Decathlon clothing, SH & MH numbers

[TrickyD]

Does anyone on here use Decathlon for winter clothing, or have any idea what the SH & MH numbers refer to ? I thought it may be to do with waterproofness (if there is such a word) but they are used in discription of other non clothing items. Just after a windproof and showerproof fleece.

I've been looking through some of the videos and the only connection to MH and SH l can make out is Mountain Hiking and Snow Hiking. If you are looking for a winter fleece go as high as possible in both MH and SH.
