A custom polar fleece jacket should be specified by fabric weight, pile, brushing, anti-pilling finish, stretch, warmth, fit and intended layer position. “Polar fleece” alone does not tell a factory whether the brand needs a lightweight grid mid layer, everyday full-zip fleece or heavier outer layer.
Approve the actual fabric, colour and finish before the final sample. Similar-looking fleece can differ in recovery, pilling, shrinkage, shedding and surface appearance after washing.

Quick answer
Define the fleece by composition, weight, construction, pile, anti-pilling requirement, colour, stretch and care performance. Then match the pattern, seam type, pockets, binding and branding to the selected fabric.
| Direction | Best for | Development focus |
|---|---|---|
| Lightweight fleece | Active layering and mild weather | Low bulk, recovery and breathability |
| Midweight full zip | Outdoor, travel and uniform ranges | Fit, pockets, collar and everyday durability |
| Heavy fleece | Warm casual layers and cold conditions | Seam bulk, structure and garment weight |
| Grid or stretch fleece | Technical active mid layers | Stretch direction, recovery and panel design |
Fabric weight helps describe warmth and bulk, but it does not explain pile density, yarn, brushing or backing. Record width, composition, construction, face and back, stretch and approved hand feel alongside weight.
Fleece surfaces experience rubbing at cuffs, elbows, seat belts and pack straps. Set an appropriate pilling test and review washed appearance. Shedding and dimensional change can affect both customer experience and final measurements.
The pattern should allow the intended base layer and fabric stretch. Thick fleece needs clean seam allowances at collars, pockets and cuffs. Stretch styles may use different seam and binding choices from stable midweight fleece.
Add woven reinforcement only where abrasion or structure requires it.
Stabilise zipper and pocket areas without making the jacket stiff.
Test embroidery backing against comfort and distortion.
Match transfers and patches to the fleece surface and care cycle.
Keep labels comfortable against the neck and side seam.
Approve fabric code, colour, hand feel and pile direction.
Check fit over the intended layer.
Review collar, zipper, pocket and cuff bulk.
Test pilling, shrinkage, colourfastness and branding durability.
Compare bulk fabric with the approved swatch.
Record care instructions from validated results.
