Choosing the best fabrics for custom hoodies comes down to one number above all others: GSM — grams per square metre — which determines the weight, warmth, durability, and perceived quality of the finished garment. The best fabrics for custom hoodies GSM guide covers every weight range from 280 GSM lightweight fleece to 500 GSM ultra-heavyweight, so clothing brands can specify exactly the right fabric for their market, climate, and retail price point before committing to production.

What Is GSM and Why Does It Matter for Custom Hoodies?
GSM stands for grams per square metre — a standardised measurement of fabric weight. A higher GSM means heavier fabric: more yarn per square metre, more fabric thickness, more warmth, and higher raw material cost. A lower GSM means lighter fabric: less yarn, more drape, less warmth, and lower raw material cost. For custom hoodies, GSM is the single most important specification after the fibre composition — it determines everything from how the hoodie feels in the hand to how it performs in wash and wear over time.
Furthermore, GSM directly affects retail price positioning. A 280 GSM hoodie retails credibly at USD 40–70. A 320 GSM hoodie retails credibly at USD 60–120. A 380 GSM hoodie retails credibly at USD 90–180. Choosing the wrong GSM for the target retail price creates a perception mismatch — a hoodie that feels too thin for its price point generates returns and negative reviews, while a hoodie that feels heavier than its price suggests is effectively leaving margin on the table.
What Are the Main Fabric Types Used for Custom Hoodies?
Three fabric constructions dominate custom hoodie production. First, cotton fleece — the most common hoodie fabric globally. Cotton fleece has a smooth face, a soft brushed interior, and excellent printability. It suits screen print, DTG, embroidery, and puff print decoration. Second, French terry — a lighter-weight loop-back fabric with a smooth face and looped (not brushed) interior. French terry is breathable and popular for gym-adjacent hoodies where breathability matters. Third, cotton-polyester blend fleece — typically 80% cotton / 20% polyester or 60% cotton / 40% polyester. Polyester improves shape retention, reduces shrinkage, and lowers cost relative to 100% cotton at the same GSM.
Additionally, organic cotton fleece is available for brands targeting sustainability-conscious consumers — GOTS-certified organic cotton fleece is available in the 280–380 GSM range. Recycled cotton or GRS-certified recycled polyester blends are available for brands with specific sustainability credentials. Ready One advises on fibre composition options at the quote stage based on the brand’s target market and certification requirements. See Ready One’s full custom hoodie manufacturing service.
GSM Guide: Which Hoodie Weight Is Right for Your Brand?
Selecting the correct GSM is the most important fabric decision a hoodie brand makes. The choice depends on target climate, retail price point, end use, and competitive positioning. Here is a practical guide to every relevant GSM range for custom hoodies — with the target use case, retail positioning, and key trade-offs for each weight.
240–280 GSM: Lightweight Hoodies for Warm Climates and Layering
240–280 GSM is the lightest range appropriate for hoodies. At this weight, the fabric is soft and drapey — suitable for mild climates, indoor use, and brands in UAE, South East Asia, or warmer US states. 260 GSM is the standard weight for fast-fashion and lower-cost private label hoodies. The trade-off at this weight is durability — 260 GSM hoodies show wear faster than heavier alternatives and feel noticeably thin in the hand at retail. However, for brands targeting AED 60–100 or USD 30–55 retail price points in warm markets, 260–280 GSM is the correct specification.
In addition, 280 GSM is commonly used for French terry hoodies and zip-ups intended for gym and activewear use — where breathability is prioritised over warmth. Many Australian activewear brands specify 280 GSM French terry for hoodies that double as gym cover-ups in air-conditioned environments.
300–340 GSM: Mid-Weight Hoodies — the Most Versatile Range
300–340 GSM is the most commercially versatile range for custom hoodies. At 320 GSM — the industry sweet spot — the fabric feels substantial in the hand, washes and wears well over time, holds embroidery and screen print decoration cleanly, and retails credibly at USD 60–130 depending on brand positioning. 320 GSM cotton fleece is the standard specification for streetwear brands, lifestyle labels, and premium casual brands globally.
Specifically, 320 GSM is the most popular hoodie specification at Ready One — ordered by brands in the UK, USA, Canada, Australia, and across Europe. It suits four-season markets and is the correct weight for any brand positioning their hoodie as a premium everyday staple rather than a performance or ultra-luxury product. If a brand is unsure of the right GSM, 320 GSM cotton fleece is almost always the correct starting point.
360–420 GSM: Heavyweight Hoodies for Premium and Cold-Climate Brands
360–420 GSM is the heavyweight range — fabric that feels unmistakably premium in the hand and performs in genuine cold-weather conditions. At 380 GSM, a custom hoodie feels noticeably heavier than most retail hoodies the buyer has previously purchased — this weight differential is a key selling point for brands positioning against mass-market competitors. 380 GSM cotton fleece retails credibly at USD 90–180 and supports strong brand storytelling around quality and craftsmanship.
Moreover, 400–420 GSM is entering ultra-heavyweight territory — used by brands specifically marketing “the heaviest hoodie you’ve ever owned” as a key product claim. At this weight, pilling resistance is excellent, the garment holds its shape through hundreds of washes, and the thermal performance is comparable to light outerwear. The trade-off is higher raw material cost and slower production — sewing machines must be calibrated for heavier fabric.
450–500 GSM: Ultra-Heavyweight for Niche Premium Brands
450–500 GSM represents the extreme end of hoodie fabric weight — typically used by brands making premium weight a core marketing claim. At 500 GSM, the hoodie is the heaviest commonly manufactured — double the weight of a standard 250 GSM fast-fashion hoodie. This range has a niche but loyal market among consumers specifically seeking maximum weight and durability. Production complexity and raw material cost are highest at this weight range. Ready One manufactures in this range from 50 units on request.
As a result, brands should choose their GSM based on honest assessment of their target climate, retail price point, and competitive positioning — not on what sounds most impressive. A 500 GSM hoodie is wrong for a UAE streetwear brand. A 280 GSM hoodie is wrong for a Canadian winter brand. The right GSM is the one that serves the customer’s actual need.

Frequently Asked Questions
What GSM is best for a custom hoodie?
320 GSM cotton fleece is the most popular and commercially versatile GSM for custom hoodies. It feels premium in the hand, wears well over time, holds decoration cleanly, and retails credibly at USD 60–130. For warm-climate markets, 280 GSM is more appropriate. For cold-climate premium brands, 380 GSM is the correct choice. The right GSM depends on the target climate, retail price point, and brand positioning.
What is the difference between cotton fleece and French terry for hoodies?
Cotton fleece has a smooth face and a soft brushed interior — the most common hoodie fabric construction. French terry has a smooth face and a looped (not brushed) interior — lighter, more breathable, and better suited to gym-adjacent or warm-climate use. Cotton fleece is warmer and more suitable for cold-weather markets. French terry is more breathable and better suited to activewear and mild-climate markets. Both are available at Ready One from 50 units.
Does a higher GSM hoodie always mean better quality?
Not necessarily. A higher GSM means heavier fabric — which is better for cold climates, durability, and premium retail positioning. However, for warm-climate markets or gym-adjacent use, a lower GSM fabric may be the correct specification. Quality also depends on fibre composition, yarn quality, and construction — a well-made 320 GSM hoodie in high-quality cotton is a better product than a poorly-made 400 GSM hoodie in low-grade fibre. GSM is one quality indicator, not the only one.
What hoodie GSM does Ready One specialise in?
