Work doesn't stop in the warm-weather months just because it's hot. That said, you can feel better about the dog-day swelters when you pull on a pair of Costello Tech Pants in the morning. Built with an ultra-light 5oz fabric, the Costello won't weigh you down in triple-digit temps. While they're plenty comfortable, these pants are sneaky tough. The fabric has a durable, mini ripstop nylon construction and is infused with four-way stretch, making it tough yet flexible.

• Four-way stretch for flexibility
• Mini ripstop nylon build is tough despite it's lightweight feel
