C3 Thermo Jersey

Thermal, long-sleeve jerseys are an ideal layer to help resist the chill in the air of the changing seasons. The Gore Wear C3 Thermo Jersey's brushed fleece lining provides essential warmth as an exterior layer in chilly weather and adds insulation to a heavier winter jacket when the ground begins to freeze. Gore moves the chest zip-pocket to the rear on the main pocket panel and boosts reflective detailing in this updated version. The C3's active fit reduces wind-flap on breezy days and downhills and helps reduce bulk if the jersey does need to double as an under-layer for wintry, alpine descents.

  • Zippered rear pocket replaces the front-chest pocket

Great fit, great look, great function!

I've used it several times
Size Bought:

Bought this late winter to wear in early spring and mid to late fall in the NE US. Have worn it a few times this spring and very happy with the fit and warmth. I like having my neck covered and this does the job. High quality zipper. Because it is high vis yellow and recommended to wash with like colors, I always wash alone on cold and dry alone on gently.

Perfect Jersey!

I've put it through the wringer
Size Bought:
6' 73"

I absolutely love when a product supports its description and dedicated purpose! It’s a jersey, not a jacket!, and it does exactly what it supposed to do. Keep you warm and protected. No-not from a hurricane-duh. Coldish mornings/evenings,45-50 degrees. mild wind, cloudy day. It’s perfect. (For me) is true to size. M-US/L-EU is exactly my size. Other brands fit tighter, their “M” and is too tight. Not this jersey. M-is a real M. Great quality and tailoring. Zipper closes and opens perfect. Pockets have plenty of room. And the yellow color is more than visible. I have no idea how other (reviewers) riders found anything wrong to complain. Not me. It is absolutely perfect. If you need a great warm quality jersey, this is the one!

Fit was fine

Size Bought:
5' 7"

I tried on a L and M. The medium was a bit tight but fine if you want an aero fit. The large was more my preference; form fitting but a bit looser everywhere. I had on a thin base layer when trying on both. The quality is good with a nice thin thermal layer which was comfortable and should be warm. Zip pocket is a nice add. I am 5'7" and about 160 lbs. My chest is about 39-40 with 32 arm length. Looking forward to riding with this jersey in the cooler temps. With another comparable Gore jersey I wear a base layer and a jacket when in the high 30's to 50 degrees..

Tried it on, Fit was off

I've used it once or twice and have initial impressions

I've been pleased with other Gore Wear products, however, this instance of their C3 Thermal Jersey is a bit off in its proportions. I'm fairly lean and have been a solid "Medium" with many other lines. Here, to get the jersey zipped up I had to stretch it together making an uncomfortably - sausage casing, tight fit. A Large might have worked for a roomier mid-section - which I have no roundness to speak of, but the body length and arms would be too long. Guess one should be a little wary of clothing that is not modeled on a human being.

Great for a cool ride

Size Bought:
6' 1"

I got this for the upcoming Fall/Winter rides, it hasn't been there temperature wise yet, but upon trying it on it seems true to size L. Wear it with a base layer and I think I'll be good to go. Material is good quality.

Nice quality; very strange sizing

I returned this product before using it
Size Bought:
5' 11"

Upon opening, this appeared very well made but proved to be some of the strangest sizing I've yet experienced in cycling clothes. And the sizing chart for this product is wayyyy off. First, I ordered an XL (USA) based on the size chart (I'm 5'11" and 170 with a 41" chest and boxer-type build). The thing was massive - it would've fit a 46" chest with arms to match easily. I returned it right away. I then meant to replace it with a L, and mistakenly ordered a M. (So, don't multi-task when ordering cycling gear!) I tried it on anyway and the body actually fit perfectly, but the arms were still huge! So, that's going back too. If you have arms ridiculously out of proportion to your body, this might work for you. Or, maybe this was meant for cycling orangutans?
