These are great

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.

Surprisingly comfortable

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.

Great baselayer for your legs

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.

Warm, breathable

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?

The men’s base layer BL SKI 500 has a regular cut.It is a classic straight cut that adapts to all body shapes.

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.
