Why We Like The Go Jacket

Castelli claims their most versatile layer with the Go Jacket. It keeps out the cold while offering top-notch breathability for our ride. A neutral fit with ample stretch provides extra comfort so we can have full freedom of movement while we pedal, and a large reflective strip across the three rear pockets increase visibility for low-light situations. This is the jersey to do it all and then some.

Not what I expected

I was looking for a nice Gore-Tex jacket shell without any fleece or other warming material. I like to build my own layers and thought this was the answer. Not sure what Castelli is doing with this jacket. After trying it on, I can say I have never had a Castelli jersey or jacket fit this loose around the midsection. It also runs longer in the front than I would like. I'm not looking for an aero fit, just a more fitted cut (such as Gore's C5 offerings). This is more like a club fit. I guess if you carry a little extra around the mid-section, this might do the trick for you. Castelli certainly identified the market opportunity for this type of jacket, but ventured into new sizing that is very un-Castelli like. Didn't work for me so I had to return it.

Castelli sizing is all over the place.

I returned this product before using it
Size Bought:

I wear a medium in most brands, and typically wear race fit items. I am 6ft, and 165lbs with a 40 inch chest. I ordered a large in this item based on their size chart, and figured this would still be tight based on most Castelli sizing. I was wanting something slightly more relaxed for layering for maximum versatility. This fit like an actual American sized large, and was way too big. I understand that this isn't race fit cut, but I could probably wear a small in this item.
