I've been a big fan of the Pactimo gear for at least ten years. Their apparel is of superior quality and holds up to miles of cycling. My orders are always filled accurately and shipped promptly. My only disappointment with my most recent order is that I could not find any sizing information on the summer sleeves. I ordered two sizes for my husband (L and XL), hoping one of them will fit him. He's tall (6'2"), but doesn't have large biceps. He hasn't tried the summer sleeves on yet, but I am confident that I'll have no problems initiating a return or exchange to get the proper gear.
