HEMPZOO Trek pants are designed in California with lightweight comfort and a natural body armor in mind. The performance slim fit design is great for your every day hustle and grind. The tapered legs and a knee to knee crouch gusset is designed to give you maximum comfort. They run slim so we recommend sizing up. They keep you cool in the summer and warm in the winter. The durable, strong and porous micro hemp fiber structure allows natural breathability and absorbency to quickly wick away moisture from your skin and airflow dries the remainder to help balance body moisture. HZ Trek pants wear in not out! The more you wash and wear them the softer they become for you to enjoy for years to come. Naturally good for you and our planet.
