Versatile piece, I feel like I can wear it with just about anything. Simple tank top, collared shirts or button-ups, sweatshirts and jackets.
I wear it all day without feeling uncomfortable and it's skin safe for me who has sensitive skin.
If I were to get into the nitty gritty, its very durable, the links are alternating open and closed links that aren't soldered, it's completely unnoticeable though and not an issue at all, that's what I expect of stainless steel really. It's definitely a casted piece from the look on the underside so I'm not worried about it breaking from being work hardened, and bumping it isn't gonna accrue stress like softer metals.
I travel lots as an engineer/developer/artist-in-residence so I choose to not own very much, but this piece will definitely stay with me wherever I go.
