dimensions and specs the dimensions are typical for every liner. the purpose of the construction is to provide“one size fits most”for the consumer. all of the dimensions are finished length, seam size and configuration must be added. 这个尺寸是帽子的常规尺寸。这款设计是为了同一个尺寸可以适合大多数顾客。所有的长度，接缝的尺寸都是成型后的。materials- i will need the manufacturer to purchase materials, i do not have the means to find and purchase the materials that i would like to use. the main material for the liner has to be breathable, and expand and contract. my thought for this is a cotton/poly blend. i will need different patterns on the material as well (american flag, camo, and other patterns down the line). if possible i would like to do custom logos, so if you can provide a minimum order, or if you are capable of doing this on a cotton/poly blend material? i would also like to use a coolmax, or similar material, this can just be a solid color, or custom logo if possible.材料：我没有办法找到我想要的材料，我需要供应商去购买。帽子的主要材料必须是透气、可伸缩的。我觉得是棉跟聚的混合物，材料上要有不同的花样（像美国国旗、迷彩色以及其他的）。如果可以还需要做客户的标签.你们的小订单量是多少？你们有没有能力用这个材料做？我还想用coolmax，或者类似的材料做另一款单一颜色的，如果可以也要加客户商标。 inner liner- the inner liner has to be moisture absorbent, a tightly woven and dense terrycloth would be ideal, possibly with a neoprene backing. similar products would be considered. again this will be inclusive to all liners.内衬：内衬必须是散汗的，厚实的毛圈织物比较理想，用合成橡胶做衬垫。相似产品也可以考虑。所有内衬都用这种。attachments- heavy duty elastic, attached by velcro, standard for all liners.附加：松紧带要牢固的，用
