My legs are comfortable and toasty

I definitely wouldn't recommend wearing these when the weather is above 0. They're almost *too* good imccold weather, and they're so comfortable that I almost forgot that I was wearing them.

Under Length.

Great bottoms but the leg length is short and in winter if you are 6' plus you will need socks pulled up.

Never mind ski wear

Bought as thermal leggings for cold weather and watching my grandson play football on Saturdays and Sundays. Warm as toast.

Good extra layer

I've been buying these for years. Wear them on astronomy outings underneath trousers and around the house to reduce need for heating. Comfortable and keep me toasty.

Very, very nice

Additional Product Information


Main fabric: 100.0% Polyester

What type of fit is the bl 100 ski base layer?

The BL 100 thermal base layer 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 fibre for base garments because it is relatively inexpensive and offers excellent performance in various respects, and especially because the fibres can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet.
