Sealed Port Protection

Sand and grit in a charging port are hard to get out once they settle.

Wet-Hand Grip Texture

Wet or sweaty hands slip straight off the smooth glass of a bare phone.

Scratch-Resistant Shell

Rock, rope, and a pack full of gear scuff anything soft within a day.

Clip-On Attachment Point

A carabiner loop keeps a phone or tag attached instead of loose in a bag.

Cold Weather Flexibility

Plastic that stiffens near freezing cracks instead of absorbing a knock.
