The Flylow Mateo Men's Fleece is a full-zip grid-fleece midlayer that breathes as hard as you do. Made from a comfortable, temperature-regulating fleece, it adds warmth under a shell on storm days and works on its own when the sun comes out. It is the everyday layer that quietly does a lot of work.

Why we like it:

The hard-faced grid fleece is the standout; it regulates temperature well, lets off steam when you heat up, and resists the wear of pack straps. Thumb holes and zippered pockets make it ski-ready.

Features and Functions:

The Mateo Fleece is built from Furano grid fleece, a 90 percent polyester, 10 percent elastane fabric with a taffeta backing, designed to be breathable and quick to vent heat. A full-zip front, a 2.5-inch collar, zippered hand and chest pockets, and thumb holes make it a versatile ski midlayer.

Fit and Sizing:

A regular fit layers cleanly under a shell and over a baselayer. True to size, with a length that stays put when you move.

Bottom Line:

As a breathable midlayer for storm days or a standalone layer for cool weather, the Mateo Fleece is best at temperature-regulating warmth. A hardworking grid fleece for the whole season.
