A basic hat, transformed.
SNPSLV™ (pronounced "snap sleeve") is a soft, moisture-wicking sleeve that snaps onto the adjustable back strap of any snapback. It turns the one uncomfortable, plain part of your cap into the most comfortable, and the most personal.

Why it exists
The hard plastic adjuster on a snapback digs into your head, traps sweat, and never matches your fit. We thought the back of your hat deserved better, so we made a sleeve that's ultra-soft, moisture-wicking, and fully customizable. No tools, no permanent changes. Snap on, snap off.
- Universal fit, works with virtually every snapback
- Soft against your head, drier through every wear
- Personalize with names, numbers, teams, or logos
Three seconds to better.
Snap in

Adjust
The strap still snaps and sizes exactly like before, now wrapped in soft, breathable fabric.
Stand out
Rep your name, team, or colors on the back of any cap you already own.
