My pair will be here today and I will report on how well they do. I ware glasses so heated goggles have been a game changer for me. I currently run a pair of 509 ignite aviators witch have been pretty good except for the clunky battery pack and dumb interface button. I'm excited to see how these work out!

 

you'll be impressed and those 509 ignites will be the backup pair. a warning though, glasses may not fit in them so you may have to get prescription inserts.

 

How are these powered? What's the power source?

I'm seeing these pop up with some Instagram brand ambassadors and I'm curious.

 

they have an internal battery pack that is not visible. they look like any other pair of non heated goggles so no clunky battery to get hung up or wires to break.

 

they also have a magnetic lens attachment system so changing lenses for different conditions takes seconds.

 

I have been using goggles for the past 15 years, never had a fogging issue since I started wearing the klim arctic balaclava, the only time I change up is below 10°F I also wear a lighter balaclava under the arctic. I have used lower end Klim goggles and a pair of 509's both performed the same.

 

So I received the goggles and I'm unhappy to say these wont work with glasses. Debating on returning them due to this. Also with the compact size the view area is small VS the 509 aviators
Gonna try the insert lenses if it is cost effective but Tempest should of made them bigger to comply glasses.

 

Well I made a pair of glasses work and they are very good. But both brands have pluses and minuses if you put the 509 field of view and size combined with the tempest battery would be perfect!
