Just like what the description says. This package is meant to warm you core.
In California we always need to have layers. One minute it can be 75deg and the next minute 55. A long sleeve T made from excellent fabric is a must for a base. A Sherpa Hoodie will keep you warm all the way down to freezing temperatures.
Specify whether you would like a grey or beige T and select the size that works best for you.
All this and a great value at the package price.
Brave the Elements!
