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.

Jason Costello is a veteran landscape curber with over 20 years of experience under his belt. He’s based out of the High Desert region of Southern California which is no stranger to high heat more often than not. We collaborated on the Costello Pant not just for him, but for anyone who’s working outside when it’s hotter than hell. The lightweight comfort is great for brutal summer days, and the rugged construction is ideal for the daily grind. - Eric Girouard, Founder + CEO
