We took the 72-Hour Hoodie’s signature merino and reinforced it with Spectra®, a fiber 15x stronger than steel used in everything from body armor to performance sailing lines to ultralight backpacks. Sticks and stones may break your bones, but they won’t put a hole in this hoodie—and neither will barbells, rucksacks, or any other type-two fun you throw at it. You still get all the merino magic—moisture-wicking, temperature-regulating, odor-resistant—in a super-soft feel that’s never itchy. That allows you to wash less, wear longer, and simplify your closet and your luggage. This bad boy is strong as steel, light as a feather, and ready when you are.
