The Smartwool PhD HyFi Full Zip Hoody is a perfect mid layer piece for early morning commutes. The fit allows for full movement on the bike, and its breathability is key in keeping you dry when exerting yourself. The hood is a full coverage affair, leaving no part of your neck exposed to the elements. It is also quite slim, allowing your helmet to easily fit over it. There are thumb holes, a zip chest pocket, and zip hand pockets. It is a great stand alone piece when the temperatures are mild, but perfect for layering when the temperatures drop. I’m looking forward to using this piece when I next go skiing. Layered with the Smartwool NTS Micro 150 Crew and a ski jacket, this should make for a perfect combination. On the bike, it has already won me over.
