Nolan B.wrote a review of Gore Bike Wear Oxygen WindStopper Long-Sleeve Jersey - Men's on November 11, 2015
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
I used this for the first time for my commute today. Mid-30s in the morning and low-60s coming home. In the morning I used it as a middle layer and it fit comfortably over a long sleeve base layer. Very comfortable. Coming home I used it as the outer layer and it absolutely stops the wind on the chest. The collar is comfortable and snug but not tight around the neck, so no noticeable breeze down the back.
The sizing runs small (IMHO) and if worn with a base layer could be extremely tight. It is a narrow fit, though stretchy, and a bit short in length for a long torso. The design does easily cover the back when leaning forward.
Highly recommend, but consider getting two different sizes and send one back.
