Alpha hype is real!
This is my first Alpha garment and so far it lives up to the hype. With a merino base layer under it and a wind resistant vest it's quite warm and still super breathable. So far I've used it on spring gravel rides with great success, I'm excited to try layering under a shell next winter.

It's good!
It's kinda wierd, in the best way possible.Incredibly light, very breathable and super warm. It's a great outer layer on less windy days and an ideal midlayer for really cold rides.

Lightest Insulating Layer
The Alpha sweater works exactly as advertised, transitional layer that dries quickly and is lighter than any other insulating layer I own. It comes out of the washer already dry.
