Underwear is one of those everyday essentials we don’t think much about—until we find a pair that completely changes the game. Enter ON THAT ASS, a bold and cheeky brand that’s flipping the script on men’s boxers with a unique subscription model that delivers a fresh new design to your letterbox every month.
It’s quirky, fun, and definitely eye-catching. But is it actually worth it? I decided to sign up, test the quality, see what the fuss is all about, and find out if ON THAT ASS is just a clever name—or the real deal.
If you’re in the UK and curious about upgrading your underwear drawer, this honest, detailed review is for you.
What is ON THAT ASS?
ON THAT ASS is a subscription-based boxer shorts brand originally launched in the Netherlands, and now gaining serious momentum in other countries—including India and the UK. They offer a monthly membership where subscribers receive one exclusive, high-quality pair of boxer shorts each month, delivered right to their doorstep.
What makes it unique?
- Surprise designs: You don’t pick the boxers; each month brings a brand-new, limited edition design.
- Free first pair: You get to choose your first pair for free when you sign up.
- Flexible subscription: It’s a rolling monthly subscription with the option to pause or cancel anytime.
It’s underwear—but with a twist. And for those who enjoy style, comfort, and a bit of surprise, it promises to be more exciting than your usual multi-pack from Primark or M&S.
Signing Up: The ON THAT ASS Experience
The sign-up process is super simple, and that’s something I appreciated right away.
- Go to the website (UK version is slick and easy to navigate)
- Pick your first pair from a curated selection of their greatest hits
- Create your account
- Enter your address and payment info
- Receive your free pair within a few days
There’s no complicated checkout, and the fact that the first pair is completely free (with no hidden shipping costs in the UK) makes it pretty risk-free to try.
The current price as of writing this review is around £11.99/month after the free trial—comparable to or slightly more than premium high street options, but with better presentation and exclusivity.
The Free Pair: First Impressions
Once my first pair landed, I was honestly impressed.
Packaging
- Arrives in a sleek, branded envelope
- No excess plastic, eco-friendly vibes
- Minimal, clean design that still feels fun
The Boxers Themselves
I chose a pair called “Shark Attack” from their featured designs, and it definitely stood out. Bright, bold, and not something you’d typically find in stores. But it wasn’t tacky or novelty-level loud—it hit that sweet spot between playful and stylish.
Material
- Made from 95% polyester and 5% elastane
- Soft to the touch, almost like premium sportswear
- Lightweight but not flimsy
- Good stretch, stays snug without being restrictive
Fit & Comfort
- Mid-rise, solid waistband with branding
- Contoured pouch for support (and it actually works)
- No riding up throughout the day
- Breathable enough for hot weather or workouts
I wore them for an entire day—working from home, quick errands, lounging on the sofa. Zero discomfort, no bunching or sweating. Genuinely surprised by how premium they felt.
Monthly Surprises: The Subscription Experience
After my free pair, I let the subscription continue for three months to really get a feel for the experience.
Here’s what stood out:
1. The Excitement of Not Knowing
Each month’s design is a surprise, which adds a small thrill to the otherwise dull world of underwear shopping. Some designs are bold, some more neutral. But they all have character, and you won’t find them elsewhere.
2. Reliable Delivery
- Always arrived around the same time each month
- No customs fees or delivery issues in the UK
- Discreet packaging (so no awkward post office pickups!)
3. Design Variety
Here are the designs I received:
- “Thunderstorm” – A moody blue/purple abstract print
- “Cactus Club” – Tropical vibes with palm trees and a desert green tone
- “Crimson Fade” – More minimal, deep red with a subtle pattern
Each pair felt like it had thought behind it—not just random patterns thrown onto fabric. And again, they all fit perfectly, wash well, and feel like they’ll last a while.
Build Quality & Durability
One of my biggest worries was longevity. I’ve tried some “premium” underwear brands before that looked great for two wears and then lost their shape or softness.
After multiple washes (machine wash, 30 degrees, air dry), all my ON THAT ASS pairs:
- Held their elasticity—waistbands still snug
- Didn’t fade or bleed colours
- No pilling or loose threads
- Retained shape and softness
These boxers are built to last. I wouldn’t recommend tumble drying though—best to air dry to preserve the stretch and colour.
Who is ON THAT ASS For?
Honestly, this service isn’t for everyone—but it has a clear audience:
Ideal For:
- Young professionals or students who like a bit of flair
- Gym-goers or active folks needing comfort + support
- Style-conscious guys who appreciate detail (even in underwear)
- People who like fun surprises every month
Maybe Not For:
- Ultra-budget shoppers (though the quality justifies the price)
- Those who prefer plain, unbranded basics
- People who want to choose exactly what they wear daily
Price & Value
At £11.99/month, ON THAT ASS sits in the “premium but not luxury” category. Here’s how it compares:
| Brand | Price (approx) | Monthly Designs | Surprise Element | Free First Pair |
|---|---|---|---|---|
| ON THAT ASS | £11.99 | Yes | Yes | Yes |
| Calvin Klein | £20–£30/pair | No | No | No |
| M&S | £10–15/pair | No | No | No |
| Oddballs | £10–15/pair | Yes | Yes (limited) | No |
When you factor in quality, design uniqueness, comfort, and the delivery convenience, I’d say the value is excellent—especially if you’re someone who likes to treat yourself to small joys without breaking the bank.
