How Joggers and Sweatpants Are Made: Fleece Weights, Rib, Drawcords and What Moves the Price

A jogger is a fleece or French terry trouser with an elasticated waist and, usually, a ribbed cuff, and almost everything that decides how it wears and what it costs is settled before the first piece is cut: the fabric family, the weight, the waistband construction and the rib. This guide walks through those decisions the way we work through them on our floor in Narayanganj, so you can specify a jogger rather than just ask for one.

French terry or brushed fleece?

Both start as a cotton knit with a smooth face and a looped back. Leave the loops as they are and you have French terry, sometimes called loopback: it breathes, drapes and wears for most of the year. Brush the loops and you have fleece: warmer, softer, and heavier for the same yarn, but a cheap base yarn pills once it is brushed. For a year-round or warm-climate range we usually steer to terry; for a winter range, or a customer who buys the jogger for the softness, fleece. Our guide to French terry goes deeper on the fabric itself.

What weight should a jogger be?

Fabric weight is stated in grams per square metre, and for joggers the working range is 280 to 450 GSM. Below 280 the trouser is a lounge pant; above 450 it is a winter garment that takes a long time to dry. The premium sweet spot most brands settle on is 320 to 400 GSM, heavy enough to hold a shape and hide the knee, light enough to wear indoors. Weight is also the largest single price lever, because fabric is bought by the kilo and a trouser uses a great deal of it.

The waistband and drawcord

The standard construction is a covered elastic waistband with a flat drawcord through metal or embroidered eyelets. The elastic is a bought-in trim with its own supplier minimum, the channel that holds it is an extra sewing operation, and the eyelets are a third trim. A jacquard logo waistband, where the brand name is knitted into the elastic, is the upgrade most brands ask about; it looks like a far more expensive garment and costs a knitting minimum rather than a print run. One rule we apply without being asked: on children's sizes we do not fit functional drawcords at all, because the US, EU, UK and Canadian rules on cords on children's clothing restrict them, and a fixed decorative cord looks the same.

Cuffs, and why they go baggy

A cuffed jogger lives or dies at the ankle. The cuff is a separate rib, usually 2x2, and the failure everyone recognises, the cuff that has gone slack and wavy after a season, is a rib specification failure: no elastane, a loose gauge, or a strip of the body fabric used instead of rib. We knit cuff rib with elastane so the ankle keeps closing, and we dye body and rib in the same lot so the cuff is not a shade off the leg. Open-hem sweats skip the cuff and the problem, at the cost of the silhouette. Our rib knit guide covers the choice between 1x1 and 2x2.

Pockets, seams and the rise

Side-seam pockets are formed in seams that already exist, so they sit inside the standard price. Zipped pockets add a zip with its own minimum and a separate operation per pocket; a back patch pocket is one panel and one operation. Side seams versus a tubular leg is a construction choice rather than a cost one, and the rise, the inseam and the taper are the pattern decisions that make a jogger yours: we build the pattern from a reference pair you already like, then grade it across sizes with inseam options, as a one-off cost shared across the order.

Compacting, shrinkage and the sample

Cotton fleece shrinks. The finishing step that prevents a jogger losing a size in the first hot wash is compacting, a mechanical pre-shrinking of the fabric before it is cut, charged per kilo. We compact every fleece and terry we run, and we wash-test the pre-production sample so the measurements you sign off are the measurements after washing. That sample is sealed and every bulk piece is measured against it.

What moves the price of a jogger

• Weight and fabric family. A 450 GSM brushed fleece carries far more cloth than a 300 GSM terry, and brushing is an extra mill process.
• Waistband trims. Elastic, drawcord, eyelets and a jacquard band are bought-in trims with minimums that are spread thinly across a 100-piece run.
• Pocket configuration. Zips and patch pockets add trims and operations; side-seam pockets do not.
• Compacting and elastane rib. Small per-piece costs that decide whether the garment survives the first wash and the first season.
• Colourways and sets. Every colour is its own dye lot and its own 100-piece minimum; a matching hoodie doubles the fabric booking.
• Volume. Pattern, sampling and set-up are one-off costs, so unit price steps down at the usual breaks. The MOQ calculator shows how a colour split changes the total.

What to send us

A reference pair, or a photo of one, and four answers: terry or fleece, the weight band, cuffed or open hem, and how many colours. From that we propose the rib, the waistband build and the pocket set, sample it, wash it and send the measurements. If you have a tech pack, better; if you do not, the free template has the jogger fields already laid out. We make joggers and sweatpants from 100 pieces per style and colour, delivered DDP.
