A cap for the cap that’s already on the bottle.

Snaps over Rinse, Drip, Pour, Mist, or Wash. Locks the utility head against accidental opening so the bottle survives a backpack, diaper bag, or beach tote.

Designed for utility

The accessory that protects the rest.

  • Diaper bag spillproofing
  • Backpack and gym bag transit
  • Beach tote and pool bag protection
  • Glove box and trunk storage
  • Tackle box and tool kit organization
  • Camp dry bag and panniers

How it works

Snap on. Toss in the bag.

1

Pick the cap to protect

Seal fits over Rinse, Drip, Pour, Mist, and Wash. Same outer profile across the line.

2

Snap on Seal

The cover locks in place and seals the nozzle against pressure or accidental opening.

3

Pack the bottle

The bottle goes in the bag with the rest of the gear. No leak, no surprise.

Parents, travelers, commuters, campers

The cheapest cap protects the rest of the kit.

A utility cap is great until it pops open in a bag. Seal is the answer to that exact problem. It costs less than the cap it protects, fits the whole line, and lives in the same pouch as the cap it covers.

Two caps in the pack so the same Rinse bottle can stay sealed in the bag while a Mist or Wash bottle is in use, then swap the Seal over to whichever needs to travel.
