My wife got me a 3-pack of the Adidas masks. To date, they are my favorite masks. I only go to the grocery store about once every 10-14 days, and I'm usually done in 50-60 minutes. But even an hour in the Adidas mask is very warm. I just think that's the nature of any mask. That being said, it is a vast improvement over my prior mask, which made me want to pass out after 30 minutes.
Overall, the mask itself is great. It goes up to where my glasses sit on my nose, fully covers the under the chin, and is snug.
I also did a pre-order of the Under Armour mask. It arrives the end of August. It's supposed to be better than all the masks in the linked article above. I'll report back once I have one. The first run of the Under Armour masks sold out in about an hour (this was in May or June).
