REI Co-op - Flash Air 2

Get him a tent. A real one. https://www.rei.com/product/216300

Looks like a reasonable tent. I have one of similar design from REI. Even with a lot of mesh and flexibility with how you can set up the vestibule "wings" having a single wall above your face while sleeping invites condensation. Bring a small towel.

I have the Flash Air2 from 2021ish.

I've got a Coleman Hooligan with a bathtub floor. It's had no issues with NC downpours. Had rivers flowing under it with no moisture inside. Of course over got an REI Flash Air that's also handled those monsoons with no issues and that is just a standard floor. Like others have said, you have quality enough tents that this shouldn't be an issue. However a bathtub floor never hurts

Depending what you’re using it for! Do you go camping with your car? Or do you do backcountry hiking? If you’re gonna be carrying your tent you want to go for as lightweight as possible. Ounces really add up. I have an rei brand two person tent that’s super light and still spacious enough for two. If you won’t be carrying it on your back, you can go for more space, maybe a more heavy duty rain cover depending on your most common terrain. I would also find a tent that has its own footprint that can attach to the bottom. Saves on time and space when setting up. :)
