Nike 550 Fill Vest
Here's what other sites are saying:
Get the everlasting warmth of a puffy without the puffed-up bulk when you wear the Nike Men's 550 Fill Vest as a midlayer for chilly ski sessions. Nike stuffed this vest with warm down insulation to add a bit of warmth for times when your core just needs that extra bit your shell just doesn't provide. The mock neck style of this vest lets you turtle things up when chairlift rides are threatening to freeze your toes and other sensitive parts.
