Coolmax Socks for Private Label: Yarn Options and MOQ

Published: 2026-06-17By ZheSock TeamReading time: 5 min

Coolmax socks private label orders rarely fail because of the fiber name. They fail because the RFQ is vague. A buyer may ask for moisture wicking socks, but the factory still needs the Coolmax percentage, needle count, pair weight, cushion map, logo method, size split, packing format, and inspection level. Put those details in the first email. Then ask for two prices: a test order at 100 to 500 pairs and a repeat order at 1,000 to 3,000 pairs.

Choose the Coolmax Blend by Use Case

Coolmax is rarely the whole sock. Most export sport socks use 35% to 70% Coolmax polyester, with nylon for wear resistance and spandex for stretch recovery. Cotton can be added for a drier hand feel, but it slows drying after sweat or washing.

Match the blend to the job. For a running crew sock, a workable spec is 55% Coolmax, 38% nylon, 4% elastic, and 3% spandex. For a casual crew, 35% Coolmax, 45% cotton, 17% nylon, and 3% spandex is common. For cycling socks or gym socks, many buyers stay near 50% to 60% Coolmax to keep the sock thinner inside the shoe.

35% to 45% Coolmax: daily wear, light training, lower FOB cost.
50% to 60% Coolmax: running, gym, tennis, and most sport retail programs.
60% to 70% Coolmax: faster drying target, higher yarn cost, more synthetic hand feel.
Cost impact: moving from 35% to 60% Coolmax often adds USD 0.12 to USD 0.28 per pair, based on weight and yarn count.

Plan MOQ Around Yarn and Packaging

MOQ is not one fixed number. It changes by yarn color, logo method, sock height, and retail packing. If black, white, grey, or navy Coolmax yarn is in stock, a Coolmax socks private label test order can be much smaller than a dyed yarn order.

At ZheSock, some stock yarn programs can start from 100 pairs per style when the buyer accepts standard packing. For planning, 300 to 500 pairs per style and color is safer for first orders. Custom dyed yarn usually starts at 30 kg to 50 kg per color. That can equal about 800 to 1,500 pairs for light ankle socks, or 500 to 900 pairs for heavier terry crew socks.

Stock yarn test: 100 to 300 pairs per style, with higher unit price.
Normal private label run: 300 to 500 pairs per style and color.
Dyed yarn run: often 500 to 1,500 pairs per color, depending on grams per pair.
Printed belly band: usually 500 pieces minimum.
Retail box: usually 1,000 to 2,000 pieces minimum.

Set Needle Count, Gauge, and Weight

Needle count controls surface detail and fit. It also affects output speed. Common circular sock machines for Coolmax sport socks are 144N, 168N, and 200N. A 144N sock has a thicker face and works well for cushioned crew socks. A 168N sock is the normal choice for athletic retail socks. A 200N sock gives a finer face for running socks, cycling socks, and thin compression styles.

Ask the factory to quote grams per pair, not only yarn percentage. A 144N terry crew sock may use 45 g to 60 g per pair. A 168N half terry crew often sits at 38 g to 50 g. A thin 200N running ankle sock may use 28 g to 38 g. GSM can be estimated from the approved sample area, but grams per pair is easier to control in sock production.

144N: thicker body, good for full terry sole and outdoor crew socks.
168N: common starting point for private label athletic socks.
200N: finer face, closer fit, better for small jacquard detail.
Typical equivalent knit weight: about 220 to 380 GSM, depending on terry coverage and yarn count.

Build a Quote That Can Be Compared

A useful quote needs the same spec from every supplier. If one factory quotes 35% Coolmax on 144N and another quotes 60% Coolmax on 200N, the prices are not comparable. Lock the blend, needle count, sock height, cushion zones, logo size, packing, and order quantity before comparing FOB prices.

For export orders packed with a polybag or retail band, a basic ankle sock with 35% to 45% Coolmax often quotes at USD 0.85 to USD 1.25 FOB China at 1,000 pairs. A midweight crew sock with terry sole and 50% to 60% Coolmax often runs USD 1.35 to USD 2.10. Arch support, mesh instep, left and right shaping, and jacquard logo work can add USD 0.05 to USD 0.25 per pair.

100 to 300 pairs: expect 20% to 45% higher pricing than repeat orders.
1,000 pairs: better yarn use, lower setup burden, normal export costing.
3,000 pairs: stronger price point if the size and color split is simple.
Ask for price breaks at 300, 1,000, and 3,000 pairs before placing the test order.

Control Sampling and Bulk Lead Time

Sampling is where many delays start. A clear tech pack should include Pantone color, logo file, sock length in cm, foot length, cuff height, cushion map, size range, packing artwork, and target grams per pair. If those details are ready, sample knitting with stock yarn usually takes 5 to 10 days.

If yarn must be dyed, add 7 to 12 days for lab dip and cone dyeing after color approval. One sample revision is normal. Two revisions can still work. Three usually means the first brief missed key details, such as logo scale, calf tension, or terry position.

Sample with stock yarn: 5 to 10 days.
Lab dip and dyed yarn: add 7 to 12 days.
Bulk production at 500 to 3,000 pairs: 18 to 30 days after approval and deposit.
Multi color bulk orders: 35 to 45 days when several machines and packing lines are needed.
Air freight to the US or Europe: about 5 to 9 days. Sea freight port to port: about 28 to 45 days.

Inspect Fiber, Size, Color, and Packing

Quality control should start before bulk knitting. Check the yarn composition sheet, approved color swatch, first pair weight, stretch recovery, and logo position. Keep one signed approval sample in a sealed bag. The factory and buyer should both use it during bulk inspection.

For adult sport socks, a practical tolerance is ±0.5 cm on foot length and ±0.3 cm on cuff height. Pair weight should stay within ±5% of the approved sample. Color difference should stay near grade 4 on the grey scale after washing, unless the buyer accepts a lower standard for dark colors. Wash testing is usually done at 30°C or 40°C for 3 cycles to check shrinkage, twisting, and elastic recovery.

Inline check: review the first 50 to 100 pairs before full production continues.
Final inspection: use AQL General Inspection Level II with 2.5 for major defects and 4.0 for minor defects.
Common major defects: wrong size, broken toe seam, heavy oil mark, wrong logo, mixed color in carton.
Common minor defects: loose yarn end, light dirt, small packing wrinkle, slight band misalignment.
Certifications to ask about when relevant: OEKO-TEX, BSCI, Sedex, ISO 9001, GOTS, GRS, CE.

Frequently Asked Questions

What is the best Coolmax percentage for running socks?

For most running socks, use 50% to 60% Coolmax. It moves sweat well without pushing cost too high. A common spec is 55% Coolmax, 38% nylon, 4% elastic, and 3% spandex on a 168N or 200N machine.

Can I start Coolmax socks private label at 100 pairs?

Yes, if you use stock yarn colors, standard construction, and simple packing. At 100 pairs, the unit price is higher because setup, sampling, and packing work are spread across fewer pairs. For dyed yarn or custom boxes, plan for 500 to 1,500 pairs.

Is 144N, 168N, or 200N better for Coolmax socks?

Use 144N for thicker cushion socks, 168N for most athletic crews, and 200N for finer running or cycling socks. The right choice depends on pair weight. A 168N half terry crew at 40 g to 50 g per pair is a common private label starting point.

What FOB price should I expect for private label Coolmax socks?

At 1,000 pairs, basic Coolmax ankle socks often quote around USD 0.85 to USD 1.25 FOB China. Midweight Coolmax crew socks with terry sole often quote around USD 1.35 to USD 2.10. Logo method, cushion coverage, yarn percentage, and packing can move the price by USD 0.05 to USD 0.25 per pair.

What should I check before approving bulk production?

Approve the physical sample, not only a photo. Check foot length, cuff height, pair weight, logo position, stretch, color, and packing. Ask for bulk inspection under AQL Level II, with 2.5 for major defects and 4.0 for minor defects.
