PowerLayer Men's & Boy's Compression Base Layer Top Long Sleeve Thermal Underlayer - Mock Neck

I bought two of these compression shirts to see how they compared to the current market leaders in the U.S. like Nike and Under Armour. They seem to have the same compression fit and are warm. Great for under a fleece. Will update as winter settles in because I'm curious to see if they're truly warm enough for New England winters. Also, they come from the U.K. via Royal Mail. So, it took about 18 days to arrive. Don't purchase if you're in a hurry.

We have purchased Under Armour fleece base layer in the past and have always been happy. We tried this spur of the moment because it was a Prime option. Unfortunately it is very thin. If you are looking to just keep arms covered when it's a bit cool it's a fine option but if you are looking for warmth this really isn't the best option. The quality is good for the price as a base layer but in no way is it thermal.

Ordered a large because I'm actually a medium. Too tight to the point where it was hard to breath. Really have to fix your sizing. I understand what base-layer compression is but this is too tight.

My husband loves it and it fits as expected. Since this comes from the UK, expect the shipping/delivery to take extra time. Product is certainly worth the wait.

Fit is excellent. Color purchased is black and seems to be rubbing off on white clothing. Recommend wash before use.

My son loves these shirts. He has worn them as layer shirts for years. He wore one of these almost every other day for four years. We just bought two in the next size. The shirt holds its shape after thousands of washes.

Great item. Exactly what I thought it would be. Great material, Great feel. I highly recommend one. I may end up getting another or 2.

This is a great product. It fits as described and is very comfortable. If you don't want to spend what cold weather Under Armour costs, this could be a great alternative. Even though it comes from abroad, it arrived very quickly.
