Are your clothes really made of bamboo?

At Rumpy, we're bamboo believers. Our garments are crafted from genuine bamboo fabric harvested ethically. It grows faster than a teenager and needs less water than a cactus. Check out each product page for the full scoop on composition.

What's the difference between Uber and Long AF undershirts?

Great question! Our undershirts come in two flavors:

  • Uber: The regular rockstar. It's a smidge longer than your average undershirt, perfect for keeping your midriff under wraps.
  • Long AF: The skyscraper special. It's 2 inches longer than the Uber, ideal for our friends over 6 feet tall who are tired of constant tuck-ins.

Not sure which to choose? Our size guide is your new best friend.

How do I wash my bamboo clothing?

Treat your Rumpy gear right, and it'll return the favor. Here's the down-low:

  1. Wash in cold water on a gentle cycle with similar colors
  2. Skip the bleach and fabric softeners (your Rumpy doesn't need that fake stuff)
  3. Line dry for best results, or tumble dry on low if you're in a rush

Follow these steps, and your bamboo buddies will stick around longer than that jar of pickles in the back of your fridge.

What's your return policy?

We want you to love your Rumpy as much as we do. If it's not love at first wear, you've got 30 days to return unworn, tag-attached items for a full refund. It's easier than returning your ex's stuff! Check out our Returns & Refunds page for all the nitty-gritty details.
