英国采购需求：冬季外套、滑雪服、沙滩巾、披肩式毛巾、运动毛巾、超细纤维运动毛巾

I'm looking for a supplier who can manufacture a custom waterproof poncho for kids aged 5–12, using eco-friendly materials. Key specs include 100% recycled fabric with PFC-free waterproofing, an oversized fit for kids and their backpacks, adjustable hoods, elasticated wrists, and a packable design that folds into its own pocket. Essential features also involve reinforced seams, ventilation snaps, and an adjustable hem to grow with the child. Could you let me know if you're able to meet these specifications? I'm also interested in your minimum order quantities for both samples and production runs, as well as your typical lead times for both. Lastly, please confirm if you hold any eco-certifications like GRS or OEKO-TEX. Looking forward to your response!
