When the weather forecast says sunny and 75, but the sky says otherwise, we grab the ASSOS TRAIL Steinadler Jacket T3 as we head out the door for our ride. Built to handle whatever we get ourselves into out there, the front panel is made from a wind and tear-resistant fabric, while the back panel and sleeves are super stretchy for unrestricted movement on the bike and extra abrasion resistant, so we're not snagging trailside brush as we rip down the trail.
