I have not looked for a specific travel case, but unless you are being really rough with it I would say a padded envelope or a generic small case would do it. It's pretty sturdy. I take it to to the office sometimes and just put it in one of the pockets of my laptop case. Also, for extra protection against scratches I never removed the clear plastic film that comes over the screen. Except for the red ""pull here"" tab, you can't tell it's there. 

My son loves these binoculars! Easy to use and amazing quality for the price! 

I don't know the exact size but it even fits 12-13 year old kids. 

This type of spotting telescope is easier to operate, and can focus quickly with one hand. 

It can resist light water, but it cannot be used for a long time in heavy rain or soaked in water.
