For high energy adventures in the winter I love fleece layers. They just breath better than anything else and can stand up to tons of use. This winter I picked up a Mountain Hardwear Monkey Man II Grid Hoodie. And I have been wearing it so much I bought a second! That should tell you about how much I like this piece.
The Monkey Man II has stretch panels on the side and hood, the collar goes up really high and it has a roomy hood. I have used it as both an outer layer and under a coat on crazy cold days.
The grid material is Polartec High Loft, and I have to say it is the warmest and softest fleece I have owned. This has been my go to for fat biking, running and mountaineering this winter.
So if you need a mid layer or outer layer for high activity (read: sweaty) pick this up.

Warm, soft, and comfortable–fleece just doesn’t get any better than this. The Monkey Man™ Grid II Hooded Jacket boasts Polartec® High Loft™ fleece throughout the body and a flat face stretch fleece on the side panels and hood. This 100% polyester fabric offers outstanding warmth, comfort, and breathability, but does it without adding bulk. Extremely adaptable, the jacket makes a great, insulating mid-layer.
