Durability through and through! Our Long Traditional Hammock Pillow's two sheets of all-weather fabric, lockstitched with heavy thread and corner grommets for added stability, sandwich a center of equally nonabsorbent recycled polyester hollowfill fiber. The fabric itself is solution-dyed, so the handsome blue glacier color is uncommonly fade-resistant. All of our outdoor fabric is likewise resistant to staining, rot, mold and mildew, and holds up to intense wear. Of course, our Long Traditional Hammock Pillow would hardly be our most popular hammock accessory if all it had going for it was heightened durability -- an uncomfortable pillow that lasts and lasts is hardly something to get relaxed about! This cushiony pillow is firm enough to offer real head support, while its exceptionally durable fabric is also genuinely as soft as cotton.
