Based on other reviews, i sized up to a medium, and it fits perfectly. The m is several inches larger than the old m's i've bought. It fits well and has 20” sleeves.

Shirt is lightweight, durable, and very well made. The shirt is very, very roomy. It does a good job of preventing sunburn.

The last one i got has a run in the fabric at the neck. The material is 100 percent polyester. It sticks to my skin like my hands after working in the garden for 10h without gloves (rough, unpleasant, slight sandpaper feeling) not comfortable.

Ordered in may 2021 by november 2021 had to throw in trash. It is mislabeled in size. The company needs to redo the size chart. Why do womens sizes have to be so ridiculously tiny?
