ARE YOUR CLOTHES MADE OF BAMBOO?

At Rumpy we specialize in creating garments made from sustainable bamboo fabric. Bamboo is a renewable resource that requires minimal water and no pesticides to grow, making it an eco-friendly choice. Check the composition of each clothing item under the "Fabric" tab on the product page.

UNDERSHIRTS: WHAT IS THE DIFFERENCE BETWEEN UBER AND LONG AF?

Our Undershirts come in two sizes: Uber and Long AF. The Uber is a regular undershirt, only slightly longer than your average men undershirt to stay tucked in all day.

The Long AF is 2 inches longer than the Uber, making it more suitable for men taller than 6'

If you're unsure on which to order, please refer to the size guide.

HOW DO I KNOW WHICH SIZE TO ORDER?

To find the perfect fit for your undershirt, underwear or shorts, we recommend referring to our size chart available on each product page. Our size chart provides accurate measurements for each garment, allowing you to select the size that corresponds to your body measurements. If you're unsure about your size, feel free to reach out to our customer support team, who will be happy to assist you in finding the ideal size for your comfort.

If you ordered the wrong size, we offer a 30-day return policy.
