Rated 5 out of 5 by from Excellent comfort and warmth I bought these leg thermals and after one week I went back and bought another pair along with the top as well. They are the best thermals I've ever had. You can't beat Aussie Merino.

Rated 5 out of 5 by from Warm and Resilient! These are the best thermals I have owned. Always bought wool but they tend to get holes very quickly and in the bush are not very resilient. The core poly/wool blend is fantastic and pretty resilient. Not that you cannot put a hole in them if you run into a sharp object. The thermal properties are great. If you tend to warm up quickly they can be a bit warm on days above 10C, but below that with wind chill, fantastic!

Rated 1 out of 5 by from XXXL no longer big enough I used to swear by these and have bought them for several years. However, I purchased my usual size XXXL in 2020 and they no longer fit properly-far too small.

Hi what country are your thermal KMDAscents made in?

Asked by: Bruiser 59
Hi these are made in China.

Would these be good for working in a cool store environment for up to 50 minutes at a time @ 0.5 degrees c on a forklift, not much physical movement? Also, transitioning from 0.5c to ambient temperatures of 15 - 20c

Asked by: thebigmoa
Yes these would be suitable to help keep you warm. As always with varying conditions, the easiest way to combat is to layer up so that you have the option of going between temperatures while still being a comfortable temperature your self.
