I use one of the newer lightweight Capilene base layers and have for years used their Cap 4/Thermal weight/other name as both a base layer in cold weather and a mid-layer in warmer weather.
When I looked up the Mid-Weight layer I thought it was a typo 4.4 oz/yard 6.7 oz for the crew; the Thermal weight 3.4 oz/yard 5.2 oz for the crew
the Lightweight is you would expect- lightweight 2.3 oz/ crew weighs 3.5 oz
all are grid patterns
that doesn’t really jive????
