Great sunscreen, but too pricey!
Size: 5 Fl Oz (Pack of 1)
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.

Super light and doesn't come off with sweat
Style: Tropical Coconut
Great stuff. Its super light, once the smell wears away you forget you every applied sunscreen. It also goes on super easily and doesn't leave my face super shiny.
To my surprise it also doesn't come off easily with sweat. I've used other brands and the moment you sweat it just all washes away.
Overall great stuff. The fragrance is a bit strong for me but I usually use unscented stuff so I'm extra sensitive to it. Good thing is the smell does wear away after a little bit.
