Haiku bags typically include multiple slip pockets and interior zip pockets, card or RFID-blocking card pockets, pen holders, key fobs, and side or compartmented sections for organizing small items.
Many Haiku styles use water-resistant fabric, and several include RFID-blocking card pockets or slots to help protect cards and personal data.
Product descriptions commonly note recycled content, often listing the shell as 100% recycled polyester. Some styles specify the fabric is made from reclaimed plastic bottles (for example, “7+ bottles” or “12+ bottles”).
Care varies by style: many listings advise spot or wipe clean, and some explicitly state “Do Not Bleach.” Follow the care instructions on the product label for the best results.
