This white Capilene Cool Daily T-shirt offers excellent breathability and a comfortable fit. - Brand: patagonia - Model Name: Capilene Cool Daily - Size: M - Color: White Thank you for viewing. I purchased this last summer on a flea market site. There is a stain on the right chest that did not come out after washing (see photo 4). As indicated on the tag, this is a Spring 2024 product. I used it about 3 times for summer hiking. For reference, my height is 179cm, weight is 67kg, and I have a slender, muscular build. Capilene sizes S-M fit me best. I recommend size M if you prefer a looser fit (this item is size M). Patagonia sizing can be tricky, so please use this as a reference.
