Male trunk underwear has earned its reputation as the most versatile cut available by actually being the most versatile cut available. It works for a lean frame and a broader one. It suits a tall bloke and a shorter one. It handles physical work and desk work without needing to be changed between them. I think the reason male trunk underwear works for every body comes down to the proportions of the cut: enough structure to support, enough room to move, and a leg length that stays in place without being excessive.

What I think makes male trunk underwear specifically body-inclusive is the leg length. Longer cuts can be restrictive on broader builds. Shorter cuts can ride up on taller builds. The trunk sits in a position that works across a wide range of proportions without compromising the function of the cut. That middle-ground sizing philosophy is why I recommend the trunk to most blokes regardless of their build, at least as a starting point.

A bloke I know who's a larger build had tried most cuts without finding one that worked properly. Boxers were too loose. Boxer briefs were too warm and the leg length was awkward. Briefs were too minimal. He tried male trunk underwear from Barramundies and said the fit was the best he'd experienced in any cut. The proportions of the trunk suited him in a way the other cuts hadn't. That's the body-inclusive argument in practice.

From my experience, male trunk underwear from Barramundies is the right starting point for any bloke who hasn't found a cut that works. The proportions are right for Australian bodies across the range of sizes and builds. If you've dismissed trunks based on a cheap version that didn't fit, try a quality pair and reconsider. The cut works for most bodies when the construction is right.
