The difference between summer and winter clothes goes far beyond sleeve length. Fabric, weight, construction, trims, timelines, and even the factories that make them change from one season to the next. For a brand planning both collections, these differences decide which summer and winter clothing manufacturers you should use, when you need to order, and what each range will cost. This guide explains the five key differences from a factory’s point of view, and how to plan a summer collection and a winter collection without missing either season.
Difference Between Summer and Winter Clothes: 5 Key Points
| Factor | Summer Clothes | Winter Clothes |
|---|---|---|
| 1. Fabric | Cotton jersey, slub, viscose, linen-look blends | Fleece, French terry, interlock, knitted sweaters, wool blends |
| 2. Weight (GSM) | Around 140 to 180 GSM | Around 280 to 500 GSM for fleece and terry |
| 3. Construction and trims | Simple seams, few trims | Hoods, zips, rib cuffs, linings, more operations |
| 4. Cost per garment | Lower, as less fabric is used | Higher, mainly because of fabric weight |
| 5. Timeline | Shorter production, simpler fabric | Longer, with heavier fabric and busier factories |
1. Fabric: Breathable vs Insulating
Summer fabrics are chosen to let heat escape: single jersey cotton, slub textures, viscose, and lightweight blends that dry quickly. Winter fabrics trap warm air: fleece is brushed on the inside to create insulating loops, French terry keeps loops on the back for lighter warmth, and knitted sweaters use thicker yarns. Our explainer on fleece and French terry covers the winter fabrics in detail, and our guide to single jersey fabric covers the summer side.
2. Weight: GSM Makes the Season
GSM, or grams per square metre, is the simplest way to tell summer from winter fabric. Most summer t-shirts sit around 140 to 180 GSM, while winter hoodies and sweatshirts usually run from about 280 GSM for a standard weight to 400 GSM and above for heavyweight styles. Our guide to hoodie GSMs shows where each weight fits.
3. Construction and Trims
A summer tee or tank is a few panels and simple seams. A winter hoodie adds a lined hood, rib cuffs and hem, a kangaroo pocket, sometimes a zip, and drawcords, each of which adds operations, materials, and checks. Winter wear manufacturers therefore need more sewing time per piece, and trims must arrive before cutting starts.
4. Cost: Fabric Drives the Difference
Because fabric is often around 70% of a knit garment’s price, heavier winter fabric raises the cost far more than extra sewing does. A basic cotton tee from us is roughly $2 to $3.50 FOB, while a 300 GSM hoodie is about $6.60 and a 500 GSM hoodie about $12.50. Our hoodie cost breakdown shows exactly how the fabric weight changes the price.
5. Timeline: When to Order Each Season
For a summer collection, work back from your launch date. Allow about a month for sampling, our standard 75 to 90 days from purchase order to shipment for knitwear, and four to six weeks of sea freight, which puts your first purchase order around six to seven months before the season. Winter collections need longer, because heavier fabrics take more processing and the busiest production months fill up early, so plan seven to eight months ahead. Our guide to clothing line production breaks down each stage.
Choosing Summer and Winter Clothing Manufacturers
Some factories specialise in one season; others make both. In India, Tirupur is strong in cotton summer knits and in fleece and French terry for winter, while woollen knitwear is concentrated in Ludhiana; our guide to the top clothing manufacturing states in India shows where each product is made. When comparing winter clothing manufacturers in India, ask about heavy fabric sourcing, brushing and finishing, and capacity in the busy months. For summer, ask about lightweight fabric consistency, shrinkage control, and print quality. Using one manufacturer for both seasons keeps fit, labels, and quality consistent across your range. Brands in Europe can see our page for hoodie manufacturing for European brands.
Our recommendation
Plan both seasons together. Lock summer fabrics and fits six to seven months ahead and winter seven to eight months ahead, specify GSM for every style, and confirm trims before cutting. We make cotton knitwear for both seasons in Tirupur, from 160 GSM tees to 500 GSM hoodies, with knit orders starting at 300 pieces per colour per style.
Frequently Asked Questions
What is the difference between summer and winter clothes?
Summer clothes use lighter, breathable fabrics around 140 to 180 GSM with simple construction. Winter clothes use heavier insulating fabrics such as fleece and French terry at 280 GSM and above, with more trims, higher cost, and longer production.
How far in advance should I manufacture a summer collection?
Place your first purchase order about six to seven months before the season: around a month for sampling, 75 to 90 days for knitwear production, and four to six weeks for sea freight.
What do winter wear manufacturers need to plan for?
Heavier fabric sourcing and processing, more trims such as zips and rib, longer sewing time per piece, and busier factories in peak months, so orders should be placed seven to eight months ahead.
Where are winter clothing manufacturers in India located?
Tirupur is strong in cotton fleece, French terry, hoodies, and sweatshirts, while Ludhiana is the main centre for woollen knitwear.
Can one manufacturer make both summer and winter clothes?
Yes. Many knitwear factories make both, and using one partner keeps fit, labels, and quality consistent across your range.
