I'm considering the purchase of a longsleeve purchase polo, it would be my first longsleeves polo.
I've seen the fitting on some tumblr and it's definitely what I would like.
I'm reading everywhere sunspel is very confortable, I can't wait to throw away my lacoste polo: are like a jail, even the italian fit version, those polo are out of style, I never had lacoste till 1 year ago but it's already enough for me.
Coming back to sunspel the unique thing I'm worring about is the recent quality of their production. As HRoi said, I also read they moved the production to Turkey even if doesn't appear on the label, it mean that they re producing there and putting the buttons in England. It wouldn't be a problem for me if are not produced in England if the quality would be the same, but I saw even some pictures and the new ones look very very cheap, fading after a couple of wash and so on.
By the way, I'd make a test buying some short sleeve polos first seeing now are on sale for 25/30 euros
