The MerinoLOFT Helix Zip is one of Icebreaker‘s warmest and most sustainable layers ever. This form-fitting, super-lightweight mid-layer can also serve as a standalone sweater in fall or spring weather. The insulation is Icebreaker’s new MerinoLOFT, a recycled material that delivers plenty of warmth with minimal bulk.

The recycled polyester exterior is durable and water-resistant, fending off light precip, while the Merino wool lining maximizes warmth, breathability, and stink control.

Also available in hooded, vest and 3/4-length versions. ca.icebreaker.com
