Product Title

128GSM Weft Knit Small Mesh 100% Polyester Ultra Lightweight Breathable

1. Introductory Paragraph (Fully Around Title Selling Points)

This 128GSM weft knit small mesh fabric is made from 100% polyester and engineered specifically for sportswear and accessories that demand extreme lightweight, high breathability, and a soft hand feel. The weft knitted structure provides excellent crosswise stretch and a soft drape, while the small mesh openings allow air to circulate freely while maintaining adequate opacity. At 128 grams per square meter, this fabric is ultra‑lightweight – a full‑size training vest or shoe upper panel weighs only about 100‑120 grams, making it nearly unnoticeable to the wearer. The 100% polyester composition ensures excellent moisture wicking (sweat evaporates in about 18 minutes) as well as resistance to shrinkage and wrinkling. For sportswear linings, shoe uppers, hat side panels, and backpack pockets, this ultra‑light breathable weft knit small mesh delivers superior airflow and freedom of movement.

4. Frequently Asked Questions (Product‑Specific)

Q1: How does 128GSM small mesh compare to 150GSM or heavier meshes?
128GSM is one of the lightest grades available – thinner, more breathable (280‑340 CFM vs. 220‑260 CFM), and faster drying than 150GSM. It is designed for ultra‑light applications like race vests and summer base layers. The trade‑off is slightly lower tear strength (>18N), which is still sufficient for normal sportswear use. For higher durability, a 150‑170GSM version is available.

Q2: Is this fabric see‑through? Can light colors show skin?
Dark colors (black, navy, royal, charcoal) are fully opaque. Light colors (white, light grey, pastels) may be semi‑sheer when stretched due to the mesh structure. For light‑colored outer garments, we recommend using a liner or choosing a dark color. As a lining or base layer, slight sheerness is acceptable.

Q3: What are the advantages of weft knit compared to warp knit small mesh?
Weft knit small mesh offers better crosswise stretch and a softer, drapable hand feel – more comfortable against the skin. Warp knit mesh is more dimensionally stable but stiffer. For running singlets and linings, weft knit is the preferred choice.

Q4: Is a recycled polyester version available for this 128GSM small mesh?
Yes. We offer a GRS‑certified recycled polyester version of this exact 128GSM weft knit small mesh. The recycled yarn is sourced from post‑consumer PET bottles. The breathability (280‑340 CFM), drying time (18 minutes), tear strength (>18N), and snag resistance (Grade 3.5) are all within 5% of the virgin version. The recycled fabric also maintains the same soft hand and colorfastness. Minimum order for recycled is 800 meters. Please request a recycled swatch and a copy of the GRS certificate for verification.

Q5: How do I care for garments made from this mesh?
Machine wash cold (30°C) with like colors. Do not bleach. Tumble dry low or hang dry – the quick dry property means line drying takes about 1 hour. Do not use fabric softener; it can coat the fibers and reduce breathability. Avoid ironing directly on the mesh. Following these steps, the fabric will retain its performance for over 50 washes.

Q6: Can this fabric be sublimation printed?
Yes. The 100% polyester surface accepts sublimation ink well. Because the mesh is fine, the print will have a slight dotted texture, but team names and numbers remain sharp. For full‑coverage solid prints, a solid jersey is recommended. We offer a white version as a ready‑to‑sublimate base.

Q7: What are the custom color options and MOQs?
For custom Pantone matching, the minimum order is 500 meters with a lab dip lead time of 25-30 days. Pre‑production samples are available.
