Truly a unique design- sleeves and chest made of sleek poly fabric where body transforms into a nylon mix that feels of rain jacket vibe. See.. very fashion forward!! Meant to be oversized, small bungee pull at bottom of each side adjust boxier cut. Note: pulls only gather material a small amount.. and yet, the actual neck opening is tight! Fits like a mock turtleneck.. just without the excess 1" of mock fabric! I've included pics of up close details- tags are tricky bc not in English!Mocha is a fantastic earthy brown hue- cut pairs with leggings, shorts, denim, khakis.. easy to dress up/down. No need to size up, this has plenty of room (less tightness in neck opening!) body + sleeves bring ample width and length. Ordered L for: 40+yr old, 5'2", 143lb, 38C.. medium would've fit better. Care: wash on cool + line dry. No ironing!!For $112- I'm unsure how much I love the look. As a bigger investment, I must be smitten and not sure I am. Personal choice for a totally unique design- well made with solid finishing detail. Hoping info can help you.. stay safe everyone.
