The Ss.rallytrekkingJersey with Base Layer represents the absolute pinnacle of Assos’ mountain jersey technology. The rally trekking jersey is light, anatomically pre-shaped and protective. This moisture-wicking top layer is specifically designed to keep you cool when partnered with the included Assos Skinfoil baselayer, which uses moisture to either insulate or cool, depending on outside temperatures.
For its rally trekking jersey, Assos uses a synthetic stretch fabric. This smooth polyester material works to transfer moisture at varying rates. When your body is hot, and your perspiration levels are high, the material reacts by accelerating moisture transfer from your skin to the fabric's surface, where it dries quickly. Inversely, when your body cools down, the opposite results, where the evaporation process slows down, using body moisture as a means of retaining warmth.
Assos includes the appropriately sized skinFoil S7 baselayer with the Ss.rally trekking jersey. This baselayer perfectly complements the jersey. Not only does it augment the jersey’s temperature regulation system, but it adds protection from the sun’s harmful UV rays.
The jersey was made with a regular, body-mimicking fit that follows the contours of your torso. Of course, this jersey, like all Assos jerseys, has been designed to accommodate the body within the cycling position. Accordingly, you'll find that the fit feels tight and oddly contoured while standing. However, the moment that you stretch to the hoods or get into the drops, you'll feel that signature Assos "click," and your ride will be guaranteed to be absent of any bunching, chafing, or pinching.
The back of the jersey is made with an open mesh, which acts as a heat exhaust during hot-weather rides. Because of this, however, it provides less sun protection. Again, Assos urges you to wear this jersey with the included baselayer during rides where the sun is a factor.

Not your normal jersey. This piece is made up of 25 different panels and 6 different textiles, which delivers the perfect design and mobility. The Assos design really stands out once in the riding position. This fit is similar to the old Mangussta or the new Cento and Equipe. I sized the same in them all with very similar fit. It is built with medium weight material, but has thicker material on the shoulders for long days in the saddle with a hydration pack. The back of the jersey is made up of highly breathable mesh that allows for maximum ventilation,which was questionable when I pulled it out of the box...not going to lie. NS.SKINFOIL_SUMMER_S7 that's included is a great addition. Great jersey on and off the road, 3 pockets in the back w/ a zipper and a reflection strip. Please feel free to contact me if you have questions on these or any other Assos products.

Perfect mountain biking jersey
- Familiarity: I've put it through the wringer
- Fit: True to size
- Size Bought: Medium
I had very high expectations for Assos when I heard that they'd be entering into the mountain bike apparel game. My expectations were exceeeded with this jersey! The mesh ventilation the back and shoulders of this jersey is great. Especially for wearing a pack. The fit is tight and race-oriented; but does fit slightly looser than the typical Assos road jerseys. Paired with the base layer that is provided, this is my favorite XC oriented mountain jersey!
Not the normal Assos fit.
- Familiarity: I returned this product before using it
I love Assos. Best bibs and jerseys, no question but this jersey is weird. Fits like club fit stuff. Returning it for the Centos jersey.
