As a reader discovered, Massif Collection takes 40% off sitewide during its Winter Sale. (Prices are as marked.) That's the best percent-off sale we've seen from Massif Collection, which offers "clothing for spies." Pants start at $87, while sweaters start at $135, among other discounts. Shipping adds around $6. Deal ends February 15.
A best bet is the Massif Collection Men's P-007 Off Duty Pants in Black Tech Wool (pictured) for $150 with $6.49 for shipping. That's $100 off and the lowest total price we could find for this style. It comes in waist sizes 30 to 38 in either 32 or 34 inseam.
