Spatzwear Basez 2 Black Long Sleeve Baselayer Totally re-engineered, BASEZ 2 is the most technically advanced base layer ever developed for cycling. Built from scratch and rigorously tested by the current Olympic Champion, it’s designed to keep you warm, dry and comfortable in the harshest conditions—without bulk.

Key Features: High neck to block cold air. Thumb loops to seal glove/jacket gaps. Extended rear panel to cover and insulate your kidneys and lower back. Zoned fabric thicknesses to offer warmth and moisture management exactly where your body needs it.

Worn directly against the skin, BASEZ 2 traps warm air while wicking moisture away. Each panel is tailored for its specific function—thicker on the chest and front of the arms to guard against wind-chill, lighter where breathability is key. The extended neck eliminates drafts and keeps the collar area warm and mobile.

 “The most important garment is the one next to your skin. I spent years riding as a pro, cold and wet even in premium kit. So I designed BASEZ 2 with dedicated yarns and weaves to target the real thermal and moisture demands of each body zone. Nobody had done this properly before. This base layer changes everything.”
There’s nothing else like it. Revolutionary comfort and performance for winter cycling.
