新西兰采购需求：健身棉质慢跑裤，慢跑裤，男士慢跑裤，男士氨纶慢跑裤批发商，OEM健身慢跑裤，纯色慢跑裤

I'm reaching out on behalf of North Bound Clothing, a streetwear brand in New Zealand. We're interested in ordering oversized men's sweatpants made from 100% cotton, specifically looking for styles with pockets. Our initial order would consist of 100 units each in black and grey colors, with a range of sizes from toddler to 3XL. Could you provide info on the cheapest printing methods available for this style? Additionally, please include the most affordable shipping options to Coopers Beach, NZ. A size breakdown or suggestions for the toddler-to-adult sizing would also be greatly appreciated. Looking forward to your response!
