Adventurer's Hat

This battered, wide brimmed hat has an interior space considerably larger than its outside dimensions, roughly 6 inches in diameter at the mouth and 4 inches deep. The hat can hold up to 50 pounds, not exceeding a volume of 8 cubic feet. The hat weighs 1 pound, regardless of its contents. Retrieving an item from the hat requires two free hands and an action.

If the hat is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane. If the hat is turned inside out, its contents spill forth, unharmed, but the hat must be put right before it can be used again. Breathing creatures inside the hat can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.

Placing an adventurer's hat inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened. 

In addition, the hat can be used as a component pouch.
