I was looking for a summer weight long sleeve jersey, and I've found it. I've been out on just one ride with this jersey, and but so far, a big fan.
The folks at SheBeest have women's fit dialed, I purchased a medium and it is exactly how I would expect a medium cycling jersey to fit (I wear a Large in Castelli tops for reference). I have a shorter torso and smaller bust. The sleeve length is just right, back length a bit longer and stays down when riding, front is long enough to cover the top your shorts, and really all around the fit is just right.
There are a few extra details in the design that I really love about this piece. Lots of small reflective hits, extra pockets and even a waterproof center back pocket, love the extra high collar, and really really dig the fabric.
