SHERPA 100% MERINO THERMALS
UNDERSTANDING WHAT YOU ARE BUYING
Merino wool is measured in gsm (grams per square metre). A thicker garment will generally keep you warmer. Sherpa uses a 240gsm weight. Other brands use 160-195gsm.
The merino wool fibre is measured in Microns, which is the thickness of the fibre. Wool that has a Micron from 19.5 or above is considered rough and will cause itchiness. Sherpa uses an 18.5 micron which is superfine meaning it is non-itch and very comfortable against the skin
