Pit Viper The Heater Flip-Offs 2.0 Sunglasses

These are awesome. The flip-up is smooth and they fit great. I bought them for cycling and they stay put. Love the design.

The lens is great and the flip-up actually works. They’re a little tight on my big head, but they’re comfortable enough. I got the XL.

I use these for mountain biking and they are incredible. The grip is amazing and they never fog up. The flip-up is handy for climbing. The lenses are tough - I've wiped them on my shirt and no scratches. They come with two sizes which is great. Totally worth it.

They're okay. The flip-up mechanism feels a bit gimmicky, and the nose pad gets uncomfortable after a while. But they look cool.

Just got my Flip-Offs and they're awesome. The hinge is super smooth and the arms don't slip. I've gotten so many compliments. They're my new go-to for running and hanging out. Get them.

The fit was odd and they pinched my temples. Also, the flip-up isn't as useful as I thought. Wouldn't buy again.

For $50 these are a steal. The build quality feels premium, and the included two sizes is a nice touch. I just wish they came with a case.

These are the best Pit Vipers yet. The improved grip keeps them from sliding off when I sweat. The flip-up is smooth and locks in place. Two sizes in the box is perfect for sharing. 10/10.

They're sturdy, but a bit heavier than my other pair. The flip-up mechanism adds weight. Still good performance and style.
