Pearl Izumi Women's Aurora Thermal Top - Insulated Cycling & Running Base Layer for Cold Weather - Perfect for Winter Sports & Outdoor Activities

The yellow color is nice and bright. Material is very warm for winter sports. For sizing, I usually wear XS or S in a lot of clothing lines, but I ordered a medium because reviews said Pearl Izumi run very small. I could have went with a small and it would have fit great. Just so you know.The top has a nicely brushed interior for softness and extra warmth, which worked well for a run in the high-20s to low-30s. I would prefer a slimmer cut, though. The loose fabric in the armpit area chafed my underarms, something that doesn't happen with tighter-fitting running tops. I wore the top on a 15-mile run when the chafing happened, but I also wore it on a shorter 4-mile run before that and experienced no discomfort. I am petite build so this problem might be unique to me.Great style and look. Consider sizing up. I usually take a medium in Pearl Izumi but need a large in this top. Koo Bikes UK was easy to deal with in returning this item. Definitely a seller to use.I really like this top. It is super comfortable, looks great on and is perfectly functional and sexy too. I have worn it running, cycling and just out and about. It was a great purchase.I bought this top for my girlfriend who's starting to run and she loved it and fits perfect!!! Great product, I mean it's a Pearl Izumi, great brand!!Color a little bit too brightI bought this as a gift and it was a hit. Form fitting, stylish, and warm.
