You asked.

Why would I upgrade to Apollo II instead of Apollo?

AnswerYou’re getting more protection without going bigger. Better drop resistance, antimicrobial lining, and a key ring so it’s easier to carry.
Is this fully waterproof?

No. It handles rain, splashes, and drops near water. It floats, which helps. But underwater is not its job.
What’s the antimicrobial lining actually doing?

It helps keep the inside cleaner over time. Less buildup from sweat, dirt, and wherever your phone’s been.
Does it float with a phone inside?

Yes. That’s the point. If it hits water, you’ve got time to grab it instead of watching it disappear.

Phoozy Apollo II Capsule

"I am so happy with this product! I keep my phone in my car a lot and I have destroyed the batteries on a couple phones due to overheating. With the Apollo II Capsule I can leave my phone in my car all day and my phone does not overheat!"

Great find

"it was 103 degrees here in Denver, CO and my iPhone did not overheat and I am grateful to have my phoozy hanging on my side. It pretty much stayed the same temperature. Thank you"

Love it!

"I bought this in time to go to the lake for July 4th and used it the entire time. Worked great in the sunshine and the heat. I think I convinced a few others to buy one also."

Great product!

"After skiing on a very cold day and having my phone in my coat pocket, I found my phone dead at the end of the day due to the cold. I needed to use the phone but now had to wait till I could get it warm enough to work again. I purchased this product and can’t be happier! I don’t have to worry about a dead phone due to cold……..never again! As a ski instructor/race coach it’s a must and has influenced my fellow instructors to purchase. Highly recommend this to any outdoor enthusiasts for all seasons. The only thing to consider is if you have a phone case the is thick it might be difficult to side in and out. I purchased size large case for my IPhone 14pro max with a case on it."

"Excellent product"

— Edgar G. (5/5)

"This was too small for my Pixel 6 with the case on although I actually ordered a size bigger than they suggested. (It said to order a medium) It is super snug and I have to desperately pull to get it out of the case!"

— Lisa (2/5)

I've been using my Phoozy

"I've been using my Phoozy computer travel case for years, so I know their quality is great. Bought the phone case to protect it from this crazy heat.`"
