It is a relief to have this on sunny days. I couldn't seem to keep my chest from burning even with SPF 70 sunscreen on. I hesitated at first because i thought it would be annoying and hot but it's not that bad. I can wear it fairly comfortably even on 95 degree days and it works perfectly to keep the sun off my chest. Like other reviewers have mentioned the knot at the back is the main issue I have and the reason for the 4 rather than 5 stars. I wish they would use a series of snaps instead so you could adjust it to different lengths and not have to deal with a chunky knot at the back of your neck. A design flaw for sure. But still better than burning. Wish it came in more colors!
