Sweatpants fabric
Sweatpants Fabric: Terry, Fleece and Stretch Knits for Jogger Pants
Sweatpants fabric is judged inside and after wear: how the back feels on skin, how the knee and seat recover, and how the waistband and cuffs hold. Thirteen of our fabrics name trousers and jogger pants on their product pages, 155 to 270 g/m², in terry, brushed, double-knit, ponte and rib constructions; 6 contain spandex (7.4–26%). We hold dated, lot-referenced test records for 3. Product-page data checked on 6 November 2026.
Which fabric for your sweatpants or jogger pants?
Mibein's opinion, drawn from the weights, compositions and function statements on the product pages; not test results or a guarantee. Wear-test a sample in your color before you commit.
| If you are making… | Start with | Weigh against it |
|---|---|---|
| Classic sweatpants with a soft, cotton-like inside | Q36589 (220 g/m², French terry, looped back) | No stretch is stated, so plan ease and a rib waistband and cuffs; terry is generally heavier to wear than a jersey |
| Fitted jogger pants that move with the body | Y35700 (230 g/m², 15.6% spandex, single jersey), P35137 (200 g/m², 12% spandex), S35887 (235 g/m², 10% spandex, air-layer double knit with a shaping effect) | More spandex means more stretch but a different hand; judge knee and seat recovery on a sample |
| Warm jogger pants for cold weather | Q35526 (250 g/m², 20% spandex, brushed fleece), C25377 (240 g/m², 7.4% spandex, brushed back; pilling, snagging and anti-static records below) | Brushed backs are generally warmer and can show more pilling; C25377's pilling on the jacquard face is 2-3 at 50 pilling cycles and 4 at 600 cycles, and 3 on black at 50 cycles; see tests |
| Spandex-free jogger pants | TS2533 (220 g/m², Sorona), C23517 (260 g/m², Sorona, page says it keeps set bottoms from bagging at the knee), S35817 (190 g/m²) | No stretch percentage is stated; if fit depends on stretch, ask for a stretch and recovery result on your color |
| Lightweight or tailored track pants | S35808 (180 g/m², ponte, high two-way stretch that resists deformation), C23462-2 (155 g/m², Sorona) | Ponte-type knits look smoother than a terry; the lightest fabrics can show body shape |
| Travel or easy-care jogger pants | P35088 (215 g/m², wrinkle-resistant listed), L35200 (270 g/m², nylon blend, 26% spandex, rib, wrinkle-resistant listed) | Wrinkle resistance is a product-page statement; L35200 is high in spandex and nylon, so check the hand |
Weight, as our working guide (general guidance, not an industry standard): under 200 g/m² lighter track pants and summer jogger pants (3 fabrics); 200–239 everyday sweatpants and jogger pants (6); 240 and above heavier, warmer pieces (4). Knit weights are not comparable across constructions, so choose by the sample garment, not the number.
Loop back or brushed back? General background, not test results: a looped back (terry) is generally seen as more breathable; a brushed or fleece back generally feels warmer and fuller. Settle the back before the weight.
Three questions before you choose
Our opinion and general guidance, not test results.
- Which silhouette?A tapered, close jogger pant needs recovery at the knee and seat, so look at the spandex or Sorona options; a relaxed or wide-leg sweatpant works with the terry.
- Which season?Light track pants and summer jogger pants sit under 200 g/m²; cold-weather jogger pants use the brushed or fleece backs.
- How much?The product pages quote MOQ 150–400 kg per color and flexible supply below that; your quantity narrows the choice early.
Waistband, cuffs and pockets
General guidance and Mibein's opinion, not test results.
Waistband. Elastic, drawcord and self-fabric waistbands load the knit differently; decide the waistband first, because it sets how much stretch and recovery the body fabric needs.
Cuffs and hem. Rib cuffs where used need their own recovery and a matching shade; check dye lots side by side.
Pockets. Heavier fabrics generally carry pocket bags with less distortion than very light ones; test the pocket drop on the sample.
Common mistakes
General guidance and Mibein's opinion, not test results.
Choosing by g/m² alone. A 220 g/m² terry and a 220 g/m² jersey wear differently; the sample decides.
Ignoring knee and seat recovery. Bagging often shows up after wear, not on the swatch; wash and wear a sample.
Taking a function for a result. Abrasion-resistant, wrinkle-resistant and anti-static are product-page statements unless a result is shown in the test table.
Skipping the wash test. Wash a sample garment before you approve bulk and compare size, shape and color. We publish no shrinkage result for these fabrics.
To request samples, send: the garment (sweatpants, jogger pants, track pants), season, weight band, back (looped, brushed or smooth), fit and silhouette, waistband, color range and expected quantity.

The C25377 product page does not list anti-static; the record is shown because it is held. The C23462-2 light-fastness result (3-4) is published on our chino pants fabric page. GTTC is the laboratory named in our records (accreditation not recorded here). Each result applies only to the sample, color and lot named. Records that lack a recorded date, lot or color (and in some cases the laboratory), and records filed under a variant or different model code (for example P35088-2 or TS2533220G), are not counted. No other result is published on this page; none of the other 10 fabrics has one, and we publish no shrinkage, stretch-and-recovery or crease-recovery result. Contact us with your fabric and color to ask what records exist.
Frequently asked questions
What fabric is best for sweatpants?
There is no single best. A terry or brushed back suits relaxed, warm sweatpants; a spandex or Sorona jersey or double knit suits fitted jogger pants. The table above is a starting point; the wear-tested sample decides.
What GSM is best for jogger pants?
Our working bands, general guidance and not an industry standard, put lighter jogger pants under 200 g/m², everyday jogger pants at 200–239 and warmer pieces at 240 and above. See the fabric weight guide.
Do you have spandex-free stretch for jogger pants?
7 of the 13 have no spandex. The product pages state spandex-free stretch with good recovery for TS2533, C23517, C23462-2 (Sorona) and S35817. See 4-way vs 2-way stretch.
MOQ, lead time and samples
Product-page statements, not order commitments: MOQ 150–400 kg per color (the pages also say about 500–1,000 m per color; which figure applies to a given fabric is not stated); dyed stock ready to ship anytime; greige in stock 15–25 days; no greige in stock 35–45 days. For samples the pages say "When the fabric is in stock, we can meet virtually every sampling request." Ask us whether a report exists for your fabric and color.
