What they say: This Gore Windstopper long-sleeve base layer will keep the wind off your core, allowing you to perform better in the worst weather conditions.
What we say: Keeping warm is about more than just wearing enough, it’s wearing the right things, too. Wind-stopping base layers, like this one from Gore, are a handy cheat. The windproof membrane on the chest stops wind-chill from getting to your skin so it keeps your chest from getting too cold. But it’s highly breathable, too, so will allow you to cool quickly should you heat up. It comes in five sizes, black or white as well as a short-sleeved option.
Conclusion: A great choice for rides where weather is changeable and climbs/ descents are long.
