Men's trunk underwear: 5 things to know before you buy

Curious about the trunk? If you don’t already know this style, it’s time to get acquainted. This relative newcomer to the world of men’s skivvies combines some of the best attributes of other underwear styles to create a well-balanced, versatile, and on-trend option.

Given those strengths, it’s not surprising that this men’s trunk underwear cut is getting very popular, very quickly. But it’s also under appreciated - including by many guys who wear trunks all the time. How is that possible? Well, lots of men don’t even realize that their go-to cut is in fact the trunk. 

There’s a lot of confusion around terminology here, so let’s get clear on what we’re talking about before we dive deeper.

What makes a trunk?

The trunk is basically a boxer brief with a shorter inseam. Like the men’s boxer brief, the trunk combines the form-fitting support of a brief with the fuller body coverage of a boxer. But while the boxer brief traditionally extends all the way down the thigh, the trunk inseam is significantly shorter. 

Plenty of men who wear trunks just call them boxer briefs. If you happened to grow up in the era of boxers vs. briefs, then this makes intuitive sense - anything that combines the form-fitting nature of the brief with the leg coverage of a boxer is a boxer brief, right? 

Again, not quite. If you want to get technical about it - at Tani we tend to do that about all things underwear - the shorter leg length is really its own innovation. So this cut has earned its distinct name: the trunk. 

When you think of technological achievement, you’re probably not thinking of men’s underwear.   However, time for a re-think. Our FreeForm Contour Trunk is the newest men's underwear design and a first in men’s underwear.

There’s no hem or binding on the leg and yet, this remarkable underwear won’t bunch, crimp or ride up. FreeForm lies perfectly flat, making a seamless, supple connection between the fabric and your skin. 

Our newest men's underwear design is made from premium soft, naturally wicking fabric that keeps you dry making them perfect for everyday comfort. Slight stretch allows for contouring without constriction. No leg binding enhances comfort around the leg. Designed with a super soft Jacquard waist band.

5 things to know before you buy

If your current go-to underwear cut is the boxer brief, the shorter inseam length of the trunk may seem like a minor difference. But the truth is the difference in thigh coverage makes the trunk a distinct option with its own special place in your underwear drawer - and life. 

Whatever underwear cut is your go-to choice right now, if you’re interested in trying the trunk, here are the five things you need to know before buying.

  1. Trunks keep you cool

You adjust the rest of your wardrobe to fit the season. If your underwear drawer doesn’t offer its own flexibility for maximum comfort in different weather conditions, it might be time to expand your collection. With their shorter legs, trunks are obviously a breezier option than boxer briefs. 

So whether you live in a warmer climate, need some options better tailored to summer heat, or you just tend to overheat easily, trunks will keep you cool and dry in any situation.

  1. Trunks are trendy

Trunks can keep you cool in more ways than one. This cut is a youthful and of-the-moment option, without being overly flashy. Trunks are a great choice for men of all ages to demonstrate they’re up-to-date on current fashion trends. A trunk in a bold, masculine print or a classic color like navy or black balances trend with tradition perfectly, for a look that says you’re in-the-know without getting too showy.

  1. Trunks work well for moderate exercise

With their form-fitting shape, trunks offer as much support as a brief plus a bit of leg coverage to boot. This makes them suitable for moderate exercise. For an intense workout, many men prefer full-length leg coverage for greater protection against chafing and irritation. But if you’re the sort of guy who bikes to the office and always opts to take the stairs, trunks might be the perfect choice for your active everyday lifestyle. 

  1. Trunks can make you look taller

Exposing more of your leg creates a longer, uninterrupted vertical line that can make you look taller. So whatever your current height, if you’d like to emphasize that visual dimension, know that the shorter the inseam the more pronounced the effect will be. Trunks are a great choice if briefs aren’t your thing.

  1. Great for dates

Trunks are a great choice for date nights when you want to feel confident and look well-styled - but not like you’re trying too hard, either. Trunks let you show off a little thigh without being too attention-grabbing or highly exposed. This underwear shape is a perfect blend of what you’re likely aiming for in your whole date-night outfit: bold, assertive, and in touch.

The bottom line

There are plenty of reasons to love this cut. Overall, trunks are a great everyday option because of the way they balance practicality and style. They provide all the support you need for an active lifestyle, a smooth look under fitted pants, and moderate thigh coverage that works well for most seasons and situations.
