Book bag strap pad.

I’m talking about the pads you see on straps on bag like this one. It can have padding for comfort and/or rubber to prevent slippage.

What do you call this, and where could you buy it (online or otherwise)? Thanks.

I Googled “shoulder strap pad” and found plenty of links, including one at Amazon.

Look at luggage and backpacking stores.

Thanks much, got it all squared away.
