It seems so thin. Is it OK to wear it when the temperature goes below -20F?

No way. It's more for fall and mild winter days. Perhaps 20 above with slight breeze.

-20F is very cold. That said, I have worn it as a sweater in +10F in the wind and with another longer winter coat over it I was very warm. A lot depends on wind chill, hat and gloves.

I did worn it and seem fitting fine.. It did little warm and loose fitted fine.. No problem with it. I am glad I worn it for my bicycle safety.

The material is thick and not very breathable. I would not recomend on hot climates, as baby is close to skin and your own body temp might make it too hot.

I haven't worn mine in the summer, but I think it would definitely be too hot. It's not like a regular underarmour shirt, it has a little extra insulation to keep you warm. If you're looking for a longsleeved workout shirt, I think Underarmour makes HeatGear that is specifically designed to be worn in warm weather.

I would say that if you take it off for a little while around every 20 minutes of use and let your arms cool down, it should not be a problem. With that said, it is probably more dependent on whether or not you are using it in an air conditioned area, or the temperature in the location you are in. I personally have not found heat to be of any real issue while wearing them.

Hi and yes - I wear this while running and am very comfortable when doing so. Colder than 45 degrees, I wear this over a dri fit long sleeve shirt over a tee shirt. A few miles into the run, I may have to unzip a bit (when weather closer to 45) and if it warms up, I've taken off and tied around my waist to complete my run - it's very light and lends itself to this well. It's been a great buy for me.

It's thin but that equates to greater ability to move, especially in the shoulders. I wore it in 68 degree open water and was quite comfy. The following year it was a bit warmer and chose to go without for more freedom of movement.

I think it may be too warm for you...depending upon the coolness of your bedroom. If we have the windows open on 50 degree nights, this comforter is not too warm! Hope this helps.

We are using it in the pool for the first few weeks of swim team. Our outdoor pool just opened, and our practices start next week, and I'm expecting it to still be to chilly to swim without something like this :) I just plan to make sure to rinse it after every practice.If you are asking if it will be too warm in the summer, I'm not sure about that. It would be warmer than just a regular swim suit.

I wear it all day and it seems to go well. My experience tells me that as long as you don't wear it over sleeping, it should be fine.

yes! Its very cool and light to wear since its made with very thin material. Plus the fan doesn't let it heat up (if you live on a tropical island like me this would be an issue).

Its light enough to backpack in, however, I wouldn't use this under 35 degrees.

The coat is great for cool weather sports, and it breaths pretty well, so I'd say it would be good for running, although in cooler weather--probably not great for warmer weather. The coat has a very snug fit so if that works okay for running then it should be fine. It should be fine for just about any activity from about 37º or so up to about 65º.

I can say I was comfortable in this jacket with a long-sleeved t-shirt on underneath while boarding in a high of -2 F (not factoring in the wind chill I was making going down the slopes). I probably wouldn't count on it for too much lower than that, but it is surprisingly warm for how thin and light it is.

I only wore mine once cuz it wasn't warm enough. maybe you should contact the seller.

No it will not be uncomfortable. Just unzip the sides. If you don't plan to use it in temps below 50 degrees why don't you buy one that is not rated as low as this one.

Yes! I live in Minnesota and I wore this this winter with brutal -20 degree temps. Its amazingly light and warm!!
