Product Description

Looking for a little extra warmth for your base layer? Go for the I/O Bio Midweight Long Sleeve Womens Zip Top.

The Midweight LS Zip uses advanced yarn technology which creates the softest, itch free, merino wool available. The natural merino fabric is breathable, itch free and does not stink. This piece features a full neck zip to bundle up when it's really cold or draw down for added ventilation

The I/O-Bio Difference:

I/O Bio's advanced yarn technology has created the absolute softest merino. Period. One touch and you understand the difference.

Yarn technology is the most critical element in building functional fabrics with next-to-skin comfort, long lasting wear, and superior washability. I/O's attention to yarn is what sets their products apart from every other merino wool garment. I/O Bio spins their own custom crafted yarns, giving our garments the best quality and consistency possible.
