A built-in screen protector maintains responsive touch and Face ID functionality. Washable with soap or EPA-approved disinfectants, it’s ideal for diving, hiking, or daily use, delivering crystal-clear audio and photo quality.

" This Catalyst phone case is the BEST! My phone took beautiful photos through the case - both underwater and above water - the case kept my phone bone dry. "

" I can wash off my phone a bunch of times a day and not worry about if it’s alcohol sanitizer, germicidal wipes, or surgical scrub soap. "

" Case is very well made and seals perfect. I can even use it on my gimbal. The Lidar works great too. Had a drop onto hard tiles. Not even a mark. Works in the pool too. Worth every penny. 👍 "

" I have 3 boys and the case I got needed to be the best. I have dropped my phone multiple times over the past 6 months I have had this case and it’s held up great. Not a scratch on my phone! "

" This is the best case I have ever had; it is worth the purchase if you want to keep your phone away from water. "
