About OnThatAss

OnThatAss is an exciting and fast-growing men’s boxer shorts subscription service that delivers a fresh, exclusive design to your door every month. The OnThatAss UK platform has revolutionised the way men buy underwear, transforming it into a fun and convenient experience. As the leading monthly underwear club, OnThatAss is renowned for its bold and unique design boxer shorts that are guaranteed to be a conversation starter. The brand is focused on providing comfortable and stylish boxers made from high-quality materials, with a perfect fit guarantee. For new members, the OnThatAss free trial is an unmissable opportunity, with their famous introductory offer allowing you to get your first pair free.

Why Join OnThatAss?

OnThatAss has become a hugely popular subscription for several compelling reasons:

  • A New, Exclusive Design Every Month: A key feature is the surprise and exclusivity. Every month, members receive a brand-new design that is never repeated, ensuring their collection is always fresh and unique.
  • Get Your First Pair Completely Free: The brand’s legendary introductory offer allows new members to try their first pair of high-quality boxer shorts for free to experience the comfort and quality for themselves.
  • High-Quality and Comfortable: The boxers are made from a premium blend of cotton and elastane with a soft waistband, designed for ultimate comfort and a perfect fit.
  • Ultimate Convenience: The subscription service takes all the hassle out of buying underwear. A new pair is delivered automatically through the letterbox each month.
  • A Flexible, No-Commitment Subscription: Members are in complete control. The monthly membership can be easily cancelled at any time through a user’s online account.

How the OnThatAss Subscription Works

Getting started with this unique monthly underwear club is a simple process:

  1. Sign Up and Choose Your Style: Visit the website, choose a preferred style (Boxers with a normal leg length or a longer leg length), and select your size.
  2. Get Your First Pair Free: Register your details to claim the free trial. The first pair of boxers will be sent out completely free of charge.
  3. Receive a New Design Monthly: If you love the boxers and continue your subscription, a new, surprise design will be dispatched each month for a set monthly fee.
  4. Manage Your Account Online: Members can easily manage all aspects of their subscription, including pausing a month or cancelling, through their online account.

Benefits of an OnThatAss Subscription

Joining the OnThatAss club offers many significant advantages:

  • Effortlessly Refresh Your Underwear Drawer: The service provides a simple and convenient way to ensure you always have a supply of fresh, high-quality, and stylish boxer shorts.
  • Express Your Personality: The bold, colourful, and often humorous limited-edition designs are a fun way to express individual style.
  • The Perfect, Low-Risk Trial: The ability to get your first pair free makes it a completely risk-free way to test the product’s quality and fit.
  • Never Wear a Boring Pair of Boxers Again: Say goodbye to plain, multipack underwear and hello to a more exciting daily essential.

Things to Consider When Subscribing

To get the most out of the service, potential members should keep a few points in mind:

  • The Trial is a Subscription: The fantastic free trial offer automatically signs a user up for a rolling monthly subscription. It’s important to be aware of the date the first full-price pair will be dispatched, although this can be easily cancelled.
  • The Designs are a Surprise: Part of the fun is the surprise element. Members do not get to choose the design they receive each month.
  • Subscription for Men’s Boxers Only: The core subscription service is exclusively for men’s boxer shorts.

Tips for a Great OnThatAss Experience

Members can get the most out of their subscription with these tips:

  • Take Full Advantage of the Free Trial: This is by far the best way to try the service at zero cost.
  • Use the “Perfect Fit Guarantee”: If the first pair isn’t the right size, members can contact customer service to get a different size sent out.
  • Refer a Friend: Keep an eye out for their refer-a-friend scheme, which can offer rewards for both the existing and new member.
  • Manage Your Account Actively: Use the flexible online account to pause a delivery if you’re going on holiday or have too many pairs.

As a major European subscription service, OnThatAss provides customer support through their official UK website, with a detailed FAQ section and contact information. They have clear and transparent policies regarding their flexible subscription model, which is easy to manage online, providing a reliable and customer-friendly service.
