C5 Thermo Jersey

Whether you're slipping it on alone for a cool, shoulder-season training session or pulling it on under your heavy layers for a ride during the cruelest part of winter, the Gore Wear Men's C5 Thermo Jersey is the key to staying warm and comfortable. It features breathable fabric that manages perspiration to minimize chills as you work up a sweat, and a brushed Thermo lining that traps in heat with a comfortable next-to-skin feel. The close-fit collar keeps your neck toasty, and the form-fitting construction keeps drafts from sneaking in. A full-length front zipper makes getting it on and off a breeze, and allows you to vent if you find you need more airflow mid-ride.

Great Thermal Shirt

I've put it through the wringer

Perfect for fall riding in Vermont. Fits snug. Stretches. Excellent quality. Dries quickly. I wear this under a thin stretch jacket for 55 degree weather. With a base layer for 45 degree weather.

Great fit, plenty warm, but not perfect

I've used it several times
Size Bought:
5' 10"

Bought this to keep me warm in late fall/early spring weather in Chicago (down to around/below freezing with terrible winds), and it's been great. The fit is great and close to the skin - just a step below full-on race cut. But it's not perfect: - The cuffs on the sleeves aren't elastic enough, so there's often a gap between the sleeves and gloves, letting cold wind in - having thumb straps would be an easy fix. - The shoulders need more padding, perhaps wind-proofing them would be great; I found myself feeling very cold there, although my core was toasty. - The collar is incredibly tight and almost makes you feel like you're choking, especially when going hard. - The pockets are tiny and don't stretch nearly enough. Fitting a phone, wallet, and Clif bar in any one of the pockets is a squeeze. Forget about a vest/jacket.

Great Fit, True to Size !

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

I'm 5'9" 177 LBS. I'm not a very thin person like some cyclist, my body type is more on the athletic side since I like hitting the gym very frequently. Have a big chest and decent sized back. I ordered a LARGE SIZE and it fit me perfect. I ordered the yellow jersey, it looks great, was very comfy, kept my body warm and the material was awesome. This jersey is true to size, unlike Castilli where a lot of their attire runs very small.

Too small

I returned this product before using it

I am 6'-2", 200 pounds, 36 waist. I bought an extra large per the chart and comments. The XL size I received I would call at best at Medium, impossible to even zip up. Too bad, it seems like a very nice jersey that I would like. This is definitely not true to size. Even accounting for it is designed to form fit.
