Some time last spring I found myself explaining leg opening construction to a man at a christening. He had asked what I did with my weekends. I had a window of perhaps four seconds in which to say something normal, and instead I said the words "bound edge".

He was very good about it. He nodded the way you nod at a man describing a dream, then moved sideways along the buffet with the practised motion of someone who has been cornered before, and I stood there holding a paper plate, understanding for the first time that I had become a person with a cause.

This is a campaign plan for men in that position. It assumes you have made a change you are pleased with, that you would like the people you like to have it too, and that you would also like them to keep inviting you to things. Those objectives are compatible. They are just not compatible with any method you will instinctively reach for first.

I know exactly how ridiculous this is. We are talking about a fabric object worn under trousers. I am going to lay out a persuasion strategy anyway, because everything I learned trying to be less annoying about this turns out to be a set of rules about how anyone changes any habit at all.

Phase zero: an honest assessment of the objective

The stated aim is that your friend tries a brief. The actual aim, the one you have not admitted, is that your friend agrees with you.

These are different operations and only one is achievable. You can put a garment within a man's reach at a moment when he wants one. You cannot install a preference. Any plan built on the second objective will fail and will cost you something on the way out, because a man being persuaded can feel the difference between someone solving his problem and someone winning a point, and he feels it about two sentences before you do.

So the first instruction is a demotion. You are not campaigning. You are running a very small logistics operation, and the goal is that when the moment arrives, the option is already nearby.

Why the direct approach fails, in detail

The direct approach is to tell a man his underwear is wrong. Nobody has ever survived this.

The reason is not that he disagrees with the argument. He has not heard the argument; he stopped at the premise. What you have actually said is that a decision he made at fifteen and has not revisited since was a bad decision, which lands as a comment on his judgment rather than his drawer. He will now defend the boxer short, a garment he has never had a single thought about, with real ferocity, because you made it a question of who is right. What comes out of him at that point is not an argument but a set of inherited lines, and it is the same short list every time Things Men Say About Briefs, Ranked by How Wrong They Are.

There is a second failure underneath the first. Underwear is one of the very few things a man chooses purely for himself, unobserved, on no advice from anyone. That is what makes the switch feel good when he makes it himself, and an intrusion when someone else proposes it. You are not offering a product recommendation. From where he is sitting, you are offering to redecorate a room he did not show you.

Nobody has ever changed their mind at a barbecue

Every man who has taken a position in public has taken it in front of witnesses, and the witnesses are the problem.

At a barbecue, in a pub, in a group chat, in any setting where more than two men can hear the exchange, the subject stops being underwear within about fifteen seconds and becomes a small contest with an audience. He is no longer weighing a comfort claim. He is managing his standing among people he sees every week. Even if you are entirely right, the cost of publicly agreeing with you is higher than the benefit of being comfortable, and he will pay the cheaper price. He would be irrational not to.

Hence one of the few hard rules here. No conversions in groups. Ever.

If the subject comes up in a group, and it will, your job is to be boring about it. Say something short and unbothered and let the topic die; there is a whole piece on handling that moment in So Someone Asked Why You Wear Briefs. Being unbothered in public is worth more than any argument, because what actually persuades men is watching someone be quietly, obviously fine.

The one moment a man is receptive

There is a window. It is narrow, it opens without warning, and it is always attached to a problem he has just described out loud. Three reliable versions:

He is going somewhere hot. A week in Greece, a work trip to Singapore, a wedding in August. He is already packing, already thinking about bulk and drying time, and halfway to admitting that four pairs of heavy cotton boxers is a poor use of a carry on. This is the softest opening there is, because the recommendation is about the trip rather than him. Travel Light: The One-Bag Case for Briefs exists for this conversation, and A Summer in Italy: What to Pack (Spoiler: Slips) is the version to send if local norms will do half your work.

He has taken up a sport. Running, cycling, swimming, five a side, a gym membership in January. New activity means new kit, and new kit means a man briefly in a buying frame of mind with no established preferences to defend. He has no position on what to wear under cycling shorts because he has never worn cycling shorts. Answer what he asks, nothing more, and point him at Right Support, Right Sport: What to Wear for What You Do.

He has just complained about a fit problem. This is the highest value moment in the campaign and most men waste it by getting excited. His boxer briefs ride up. The seam chafes on long days. He chafes on the inner thigh every summer without fail. He is not asking for a philosophy. He is describing a mechanical failure, and the correct response is a mechanical answer, which might be a brief and might equally be a longer leg in a better fabric. If the problem is thigh chafing, Underwear for Big Thighs: The Chafing Problem Solved is more useful to him than any opinion of yours.

Note what all three have in common. He opened the subject. You did not.

Rules of engagement

Given a window, four rules govern what you do inside it.

Answer the question asked. He asked what to pack. Tell him what to pack. Do not then explain the continental fit tradition, the panel count and why the English speaking world got embarrassed. Every sentence past the answer reduces the chance he acts on it, and this is the rule I break most.

Be specific and be brief about it. "Two pairs of these, they dry overnight in a hotel sink" is a recommendation. "You should really try briefs" is a lifestyle proposal. Only one can be acted on this evening.

Never mention the price you paid. It sounds either like an instruction to spend money he had not planned to spend, or like an affectation. If cost comes up, the honest answer is that this is a category where the cheap option is frequently the right one, which is the subject of The Best Cheap Underwear That Is Not a False Economy.

Do not follow up. Not once. If he tries them and likes them he will tell you, usually months later and as though he thought of it himself, which is the desirable outcome. If he did not get on with them, asking turns a neutral non event into an awkward one, and the subject now has a small charge on it for ever.

The gift that works, and the gift that is a hostage situation

Giving a man underwear is a manoeuvre with a very small margin for error.

The gift that works is small, incidental, attached to something else and in his size, which means you already knew his size for an innocent reason and did not conduct research. One pair, not a set. Ideally handed over in the context of an event: he is going away, he has a race, it is the thing you always bring back from that shop. A single merino travel brief tucked into a card requires nothing from him. He can wear it, lose it or leave it in a drawer, and you will never know, which is the point.

The gift that is a hostage situation is the multipack. Five pairs of anything is not a present; it is an expectation with a ribbon on it. He now has a drawer full of an obligation, and every time he opens it he is being asked a question by a man who is not in the room. On buying anything in fives, Against the Multipack has more to say.

The other gift that fails is the one really about you: something conspicuous, chosen because it would be funny, given to be reacted to. Christmas has its own forgiving rules. Outside that fortnight, if the gift needs an audience, it is not a gift.

For a man who has genuinely asked, a plain cotton rib brief in navy or grey from a serious maker is close to unlosable, and the reasoning is in Five Briefs Worth the Money.

The conscientious objector

Some men will not convert, and the reasons are mostly good ones.

Some genuinely prefer the alternative. The loose boxer is a real garment with real virtues in hot weather and around the house, and pretending otherwise damages your credibility on everything else you have said. In Praise of the Loose Boxer is on this site for a reason.

Some are not interested in clothing at any level and never will be. A man who has worn the same six pairs for a decade and thinks about it never is not a project; he is a person with different priorities, most of them probably more sensible than yours.

And some will not do it because you suggested it, and would have done it happily if they had come across it themselves. This is the hardest category to accept and the largest one. Let them alone. The conversion rate on leaving people alone is not zero, which is more than can be said for the alternative.

What this is actually about

Strip out the subject matter and what is left is the standard shape of how habits change, whether the habit is a garment, a running route or how someone eats.

Nobody adopts anything because they lost an argument. People adopt things when a problem they already have meets a solution already within reach, at a moment when nobody is watching and nothing is being asked of them. The friction that matters is almost never persuasion. It is the boring stuff: not knowing which to buy, not wanting to stand in a shop, not wanting to have made a decision they would have to explain. Remove those and you have done more than any speech at a barbecue could.

Which means the campaign, properly run, is four things. Be boringly fine. Wait for a man to describe a problem. Answer exactly what he asked. Then say nothing else, possibly for years.

The admission

I am aware this is an absurd amount of thought to give to whether other men enjoy their underwear.

There is no cause here and nobody is suffering. If every friend I have goes to his grave in a supermarket five pack he will not have missed anything that matters. The stakes are, generously, minor comfort.

But there is a version I do stand over. Most men are walking around in the default they were handed at fifteen, in a category nobody ever helped them think about, and a few of them are quietly uncomfortable every day and have decided that is simply what bodies feel like. That is a small, fixable, entirely unnecessary thing. If you can be the reason one man finds that out, without ever once making him feel got at, that seems a reasonable use of a Tuesday.

So yes, it is faintly ridiculous, and I intend to go on doing it. Quietly, in the correct window, one pair at a time, and never at a christening again. If he does try it, the two week bedding in period is real and is mapped out in Making the Switch: The 14-Day Brief Plan, which is a better thing to send than anything you might say.

Others have run the same campaign with more patience and better results, including one man who has been working on a single colleague for two years and files progress reports like a field commander. Their dispatches are in The Postbag: How I Converted My Mates.

Questions people ask

How do you convince someone to try a different type of underwear?

You largely do not convince them. What works is waiting until they mention a relevant problem, such as packing for a hot holiday, starting a new sport, or complaining about chafing, and then giving one specific, practical answer to the question they actually asked. Direct suggestions that their current choice is wrong produce defensiveness rather than curiosity, because people hear it as a judgment on their taste. Make the option easy to reach, then stop talking about it.

Is it appropriate to give underwear as a gift to a friend?

It can be, if it is small, casual and unconditional. One pair attached to a specific occasion, such as a trip or a race, reads as thoughtful and asks nothing of the recipient. A large multipack reads as an expectation, particularly if the giver has strong views, and something conspicuous given for the reaction is really a gift to yourself. Get the size right from something you already know, and never present it in front of a group.

Why do people get defensive about their underwear choices?

Because underwear is one of the few things chosen entirely for oneself, without advice or observation, usually settled in adolescence and never revisited. A suggestion to change it lands as a comment on personal judgment rather than on a product. In groups the effect is stronger, since agreeing publicly with a criticism carries a social cost that outweighs the practical benefit. These conversations go better one to one, and better still when the other person raises the topic.

How long does it take to get used to wearing briefs?

Most men report that it takes around two weeks of consistent wear. The first few days can feel unfamiliar simply because the sensation is different, not because anything is wrong, and the common mistake is judging the switch after a single day. Fit matters more than adjustment time: if a pair rides up, digs in or rolls at the leg, that is a sizing or construction fault rather than something to acclimatise to, and the answer is a different pair.
