The GORE Bike Wear POWER Thermo Jersey provides good insulation, excellent build quality and a few reflective elements, but at a fairly high price.
Made from a medium thickness nylon/elastane mix fabric, with a nice soft and brushed inner side, this jersey provides plenty of warmth. It is quite stretchy, so it will follow your curves well without any flapping. Being so close to the skin, it wicks moisture well. Since it is not windproof, it is highly breathable so there is a bit of windchill when worn alone.
The front is simple with a V-shaped reflective piping and a full-length zip. The neck collar is high and close fitting and prevents cold air from getting inside. The back goes a bit lower then the front, featuring 3 pockets and a rubber gripper to prevent the jersey from going up. There are two reflective lines following the middle pocket.
The sleeves are quite long like any other long sleeved jersey or jacket from GORE. I am 188cm with slightly long hands and size Large fits me perfectly. There is also a short reflective line on the back each sleeve.
Although it is not windproof, the POWER Thermo Jersey is quite versatile. During the first autumn days I used it only with a sleeveless summer base layer. Then, when it got colder, I added a windproof vest on top of it and I was OK until the temperatures dropped below 15°C. Depending on how good is your blood circulation, you will forget about this jersey until the temperatures drop even further around 0-5°C and even below zero. Then, when used as a middle layer it provides excellent warmth and moisture transport and enables you to go as far as -5°C with a jersey like windproof top like the Endura Convert Softshell Jacket and even lower with a proper winter jacket.
Pros: Good fit, nice fabric, reflective elements, build quality, versatile
Value: 7/10, Nice but pricy
