This piece is a must for winter cycling
No more layering with multi base layers - this one is the only base you need and has wind protection on upper chest and higher collar - but beware - its a tight squeeze to get on and take off but well worth it - Spatz is pricey but its quality and well worth the spend

Basez extreme winter base layer
Best base layer ever. High neck is great, arms are great. Really can’t fault this.
