The Costello Tech Pant Pack is here to ensure you’re getting a seriously solid value when you stock up on pants. 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. And since you’re investing in more than one, we want to make sure you got something on the house with a bonus pant in every pack.
