Was looking for a summer weight long sleeve top and this fitted the bill - I’m a size 8 and originally ordered a M - had to swap for S but no hassles doing this exchange.
I have a few different styles of the io undies, but these are my go-to boxers. As a style, they're slightly longer in the leg which suits me, especially under long pants (They can be a bit too long under shorter shorts), they have all the benefits of the super soft io merino fabric that i love, but that extra crotch panel does exactly what it's supposed to, and makes these way more durable - so much better value. I know different people have different body shapes and will wear out clothes in different ways/places, but these are perfect for me and a real step up from the standard ones.
I bought this t-shirt for my husband. It is light weight and dries very quickly, which is great for hiking.
I bought these for my husband, who is about to hike the Camino. He loves them! They wear, wash and dry really well.
