I noticed an article in this months Trail Magazine on base layers. They featured an Xcelcius Megatherm top that claims to be certified down to -25c. I have had a look on their website and it looks to be good but can't find any reviews on here so don't know if it is a new brand.
Has anyone on here used this garment before and have any feedback or advice.
I am planning a trips later in the year to Snowdonia and trekking in Scotland when it will be very cold so this could be ideal.
Any advice would be great.
