ramparts.

I like the fabric. It is elastic and light. It's probably not as abrasion resistant as the Ramparts but hopefully good enough and the the fabric of the Runbold's don't make the "swish" sound that the Ramparts do.

I also like the cut, design, and details. While the fit is listed as loose, I feel it fits just right in the front and back and really only the legs are loose in my opinion. All pockets are nicely zippered. There is a Mammut logo on one leg and the text "Mammut" on the other.

The legs are a little long. As listed in the description they stop below the knee.

I usually wear 34/30 or 33/30 pants. I picked the large and they fit perfect. Note though that the elasticity of the material may require you to wear a belt. I always do anyway so it's no big deal.

I hope Backcountry will get more of these.

Great review Marius! Thanks!
