The Neothermo 1/2 Zip is a lightweight, highly breathable fleece constructed using Polartec Power Grid fabric, providing maximum warmth from minimum weight.
In most sports, it's crucial to lay a good foundation. It's the same with layering, and the Polartec® Power Grid of the athletic fitting Neothermo ½ Zip is the perfect moisture-wicking layer that allows you to still get out in cold, cantankerous conditions and build a solid base.
Marmot's Neothermo 1/2 Zip is made from Polartec Power Grid which has raised channels on the inside of the fabric designed to trap air, making it warmer than you'd expect from it's weight. Highly breathable though warmth is compromised in windy conditions so it will need to them be backed up by a windproof layer.
