Bamboo Briefs With a Fly – Guide

Short answer: Bamboo underwear with a fly combines the practical opening at the front with the soft, breathable comfort of bamboo viscose. The fly is a matter of taste, but many men prefer it for practical reasons, and in bamboo you also get dryness and freshness all day. The construction decides whether it can be felt.

Why many choose a fly

The fly is above all practical day to day, and for many it is a habit from the underwear they grew up with. Some models have an open fly, others an overlapping closure that lies flat and cannot be felt. If the fly is a requirement for you, check the description of the individual model in the range of bamboo underwear for men.

The two constructions

The open fly is two pieces of fabric meeting without overlapping. It is the simplest and flattest but can gape slightly in certain positions. The overlapping fly has two layers sitting on top of each other, so there is no opening to see. It is slightly thicker but more discreet under thin trousers.

Bamboo viscose is soft, breathable and dry

Bamboo viscose carries moisture away from the skin and feels cool and soft against the body. That makes the material an obvious choice for underwear, where cotton quickly turns damp and clammy over a working day. The difference shows most clearly at the end of the day rather than in the first hour.

Brands with fly models

Several of our brands make underwear with a fly. Look among others at JBS and Resteröds, both known for classic men's models of good quality. If you are unsure about fit in general, start by measuring your waist rather than going by the trouser size you usually take.

How to read a product description

Look for three things. The fabric composition, where the first figure decides how the item behaves. Whether an open or overlapping fly is stated. And the leg length, if it is a boxer model, because that decides whether the leg rides up. If nothing is said about a fly, the model usually has none.

When the fly can be felt

A noticeable fly comes either from a thick layer of fabric in the overlap or from a seam sitting in an awkward place. If that is a problem for you, choose a model without a fly instead, because there is nothing to gain from keeping a detail you feel all day. The material is the same.

Washing and lifespan

Wash at 30 to 40 degrees and hang them to dry. Bamboo viscose is weaker when wet and therefore tolerates high heat in the dryer poorly. Skip the fabric softener, which leaves a film in the fibres and closes off the moisture transport. Turn the item inside out in the wash so the seams take as little wear as possible.
