360 GSM Extreme-Heavy Fabric
The absolute limit of wearable fabric. Blanket-weight warmth, enveloping drape, and ultra-plush textures — the fabric behind the blanket hoodie phenomenon, shipped to 40+ countries.
What Is 360 GSM Extreme-Heavyweight Fabric?
360 GSM extreme-heavyweight fabric sits at the absolute ceiling of what can still be called "wearable" fabric. At this density, the textile crosses a perceptual threshold — it stops feeling like clothing and starts feeling like a wearable blanket. This is the weight that powers the blanket hoodie trend, extreme cold-weather gear, and ultra-premium statement pieces.
The star constructions at 360 GSM are mink fleece, coral fleece, and Sherpa fleece — ultra-plush fabrics with deep piles that simply don't exist below 300 GSM. Mink fleece in particular, with its silky-fine dense pile, is almost exclusively produced in the 340–400 GSM range because lighter weights can't support the pile structure.
Quality control at 360 GSM is our most demanding process. Every batch is tested for shrinkage (<2% post-compaction), pilling resistance (Grade 4–5), colorfastness (Grade 4–5), thermal resistance (ASTM D1518), pile retention after washing, and tensile strength per ASTM D5034. At this price tier, zero defects is the only acceptable standard.

360 GSM Fabric Options
At 360 GSM, the fabric types are dominated by ultra-plush constructions that can't exist at lower weights.

What 360 GSM Delivers
At this extreme weight, every property is at its absolute maximum — this is the heavyweight champion.
Blanket-Level Warmth
The highest thermal retention in any wearable fabric — wraps the body in genuine blanket-weight insulation.
Ultra-Plush Hand Feel
Mink and coral fleece at 360 GSM produce the softest, most luxurious texture in the entire fleece family.
Complete Wind Block
The ultra-dense knit is virtually impermeable to wind — functions as a full wind barrier without any coating.
Zero Pilling (Grade 4–5)
The extreme fiber density makes surface pilling physically impossible — garments stay pristine for years.
Enveloping Drape
Unlike 320 GSM which holds rigid structure, 360 GSM flows and wraps around the body like a cocoon.
Indestructible Durability
The heaviest, most abuse-resistant fabric in sportswear — outlasts every other weight by a wide margin.
Substantial Weight Perception
The physical weight of the garment itself creates a premium, grounded feel that customers find deeply satisfying.
Extreme Cold Performance
With DWR treatment, provides genuine protection in sub-zero conditions — not just warm-weather layering.
What It's Used For
360 GSM serves a narrow but high-value set of applications — every product is a statement piece or extreme-performance garment.
320 GSM vs. 360 GSM vs. 400+ GSM
The extreme end of the spectrum — three tiers for three levels of maximum-weight demand.
| Property | 320 GSM | 360 GSM | 400+ GSM |
|---|---|---|---|
| Warmth | Very high | Maximum wearable Best Wearable | Extreme (non-wearable) |
| Hand Feel | Heavy, rich | Silkiest plush possible Best | Stiff, carpet-like |
| Drape | Structured, holds shape | Enveloping, wraps body Best | Rigid, doesn't drape |
| Wearability | Full garment Best | Oversized / relaxed only | Barely wearable |
| Breathability | Low | Very low | Near zero Tie |
| Mink/Coral Fleece | Not supported | Full pile development Best | Over-dense pile |
| Blanket Hoodie Vibe | Heavy hoodie feel | Genuine blanket feel Best | Actual blanket |
| Durability | Exceptional | Exceptional Tie | Exceptional |
| Print Quality | Very good Best | Good (deep pile) | Poor (fiber show) |
| Market Appeal | Broad winter market Best | Niche / trending | Very niche |
| Cost Per Meter | High | Very high | Highest |
| Best For | Winter hoodies | Blanket hoodies | Blankets / technical |
Honest Assessment
- The softest, most luxurious hand feel achievable in fleece — mink and coral textures are unmatched
- Blanket-level warmth in a wearable garment — the defining feature of the blanket hoodie category
- Enveloping drape that wraps and cocoons the body — creates a deeply satisfying wearing experience
- Ultra-premium perception — the heaviest weight commands the highest retail prices ($80–$150+)
- Complete wind and cold barrier — functions as standalone outerwear in extreme conditions
- Zero pilling (Grade 4–5) — the densest pile structure resists surface abrasion entirely
- Trend-driven demand — blanket hoodies and oversized pieces are one of the fastest-growing categories
- Ideal for limited drops and gift items — the weight itself becomes a marketing story
- Only suitable for oversized, relaxed-fit garments — zero tailored or fitted applications
- Extremely seasonal — 2–4 months of relevance in most markets (winter only)
- Highest fabric cost per meter in the wearable range — significantly impacts margins
- Very heavy shipping weight — air freight is often cost-prohibitive at this weight
- Out of the package, fabric can feel stiff — requires enzyme wash or garment dye to soften
- Deep pile can soften print detail — not ideal for fine-line or small-text screen printing
Best Printing Methods for 360 GSM
The ultra-deep pile at 360 GSM requires specific approaches — some methods work brilliantly, others struggle.

Screen Printing
Works well for bold, large-format designs with thick ink deposits. Plastisol inks perform best because they sit on top of the dense pile. Fine lines, small text, and halftones get lost in the deep texture — keep designs simple and impactful.

Embroidery
The clear #1 choice for 360 GSM. The fabric's extreme weight perfectly supports the heaviest embroidery — large, dense designs with 15,000+ stitches look incredible. No puckering, no distortion, no weight imbalance. The embroidery becomes a statement element.

Sublimation Printing
Available on 100% polyester 360 GSM mink and polar fleece. Works well for bold, large-format color blocks and gradients. Fine details and sharp edges are softened by the deep pile — embrace this as a design feature, not a limitation.
Make It Yours
360 GSM customization focuses on texture and feel — these treatments define the entire garment experience.
Pile Type
Mink (silky smooth), coral (ultra-soft), or Sherpa (curly textured) — each creates a completely different feel.
Pile Height
Standard pile, medium pile, or deep pile — controls how plush and how warm the fabric feels.
Enzyme Wash
Essential at this weight — softens the initial stiffness and pre-ages the surface for a lived-in feel.
Garment Dyeing
Pigment-dye finished garments for a vintage, faded look — extremely popular for blanket hoodies.
DWR Treatment
Water-repellent coating for snow-shedding and light rain protection on outerwear pieces.
Pre-Compaction
Critical at 360 GSM — mechanical pre-shrinking guarantees under 2% shrinkage after washing.
Ordering Process
Extreme-weight fabrics require careful planning — expect slightly longer timelines for the best results.
