I love COOLA products. They are a good substitute for my favorite sunscreens by Bare Republic - which was discontinued. Unfortunately COOLA products are very pricey. For that reason, I must use other brands where it makes sense. Trader Joe's spray sunscreen works very well and is $5.99. Coppertone Water Babies works for water sports. I'm saving my $28 COOLA lotion sunscreen for when I need a non greasy odor-free sunscreen, for example when I spend time in the sun followed by lunch out or shopping.

Would recommend this sunblock!

Size: 5 Fl Oz (Pack of 1)

Loved this sunblock for my stay abroad in the Caribbean. Left no white cast, and barely had any sunblock smell. Felt like a lotion if anything, and best of all, I didn't get burned! Would recommend.
