Bad fit

I've used it once or twice and have initial impressions
Runs large
Size Bought

Similar to another reviewer's experience, this was an ill-fitting jersey: too snug around the shoulders and very baggy around the midriff. Definitely not for those with an "inverted pyramid" type upper body. My cheap Chinese jersey fit much better than this one. The material was also fairly beefy, not something I'd appreciate on hot days. The only appeal is the style and color. I purchased the Orbit Blue jersey. The website shows a white zipper, but the zipper of the actual product was black.

Stylish but really weird fit

Love the look and quality of the jersey but the fit is really weird (Lg). It fits great on my shoulders, neck, and arms but it's kind of baggy around the waste\stomach area. It feels like I could size down (Md) but having done so, the neck was so tight and constricting that I went back to a large. The back of the jersey sags as well because of this design. When you carry a few items in the pockets it hangs pretty low. I also found the fit to vary between the jerseys. I bought 3 of these in different colors at different times. The first 2 fit fairly well (considering) and the 3rd was a bit more loose than the others around the stomach. I would definitely follow the size chart and take your measurements to ensure you get the right size or as close to it as possible. I fit closer to the medium side but found the top of the jersey to be too constricting in that size where as the large fit right at the top but weird at the bottom.

Good value but could be better

I've used it several times
True to size

Bought on sale for $74.95. Fit for me was accurate and no issue with chafing or bothersome edges of the jersey so far. Probably will need more use to comment on whether the breathability could be better. An area that I wish was better was the pocket depth in the back, where it's a bit shallower than other brands. If you're carrying clothes tucked into the back it'll bulge out much more because of the extra fold to make sure it doesn't fall out. I understand C5 is the mid-tier between the C3 and C7 lines but not feeling much of a difference in product quality or performance.

Orbit Blue = Dark Blue

I returned this product before using it

I was expecting the Orbit Blue to look similar to the bright blue color that was shown online. It was essentially a blue variant to the black jersey with a dark blue primary color with medium blue stripes.

I usually wear an xl. But this jersey is running small. So buy one size up.

Too big and not breathable enough

I've used it several times
Runs large

Definitely not form fitting - more of a semi-club cut. I've bought other Gore shirts labeled form fitting - this is bigger than expected. The material feels cheap - it's not breathable and it doesn't handle moisture well. I expect shirts to be damp after a hard enough ride in summer heat, but not literally dripping with pools of accumulated sweat around contact points. It's basically a cheap running shirt with a zipper on the front and a pocket in the back

Like, but not Love

great material, breathes well, and layers nicely, but it kind of fits funny, not sure if i need to go a size down? I run an XL in all my tops from everyone, but seems like i could go down a size? it just fits funky in some areas of my chest and lower back. but perfect everywhere else. So i feel like its more of a funky cut vs too big. anyways its a great jersey other than that.

Can you measure the zipper length on the back pocket. I was going to see if my phone fits in it.
