When outdoor brands develop a new fleece jacket collection, fabric selection directly affects product positioning, production cost, retail price, and customer expectations.
Choosing between polar fleece and cotton fleece is not simply a material decision. It determines how the jacket performs, where it can be sold, and what manufacturing requirements the factory must manage.
This guide covers what outdoor brands and OEM buyers need to know before committing to either construction.
A synthetic knit fabric, typically 100% polyester, produced by brushing the fiber surface to create a raised pile. The brushing process creates air pockets between fibers that trap body heat — which is where the insulation performance comes from. Fabric weight typically ranges from 100gsm (lightweight mid-layer) to 300gsm+ (heavyweight insulation layer).
For OEM production, polar fleece is generally easier to source consistently because polyester fleece has a more mature global supply chain and more stable performance between production batches.
Common polar fleece constructions used in OEM production:
| Construction | Weight | Typical Application |
|---|---|---|
| Microfleece | 100–150gsm | Base layer, lightweight mid-layer |
| Standard polar fleece | 200–250gsm | Mid-layer, casual outdoor jacket |
| Heavyweight fleece | 300gsm+ | Insulation layer, cold weather outer |
| Bonded fleece | Varies | Softshell inner layer, structured jackets |
| Grid fleece | 150–200gsm | Technical mid-layer, moisture management |
A knit fabric with a cotton-dominant composition — typically 80% cotton / 20% polyester, or 100% cotton. The inner surface is brushed to create a soft pile similar to polar fleece, but the fiber properties are fundamentally different. Cotton fleece is heavier, absorbs moisture rather than wicking it, and takes significantly longer to dry.
For brands ordering cotton fleece jackets, shrinkage control and color consistency become critical quality checkpoints during bulk production.
| Factor | Polar Fleece | Cotton Fleece |
|---|---|---|
| Fiber composition | 100% polyester (synthetic) | 80/20 cotton-poly or 100% cotton |
| Weight range | 100–350gsm | 280–450gsm |
| Moisture management | Wicks moisture away from skin | Absorbs moisture, slow drying |
| Warmth when wet | Generally maintains better warmth retention in damp conditions | Loses most insulation when wet |
| Breathability | High | Medium–High |
| Durability | High — resists pilling with quality yarn | Medium — prone to shrinkage and shape loss |
| Washing requirements | Machine wash, quick dry | Cold wash, low heat dry to prevent shrinkage |
| Material cost tendency | Generally lower | Generally higher for premium cotton |
| Retail positioning | Technical outdoor, performance | Lifestyle, casual, streetwear |
| Sustainability options | Recycled polyester (GRS certified) | Organic cotton (GOTS certified) |
From a manufacturing standpoint, polar fleece and cotton fleece require different handling at almost every production stage. These differences directly affect sampling timelines, bulk production risk, and final FOB price.
Polar fleece has a nap direction — the pile lies in one direction. Consistent cutting with the nap requires more precise layout planning and increases fabric waste by 8–12% compared with non-directional fabrics. Cotton fleece is more forgiving in layout but requires pre-washing to account for shrinkage before cutting begins.
Polar fleece requires flatlock or coverstitch seaming for stretch garments. Standard lockstitch seams on fleece can cause seam distortion during wear. Cotton fleece sews more like a standard knit but needs tighter tension control to prevent seam tunneling.
Polar fleece is dimensionally stable after washing and does not require ironing. Cotton fleece garments often require steam finishing before folding and packaging to maintain presentation quality — adding labor time and cost at the final QC stage.
Cotton fleece must be tested for shrinkage before bulk production. A 3–5% shrinkage rate is typical for untreated cotton fleece. Patterns must be graded to account for post-wash dimensions. Brands that skip this step receive garments that are one size smaller than specified after the customer's first wash — a quality issue that generates returns and damages brand credibility.
Your brand targets outdoor performance, hiking, skiing, or any activity where moisture management and warmth retention matter. Polar fleece is also the standard choice for corporate uniform programs and promotional outerwear where durability and easy care are priorities.
Recycled polyester fleece — made from post-consumer PET bottles with GRS certification — is increasingly standard for brands targeting European retail or sustainability-focused consumers. The performance is identical to virgin polyester fleece with a cost premium of typically 10–15%.
Your brand targets lifestyle, streetwear, or casual markets where softness, natural feel, and aesthetic matter more than technical performance. Cotton fleece is the standard fabric for hoodies, sweatshirts, and casual zip-ups sold outside the technical outdoor channel.
Organic cotton fleece with GOTS certification suits brands targeting premium lifestyle, yoga, or wellness markets. Cost is significantly higher than standard cotton fleece but opens access to specialty retail channels with strong sustainability requirements.
Many brands developing their own outdoor collection do not choose pure polar fleece or pure cotton fleece. Instead, they develop hybrid fleece products that balance comfort, durability, cost, and market positioning.
Common hybrid constructions used in OEM production:
Cotton-poly blend fleece (80/20) — softer hand feel than pure polyester, more dimensionally stable than 100% cotton. The most common construction for casual outdoor lifestyle brands
Polyester fleece outer with brushed inner layer — structured outer appearance with soft interior comfort, suitable for mid-layer jackets
Bonded fleece combined with softshell panels — technical performance at high-movement zones with fleece comfort at the body. Common in ski touring and alpine mid-layers
Fleece-lined windbreaker construction — lightweight shell outer with bonded fleece inner, suitable for everyday outdoor and urban use
These constructions allow brands to develop products positioned between technical outdoor and lifestyle markets — often at a retail price point that neither pure polar fleece nor cotton fleece alone can achieve.
This is where ODM development adds the most value. Rather than selecting from stock fabric options, brands work with the factory to engineer a specific construction that meets both performance requirements and cost targets.
Incomplete specifications at the development stage cause sampling delays and revision rounds that add cost and time. Confirm these before the first prototype:
Fabric specifications:
Fiber composition and ratio (100% polyester / 80:20 / 100% cotton)
Fabric weight (gsm) — directly determines warmth and hand feel
Pile height and brushing direction
Anti-pilling treatment standard
Certification requirement (GRS, GOTS, OEKO-TEX)
Construction specifications:
Seam type (flatlock, coverstitch, or bound seam)
Hem and cuff construction (ribbed, flatlock, or raw edge)
Zipper specification (full-zip, quarter-zip, brand and model)
Pocket construction and placement
Hood specification if applicable
Retail readiness:
Logo application method (embroidery, heat transfer, woven patch)
Label and hangtag specifications
Packaging requirements (poly bag, folding spec, carton marking)
Barcode placement for retail compliance
Care label requirements for target market
For brands building their own custom fleece jacket collection under a private label, the development process at RUINIU typically follows:
Category and fabric confirmation — polar fleece, cotton fleece, or hybrid construction; weight and certification
Pattern development — new pattern or modification of factory base pattern
Logo and branding — embroidery placement, woven label design, hangtag specification
Sample development — first sample in 7–10 days from confirmed tech pack
Fit and color approval — 2–3 revision rounds standard
Pre-production sample sign-off — all specifications locked before bulk production begins
Bulk production — 35–45 days standard lead time
Retail packaging — custom labels, hangtags, poly bags, barcode placement for retail-ready delivery
MOQ starts from 100 pieces per style/color for both polar fleece and cotton fleece jackets. For styles requiring custom fabric development or specialty yarns, MOQ may vary based on fabric mill minimums.
