Openform Merino Hiking Sweater

A very breathable, warm, soft and highly-dimensional superfine merino-rich fabric. Built around a yarn that blends top-capped 17.5 micron merino (65%) with nylon staples (27%) and then wraps them around an elastane core (8%) to create a beautiful combination of soft performance, ruggedness and structural snap. Technically these yarns are knit in a waffle construction, but that heavy elastane snap collapses the fabric to the point where it looks more like a tight rib or even a robust jersey. If you look closely you can still see that waffle structure a three-dimensional openness that allows lots of airflow in motion while insulating well in static conditions. Originally named Warmform Merino and renamed because over the years we’ve realized that while it is warm in the right conditions, its greatest strength is the huge thermal range it offers in active conditions.
