Eddie Bauer Men's Guide Midweight Baselayer 1/2-Zip. This is a really nice, mid-weight base layer. Originally size L but it shrunk a bit in the wash so now wears more like a medium. See measurements and pictures. Like new! Worn only a few times before it shrunk and now the sleeves are too short for me. I have long arms so it should fit a medium well. Approximate measurements (see pictures for locations and exact figures) Shoulder to shoulder: 16” Pit to pit: 18” Length: 27” Sleeve (shoulder to hem): 23.5”
