Best Fabric for Workwear – Weight & Composition Explained
Choosing workwear isn’t just about picking a colour and slapping a logo on it. Finding the best fabric for workwear means understanding what’s underneath — how long the garment will last, how comfortable your team will be wearing it for an 8-hour shift, and even how well your logo or design will sit once it’s decorated. Get the fabric wrong and you’ll be reordering within a year — get it right and a well-chosen uniform can last several seasons of regular wear and washing.
This guide breaks down the practical factors — weight, fibre content, and finish — so you can identify the best fabric for workwear that matches the demands of each role.
Understanding Fabric Weights – GSM
GSM stands for “grams per square metre” and is the standard way the garment trade measures how heavy or substantial a fabric is. As a rough guide:
| GSM Band | Garments | Typical Fibre Comp. | Embroidery | |
|---|---|---|---|---|
| 130–165 | Lightweight t-shirts (crew neck, V-neck, polyester tees) | 100% cotton, 100% polyester, recycled polyester, cotton/elastane blends | Possible for small logos with a backing/stabiliser, but large designs risk puckering and show-through on the reverse | Recommended — the best weight for large or detailed designs |
| 165–220 | Standard and long-sleeve t-shirts, t-shirt alternatives | 100% cotton, BCI cotton, organic cotton, 60/40 cotton-poly blends | Suitable for logos and wordmarks, especially on ringspun or combed cotton | Suitable for all design sizes; still the better choice for detailed or multi-colour designs |
| 190–245 | Polo shirts (polycotton pique), heavyweight workwear tees, catering aprons | 50/50 cotton-polyester pique, polycotton or recycled polyester blends | Recommended — pique and heavier cotton fabrics hold stitching cleanly | Limited — the ribbed pique texture distorts printed designs, so large prints aren’t recommended on polo shirts |
| ~220 | Anti-pill fleece jackets, gilets, and bodywarmers | 100% polyester fleece | Recommended — the standard decoration method for fleece | Not recommended — the brushed, textured pile doesn’t hold a printed design |
| 240–340 | Sweatshirts and hoodies (standard weight) | 70–80% cotton, 20–30% polyester blends | Suitable for chest and sleeve logos | Suitable for large front or back designs |
| 340–450 | Heavyweight sweatshirts and hoodies | 80% cotton, 20% polyester, BCI cotton blends | Suitable, including larger chest or sleeve designs | Suitable, including large full-front or full-back graphics |
Across our own range, t-shirts span from around 130gsm up to 350gsm for heavyweight styles, while sweatshirts and hoodies typically run from 240gsm up to 450gsm for the heaviest fleece-back options. Polo shirts in a polycotton pique generally sit between 190gsm and 240gsm, with polyester performance polos coming in lighter at around 130gsm.
As a general rule: the lower the GSM, the better the fabric drapes and breathes, but the more it shows seams, stitching and any unevenness underneath a printed design — and the more careful you need to be with embroidery, which can pucker or show through on thin fabric without a stabiliser backing. The higher the GSM, the more structure and durability you get (and the more room embroidery has to sit cleanly), at the cost of some breathability. Understanding GSM is one of the most useful starting points when determining the best fabric for workwear for your team.
A Note on Technical Outerwear
Softshells, shell jackets, and padded bodywarmers don’t fit neatly into the table above. These are multi-layer, bonded or laminated constructions… — typically a 100% polyester outer (anywhere from around 60gsm to 270gsm depending on the layer) combined with separate lining and padding layers, often with waterproof membranes or coatings. The GSM figure for any one layer doesn’t tell you much about how the finished jacket behaves, so these are best treated as their own category: for smooth softshell jackets, printing is a great option for both small and large designs provided there is no outer PVC/Waterproof coating. Embroidery is a great choice too for smaller designs, just keep in mind they won’t usually look as crisp and defined as a printed garment. It’s important to note that garments with sewed baffles (padded sections visible on the outer layer) can have printed or embroidered designs applied, but ideally the design needs to be within 1 baffle section, especially for prints; not crossing over the section line. In any case, embroidery tends to be a better option for this garment style due to the sections often creating an uneven surface & the material usually being more sensitive to the heat applied during the print process.
Fibre Composition: Choosing the Best Fabric for Workwear
Soft, breathable, and the most comfortable option against the skin — 100% cotton is often considered the best fabric for workwear in indoor roles where people are on their feet all day. Cotton takes dye well and tends to feel “premium,” but it’s more prone to shrinkage on a hot wash and can lose shape faster than blended fabrics under heavy use. Many of our cotton tees use ringspun or combed cotton, which produces a smoother surface than standard open-end cotton — useful if you’re decorating with embroidery, as a smoother weave gives the stitching a cleaner finish.
Durable, quick-drying, and highly colour-stable — polyester resists shrinking and fading even after repeated industrial washing. It’s the standard choice for technical outerwear (softshells, fleeces, padded gilets) and for performance polos where moisture management matters. The trade-off is breathability: polyester doesn’t absorb moisture the way cotton does, which is why it’s less common for everyday t-shirts but standard for jackets and fleeces.
Blends — commonly 50/50, 60/40, or 80/20 cotton-to-polyester — aim to take the best of both fibres. The polyester content reduces shrinkage and improves wash durability, while the cotton content keeps the fabric breathable and comfortable. For many buyers, a polycotton blend is the best fabric for workwear across a wide range of roles — it’s the dominant type for sweatshirts and hoodies in our range (typically 70–80% cotton, 20–30% polyester) and for polycotton polo shirts (usually 50/50). For workwear that’s washed daily or several times a week — catering aprons, for example — a polycotton or recycled polyester blend in the 200–245gsm range holds its shape and colour far better over time than pure cotton.
Matching the Best Fabric for Workwear to the Job
Lighter polycotton polos (190–240gsm) or cotton tees (165–220gsm) give a smart, breathable look for indoor environments where comfort over a full shift matters more than heavy-duty protection.
Look for polycotton or recycled polyester blends around 200–245gsm. These fabrics are built to withstand frequent 50–60°C washes (standard for catering uniforms) without breaking down, and the polyester content resists staining better than pure cotton.
For outdoor and trade roles, the best fabric for workwear is typically a heavier cotton/polyester sweatshirt or hoodie (280gsm+) for warmth and durability in cooler environments. Technical outerwear — softshells, padded bodywarmers, and shell jackets, almost always 100% polyester with specialist coatings — handles wind, rain, and abrasion. Anti-pill polyester fleeces (around 220gsm) sit in between, offering warmth without bulk.
Mid-to-heavyweight cotton/poly sweatshirts and hoodies (300gsm+) give a substantial, premium feel that holds up well to repeated decoration and washing, making them a popular choice for retail drops and team merchandise.
Fabric and Decoration: A Quick Note
Once you’ve identified the best fabric for workwear in your environment, decoration is the next consideration. The fabric you choose also affects how well embroidery or printing will sit on the finished garment. As a general principle, heavier, more stable fabrics (workwear tees over 180gsm, sweatshirts, polo pique) handle embroidery well, while lighter, smoother fabrics (under 180gsm cotton) tend to be better suited to printing, especially for larger or more detailed designs. We’ve covered this in detail in our Embroidery vs Print guide — worth a read once you’ve settled on a fabric weight and want to plan your branding.
Sustainability and Accreditations
If sustainability credentials matter to your business or your customers, it’s worth knowing that many garments across our range are made using BCI (Better Cotton Initiative) cotton, GRS-certified recycled polyester, or organic cotton, and are produced under accreditations including OEKO-TEX 100, SEDEX, and Fair Labour standards. These details are listed on individual product pages and can be a useful point to highlight if you’re putting together a sustainability-conscious uniform programme. Data sheets are also available for most of our products on their respective product pages; if you need any help choosing garments with the right accreditations, please feel free to contact us.
Washing and Care
Workwear gets washed far more often than everyday clothing, so care instructions matter more than they might for a one-off event tee. The best fabric for workwear in high-wash environments is generally a polycotton or polyester blend — these tolerate higher temperatures and more frequent washing without significant degradation, which is why blended fabrics dominate the catering and hospitality end of the range. Cotton-rich garments generally need lower wash temperatures (30–40°C) and should be line-dried or tumble-dried on low to avoid shrinkage.
Final Thoughts
There’s no single answer to what’s the best fabric for workwear — only the right fabric for how the garment will actually be used. Start with the environment (indoor/outdoor, wash frequency, temperature), then narrow down by GSM and fibre content, and finally think about how it’ll take your branding.
