FAQs About Wholesale Swim Trunks
1. Will the colors on my custom swim trunks stay bright after swimming?
Absolutely. LeelineApparel prints your designs using a special dye-infusion process that locks colors deep into the fabric fibers. While most brands print designs on the surface where chlorine and saltwater can wash them away, our method makes the pattern part of the material itself.
2. Can you add pockets or extra features to swim trunks?
Yes, and securely. LeelineApparel bonds waterproof zipper pockets, mesh lining, and accessory loops using sonic welding technology instead of traditional stitching. This creates a watertight seal so pockets stay dry inside while preventing fabric tears around the edges.
3. Do you accommodate plus-size customers?
We specialize in sizes up to 48-inch waist with purpose-built patterns. LeelineApparel doesn’t just scale up regular sizes. We redesign the crotch depth, leg width, and support features for natural comfort.
Our reinforced “Flex-Tech” waistbands with internal drawcords provide gentle hold without pinching. And we use extra-stretch fabrics that won’t sag when wet.
