ON THAT ASS is a membership-based underwear brand that delivers exclusive, high-quality boxer shorts (and socks/women's sets) directly to your mailbox every month. The brand is built on a "surprise" model where you don't know the design until it arrives, ensuring your drawer is never boring.
As of late February 2026, the following offers are available to new members:
14-Day Free Trial: Choose your first pair of Originals (Print) or One (Solid) boxers completely free.
1+1 Bonus Promotion: A current limited-time deal where you receive two free pairs (one you choose, one mystery pair) upon signing up for the 14-day trial.
Monthly Shopping Credit: Active members receive €10 (approx. £8.50) in monthly shopping credit to spend in the Loyalty Shop on extra items.
Sock Membership Discount: If you have an active boxer membership, the price of the Socks subscription drops from €8.99 to €5.99/month.
Memberships are flexible and can be paused or canceled monthly after the initial trial.
Registration: Sign up and choose your first free design. A €0.02 verification fee is required to link your payment method.
Trial Period: Your 14-day "reflection period" begins once you sign up. The first pair usually arrives within 4 working days.
Cancellation Policy: You can cancel for free within the first 6 days of your trial. After the 14 days, you transition to a paid monthly subscription.
Monthly Delivery: Payments are debited around the 23rd of each month. Your surprise delivery arrives between the 17th and 23rd of the following month.
The 20th Threshold: Because you pay a month in advance, the 20th of the month is usually the cutoff for the following month's delivery/cancellation.
Mystery Pair: If you signed up under the 1+1 deal, you receive the second "Mystery" pair only after your 14-day trial ends and your first paid month begins.
Account Limits: You can only create one "Men" account per unique bank/IBAN to prevent misuse of the free trial offers.
User Tip: Many recent reviews (Feb 2026) highlight that while the fit and quality are highly rated, the subscription can be tricky to cancel if you miss the specific window. Always check your account dashboard exactly 5 days after signing up if you don't intend to stay a paid member.
In a world of endless subscriptions, ON THAT ASS stands out because it provides genuine value to a part of your life you usually ignore. It’s the perfect blend of utility and excitement. Whether you’re signing up for the 14-day free trial to snag that first pair of Originals or you're looking to upgrade to a full wardrobe of One solids, you’re making a choice to prioritize yourself.
