Product Customer Reviews

Product description said runs small, so I ordered next size up, shouldn't have. A little big on me but works fine. I use them under my lightweight waders, keep me nice an cozy.
I bought this on sale and better than what I expected
Awesome product that I picked up at a great price. They also wash and dry nicely. Use them whenever I need an extra layer in the cold.
Hi Ryan,
Thanks so much for sharing your experience with us.
See you Soon :)

I use these as part of a layering system and they have done a great job of keeping me warm and dry
Hi John,
Thank you for taking the time to write us a review! We are happy to hear that you like our men's ski base layer bottoms 500. It is a great product that will keep you warm and will, at the same time, allow your body to breath efficiently.
We hope to see you soon,
Kindly,

I was skeptical of fleece as a baselayer. But having tried merino wool, silk etc, this is the cheapest and most comfortable baselayer that I have tried. I bought 4 pairs I think.
Hello Steven,
We are glad to know that you are loving your ski base layers and they are the right fit for you. We hope to see you at the store again soon. Have a great day. :)

Very good design and quality. But next day I wanted to buy it again , M size sold out.
This fits well, keeps me warm without adding extra bulk.
Hello John!

See you soon at Decathlon Brossard!
Have a nice day,

Great price and great fit
Washes well and are v warm.
Excellent thermal pants,very comfortable and warm
Fab for playing sport outdoors. Keeps you warm and dry and easy to move in
Great general Base Layer to Keep Warm
Ideal worn below an outer layer and venting in the garment is great. A little more weight to them would make them great for very low temperatures - that's being really picky though as I always feel the cold.
Thank you for your review Anthony.
We really appreciate you taking the time to do this.

Lovely and warm. Not yet been used for any seriously strenuous activity, but the brushed lining traps the air so definitely at the warmer end of thermals. Superbly good value!

What type of fit is the men's bl ski 500 base layer?

What are the benefits of polyester?
Polyester is the most-used fiber for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibers can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet.It is limited in its ability to reduce odors.
