Cloth Weight Explained

An introduction to cloth weight, season and use

From fibre to cloth: materials and tools from the Fox Brothers archive. 

At Fox Brothers, cloth weight is more than a number. It is a defining part of a cloth’s character, shaping the way it drapes, the seasons in which it thrives, and the garments it is most often chosen for. Across our collections, weight offers an initial indication of character and intent, but how a cloth performs is shaped by a combination of yarn, weave, and finish. From lighter worsteds to substantial flannels and tweeds, each weight reflects a balance of purpose, tradition, and use, developed through centuries of clothmaking in Somerset.

Understanding Cloth Weight

Cloth weight influences how a garment feels on the body, how it moves, and how it wears over time.

Lighter weight cloths are often chosen where ease and breathability are desired, particularly in warmer conditions.

Mid-weight cloths sit at the centre of many wardrobes. They balance structure with comfort and are worn regularly across settings and a wide range of climates and seasons.

Heavier cloths bring warmth, substance, and presence. These weights come into their own in cooler conditions, offering texture, drape, and a reassuring sense of permanence.

Fox Brothers express cloth weight in grams per linear metre. This reflects the weight of one metre of cloth, woven to a fixed width, once the cloth has been finished, and is sometimes shown alongside traditional ounce equivalents. Rather than focusing on numbers alone, it is worth considering when and how the cloth will be worn.

While weight is an important reference point, it is not the sole determinant of how a cloth wears. Yarn type, spinning, weave, and finish all play a significant role in how a cloth feels and performs. Two cloths of similar weight may wear very differently, as seen in collections such as Fox Air and Fox City, where differences in yarn and construction result in distinct handle and behaviour. The finished garment also matters: lining, construction, and intended use can all influence how weight is perceived in wear.

Fox Brothers cloth collections by weight

The table below outlines the principal Fox Brothers cloth collections, their typical weights, and the character they bring to tailored garments.

Choosing cloth by season

Lighter weights: warm weather and movement

Lighter cloths are often selected when comfort is paramount and conditions are warmer. They sit lightly on the body and are well suited to garments worn in higher temperatures or milder climates. These weights are commonly chosen for summer suits, lightweight jackets, and tailoring intended for travel or extended wear in warm climates.

Mid weights: year-round versatility

Mid-weight cloths form the backbone of many wardrobes. They perform reliably across much of the year and are valued for their balance of structure and comfort.This bracket is frequently chosen for everyday suits, separates, and tailored trousers that are worn regularly and in varied settings.

The heaviest cloths: flannel and tweed

The heaviest cloths are chosen deliberately. Tweeds and heavy flannels bring depth, warmth, and longevity, and are often associated with cooler climates and more demanding conditions. These cloths are not intended for year-round use, but when conditions call for them, they offer comfort and character that lighter weights cannot.

Choosing cloth by garment

For suits

Cloths between 290g and 430g are most commonly chosen, offering balance, structure, and comfort across much of the year.

For jackets

Heavier weights, including tweeds and sports jacketing, provide texture and presence, particularly where structure and warmth are desired. 

For trousers

Mid to heavier cloths help trousers hold their line and drape cleanly through repeated wear.

Wool and longevity

Fox Brothers is proud to support The Campaign for Wool, an initiative dedicated to raising awareness of wool as a natural, renewable fibre.

Wool’s ability to regulate temperature, breathe, and recover its shape is central to the way our cloth performs across weights and seasons. These inherent qualities are why wool has remained the foundation of fine tailoring for centuries, and why cloth woven to the right weight continues to wear well over time.

Why weight matters beyond warmth

Cloth weight is often associated with temperature, but its influence extends further. Weight affects drape, crease recovery, and how a garment settles on the body. A heavier cloth may wear cooler than expected due to open weave, while a lighter cloth can feel warmer when worn close and structured. Understanding weight alongside weave and finish leads to better, longer-lived garments.

Selecting cloth with confidence

There is no single correct cloth weight. The right choice depends on when the garment will be worn, how often it will be used, and the character you wish it to have.

Some cloths earn their place through frequent wear. Others are chosen for specific seasons or settings. Understanding cloth weight simply allows you to choose with clarity and intention.

The Fox Brothers approach to cloth weight reflects a long-standing philosophy of considered use, overseen today by Managing Director Douglas Cordeaux.
