Time to give seamless base layers another try. Seamless construction promises stretch and comfort, but most base layers on the market have a nylon and Lycra® mix that feels comfortable when you put it on but then ends up feeling wet when you're actually riding, and you freeze when you stop. We've worked hard to make this Core Seamless base layer keep you warm and dry, thanks to the addition of polypropylene and polyester yarns, while not compromising the stretch comfort of seamless. We think we've found the sweet spot that also provides a nice level of warmth for cool to cold days.

Great sunscreen!
Size: 6.7 Fl Oz (Pack of 1)
We have used this sunscreen lotion on multiple beach vacations, and most recently on our cruise. The quality, coverage and protection are great. The lotion glides on smoothly and is not sticky. It has a light fresh scent that did not irritate the members of the family with sensitive skin. This is one of our favorite lotions to use, and we keep repurchasing it. The price point is great as well.

It works
Size: 6.7 Fl Oz (Pack of 1)
Well this product works. At first I thought maybe the Caribbean sun wasn’t as bad as people said since I was in the sun for 4 days wearing this sunscreen and hardly had tan lines, then I tested my theory for 1 day with another brand and got a sunburn. I took star off (would really only do a half if it allowed) for when you go in the water or if you sweat there is a bit of white residue that it leaves. But for sun purposes, if you want protection, I highly recommend.
