Gear Talk - What's cool for the summer?

Hi everyone!
So this is my first post here. Still trying to figure it all out. Being a big gadgets lover, I hope I can inspire some of you with some cool gear every now and then. Let me know if you like me to continue, or stop bothering you..
Anyways, with summer and holidays in mind I came across this snorkeling mask. It's especially great for people who are struggling with the typical snorkel (you know, the one that you need to stick into your mouth). But this seems extremely cool to me: You can breath under water just like you do in normal life...either through your nose or through your mouth. And it even gives you a 180 degree view!
I just found out that there seems to be a version available with a GoPro mount. Or maybe you can attach it on to it. I'm not exactly sure. Anyways, if you're interested in one then don't just order it online. Seems that the best price can be found in an actual Decathlon store. Prices online are way too high. I'm just saying..
