100% Bamboo Viscose
The moment you put them on, you'll understand why cotton was always the wrong answer.
Not scratchy. Not clingy. No waistband cutting in after lunch. You just forget you're wearing anything - which is exactly the point.
Look good. Feel better. Think about underwear less. That's the whole pitch.

★★★★★Everyday wear
“I was skeptical. My wife bought them for me. Now I buy them for myself. Already on my third 6-pack order. My entire drawer is TBo now.”
★★★★★Active / outdoors
“First pair I put on, I immediately ordered the 12-pack. I work construction and these stay dry and comfortable all day. Nothing else comes close.”
★★★★★Durability
“Bought the 6-pack six months ago. Still look brand new after weekly washes. The black hasn't faded at all. Easily the best underwear I've owned.”
★★★★★Travel
“I travel 3 weeks a month. These pack flat, dry fast, and never smell. I brought 6 pairs on a two-week Europe trip and never needed more.”
★★★★★Hot climate
“Wore these through Texas summer. No swamp situation, no chafing, no adjusting. If you live somewhere hot, just stop thinking and buy the 12-pack.”
★★★★★Gym / fitness
“My gym underwear used to be soaked after 20 minutes. These wick everything away. I squat, deadlift, run - zero bunching, zero discomfort.”

Frequently Asked Questions
How does the bundle system work?
Each bundle is a multiple of the TBo 3-Pack Black Trunks. The 3-pack is 1 unit added to your cart, the 6-pack sends 2 units, and the 12-pack sends 4. Pick your size once, check out once, get everything in one shipment.
What size should I order?
Our trunks are athletic-cut. If you are between sizes, go up. Reference guide: S fits 28-30in waist, M fits 32-34in, L fits 36-38in, XL fits 40-42in, 2XL fits 44-46in.
Will the black color fade after washing?
No. High-grade dye that holds wash after wash. Cold wash, hang dry. The only thing fading is your relationship with your old underwear.
Is bamboo actually eco-friendly?
Yes. Bamboo grows without pesticides, needs 30% less water than cotton, and regenerates fast. TBo uses a closed-loop production process to minimise water waste.
Do you offer size exchanges?
Yes. Our 30-day guarantee covers size exchanges. Contact support with your order number and we will sort it out. No drama.
Why should I buy more than 3?
You wear underwear every day. Most guys own 7-10 pairs. The bigger the bundle, the lower the per-pair price - the 12-pack drops to $14.99/pair versus $26 for a single. Replace your entire drawer in one order and stop thinking about underwear shopping for years.
Your Drawer Won't Fix Itself.
Pick your pack. Pick your size. Upgrade everything below the belt.
