  • Three-dimensional pad equipped with ultra high-density foam inserts to relieve pressure in the ischiatic area when riding in an upright MTB-specific position
  • Antimicrobial carbon threading and laser-perforation in the pad increase breathability and reduce drying time

"The Kitsbow Ventilated Base Short is constructed from Aenergia fabric, which has a greater wicking surface area when stretched. The shorts also have a wide compression band with heat activated grip, and use an Italian made EIT performance Carbonium insert. The pad is MTB specific and uses high density foam inserts to relieve pressure in the ischaitic area when riding in an upright mountain bike style position."

Tight, light and confortable

They are comfortable and, at the same time, sufficiently tight. The touch is very pleasant and aesthetically they are "a pass". The combination of fabrics and racks is very wise. Only one appreciation:: the sizes are very tight. Són còmodes i, al mateix temps, suficientment ajustats. El tacte és molt agradable i estèticament són una passada. La combinació de teixits i ratxetes és molt encertada. Una sola cosa: les talles són ajustadíssimes.


Not trying to be a **** up, but fantastic.

At the risk of sounding overly complimentary this is a great company. I use to buy mountain biking gear from a company in Australia and they went under ( no pun) . Kitsbow is my go to now. Shorts are great .

Wonderfully designed!

These shorts look great and function beautifully! My favorite feature is the front snap closure; it slides and locks!


Excellent quality and fit

Unsurpassed comfort and quality. Fit is a little tight (I usually wear medium and chose size medium in these).

Great Base Short!

These base shorts are incredible. I have never worn base sorts this comfortable. They are very, very high quality. The padding is perfectly positioned. These shorts are made by riders. So happy with this purchase.
