I've already bought two different colors, and it's only an extreme exercise in restraint that's preventing me from buying a third. i can wear it at work (it's that non-gear looking) or out on the weekend...it's very warm, but not so much so that it's oppressive for indoor wear. i probably won't use it as a technical layer, though...it seems a little bulky for that. i do think it runs a bit large (unlike most Mountain Hardwear gear)...i usually wear a small in most MH, but i got a better fit when i exchanged my small sarafin for an x-small. i have really sensitive skin and sometimes find this sweater a tad itchy, but it's nothing a light camisole doesn't solve. highly recommend the sarafin!
