Elann Peruvian Sierra Aran?

Has anybody used Elann Peruvian Sierra Aran? http://www.elann.com/productdisp.asp?NAME=elann.com+Peruvian+Sierra+Aran&Season=&Company=&Cat=ALLY&ProductType=5&OrderBy=+Order+By+ShortFibre&Count=107

I’m wondering about how it holds up (pilling etc.). I want to use it for a vest for my dad but I’d rather go with something more expensive if it means the vest is going to look good longer.

Thanks for any opinions!
