What's in for beta-backers?

What's in for beta-backers?

You’ll love the boxstays!

But we’ll be honest, we need your help at this stage.

We love the prototypes of Boxstays we’ve created, and we feel somewhere that they can be enjoyed by other gentlemen that are looking for better shirt stay solutions.

The beta-release is our way to look for these gentlemen. And our beta-release offer is the cut price for those who dare to be the first to try a new idea.

That is why we have limited this special offer to 50 units.

But because you’re sharing the journey with us, here’s what comes in the beta-release packaging:


The beta-test Boxstay.

The Boxstays as we like it at Louis & James… and the only boxstays in the world for several months to come.

Produced in limited version by experienced craftsmen in underwears.

40% Discount.

After completion of the Kickstarter campaign, a 40% discount on our professional range of boxstays which includes 2 stays and 5 boxer briefs (i.e. about $100 for an estimated selling price of $169).

You save about 69 euros on the estimated prices.

The beta-release Boxstay pays for itself at the end.

A product tailored to your taste.

Your personal feedback and preferences will be carefully analyzed by our team and, when possible or essential, will be included in the release version, for a product tailored to your taste.

Your decisions will affect all the gentlemen who will put on the Boxstays!

Remember that with great power comes great responsibility!

*Anthracite will be the only color available for the beta release.

Brittany and Bordeaux will be available on the next step.

Very few units will be produced for the beta-release. Therefore, we will not be able to provide all the different sizes of the Boxstays.

So we will only offer to order and produce the two most requested sizes for the beta-release.

Which size are you?

The Boxstay is a fit-dependent apparel. Your comfort is strongly linked to the choice of the right size. So we made this short guide to help you find the best one.

The size of the Boxstay is based first on the size of your waistband, taken from you with your belly completely relaxed, and NOT from the size of one of your underwear as the latter does not take into account the stretching of the elastic.

On the pictures, our model is 5’11 tall (1,82m), and although he appears thin, he has the 30-year-old bod, with a waist circumference of 93 centimeters.

He is wearing a L-sized Boxstay because of his bod. He can sometimes wear a M-sized undergarment, but it will feel tight. He wears trousers sized 34 US/UK comfortably or 33 US/UK when he stubbornly insists he’s thinner and if he tucks his belly in.

Beta-release delivery.

For beta testing, we ship to Europe with a $3 shipping fee and to US, Canada, Australia and Asia with a $6 shipping fee.

The list of European countries where we ship to can be found here.

Our normal delivery conditions will again apply once the Boxstays are fully released and our delivery system is well established, i.e. free of delivery fees to the US and from $2 to the other countries.

Beta-release return.

Although this is a beta release, we refund any boxstay that is too small to be worn. You will be refunded for the product and the shipping fee (with the exception of return costs) as soon as we get the parcel back.

The Next Big Step : Kickstarter campaign!


Nope. This is the lastest prototype we sewed ourselves with our (rather limited) sewing skills. The version you will receive will be a premium one, manufactured by a company specialized in men’s underwear, which will bring its experience and knowledge in the product.

The product will be basically the same, but more elegant, with a far better finish.

We will post photos and videos of that version when we receive their prototype.

We fully understand the question! In fact, Louis started this journey with a £2 shirt stay (he was in England at the time). He never wore it because the quality was terrible and it was unwearable. But we totally encourage you to try cheaper shirt stays if you’re starting. It allows you to see if shirt stays are something for you in general, and what you like and dislike. We’ve even written a few guides, which you’ll find here.

And if you love the idea of shirt stays, but you are not satisfied with the $5 or the $20 models on Amazon anymore and you’re craving for something entirely different, the Boxstays will be waiting for you 😉

The beta version of the Boxstay is the perfect Boxstay as we dreamed it at Louis & James. It has everything we wanted as users. But it can always be improved. So part of the reason why we decided to release a beta version was that other users, with their own experience, may have great ideas that are worth incorporating. And we want to make the Boxstays the best possible experience for everyone.

But it is true that at $39 for the beta release, the Boxstay is challenging premium shirt stays.

And yet, they are cheaper than most branded shirt stays.

Compared to regular shirt stays which are mainly a pair of elastics, the Boxstays are composed of 2 pieces: the boxer briefs and the stays (the elastic component).

Each of these elements is of premium quality, crafted following strict standards. And most importantly, each separate element even requires more handwork than their regular equivalent.

The Boxstays’ boxer briefs require 4 more premium elastic bands than a regular undergarment, without mentioning a specific manufacturing procedure.

The Boxstays’ stays are just shorter than regular shirt stays but it is composed of several unique parts that regular shirt stays simply don’t have.

That’s like $20 for a more elaborate and premium boxer briefs and $20 for more elaborate and premium stays.

Your participation during any phase of this project will be greatly appreciated. But the beta release is not a bad or a risky deal either. It is actually one of the best deal we will probably offer:

The beta release is probably the cheapest edition of the Boxstays since we take almost no personal profit or payment from it. The Boxstays will be produced in limited quantities which increase the price of its manufacture. And the potential margin on these sales will be used to finance the next steps. This is one of these case where you pay for a product and not a brand.

The Kickstarter campaign and further public release will still take several months before launch and even longer before completion. The Boxstays of the beta release will be the only Boxstays in the world for several months to come.

Although we didn’t directly mention it, we mainly see the beta release as an offer for users who wear or plan to wear shirt stays several times a week, as part of their work or activity.  That is why we completed our offer with a 40% discount on the (future) professional range of Boxstays (2 stays and 5 boxer briefs) upon the public release. We want to make sure that our beta backers are reimbursed for the price of the beta version at the time of the public release.

Thank you ! Since we are users first, we try to provide the best deal for our (future) customers. If you’re tempted for the beta release, it is just below.
