Buying Guide

Choose the right dimensions

Pick mailer sizes that accommodate folded sweatshirts—common useful formats include around 14.5x19 in for single items and 24x24 in for bulkier or multiple pieces

Prioritize waterproof, tear-resistant materials

Poly mailers resist moisture and tearing during transit, protecting fabric finishes and prints on sweatshirts better than paper alternatives

Use reliable self-seal closures

Strong self-sealing adhesive streamlines packing and reduces the need for extra tape, improving speed for high-volume shipments

Consider color and branding needs

Colored options like navy, teal, or purple help with brand identification and inventory sorting while milky-white gives a neutral look

Balance pack quantity and per-unit cost

Bulk packs (100–200 count) lower per-mailer cost; choose a count that matches your shipping volume to optimize storage and cash flow
