Several packs include adjustable straps or firm fastener closures and are shaped to stay in place, providing a secure, hands-free fit during use.

Fill materials include gel fills and proprietary blends (examples list bentonite clay with food‑grade propylene glycol or medical‑grade gel beads).

The roll‑on lists spearmint, peppermint, and lavender essential oils.
