When I was first contacted by Vélofrance to write a review of one of their jerseys, I was a little hesitant since I had not heard of the company before. After testing the eos RSX jersey, I'm pleased I accepted. The 100% polyester jersey is light and breathable. On the rides that I wore it, I didn't give it a thought. That's a good thing; I want to be able to think about my ride, not what I'm wearing and this jersey lets me do that. Like most cycling jerseys, it has 3 pockets on the back for storing gels, patch kit, or whatever else you might take with you on a ride. I like to take my phone in a waterproof case and these pockets fit it fine.
I got the jersey in a medium, and while I could probably wear a small, the medium is a nice, relaxed fit for me. The fit and length is very similar to that of Castelli jerseys while the prices of Vélofrance are a bit more affordable. There is no elastic on the sleeve of this jersey, which is good for me since I find the elastic on most jerseys to be too tight. Though I'm sure some riders might like sleeve elastic and miss it, I don't. In fact, the only negative thing I have to say about this jersey is that the zipper is too short. The zipper on the Vélofrance jersey is only 6" (about 15cm) long. I'm sure some might be fine with that, but I prefer a 1/2 to full zip, not just for ease in getting it on and off but I like to unzip it when I get hot on a ride. The short zipper just doesn't provide as much cooling as I like. However, like I already stated, the jersey is very breathable, so this is not a big issue.
I've worn the Vélofrance jersey on 3 hot, 20 mile rides and felt comfortable. On longer rides in this weather, I think would prefer a full zip jersey so I could unzip it. This should be a good jersey for warm weather or even for layering in cooler weather. The length was enough that I didn't worry about exposed skin on my back, but I don't see anything about UV protection on the website, so that may be a concern for some. The mesh panels provide excellent breathability and I like that there is no elastic on the sleeves. It's a good, lightweight jersey, similar in fit and quality to Castelli at a slightly more affordable price.
