Rated 5 out of 5 by from Great sun and rain hat I bought this hat for the Winnipeg Folk Festival. It kept the sun off and was water resistant during the rain. The tie worked in high winds and when boating. I'm very happy with my purchase. It is compact and folds for travel.

Rated 5 out of 5 by from My constant companion for almost 5 months This hat was fantastic! I would give it 10 stars if I could. It was my daily companion for 5 months through Asia. I wore it every day. It was great to protect from the sun or rain. The brim is wide enough to provide adequate coverage from the sun. The brim holds its shape even after I folded it to put in my rain jacket pocket. It also cleans very well. I got bird droppings (a huge amount) on it, and even after it was sitting in the sun for several hour hours before I could get back to the hotel for a proper washing, it came completely out. No trace left. I even put it in the washing machine and it came out fine. The brim also provides great coverage when it rains. I didn't need an umbrella as this kept the rain out of my face and freed my hands. The chin strap was essential for windy days and even the elastic band around the head was very useful for windy days. The only drawback was that it left a mark on my forehead which was only an issue if I wanted to take it off for a photo. The top is light enough so it doesn't feel hot on hot days. There is an internal cloth to help keep sweat away. It performed perfectly in a variety of situations. It packed well in my small pack. You won't regret this purchase!

Rated 3 out of 5 by from couldn't get it to stay on in the wind good coverage, but only when there wasnt' wind - it acts like a parachute with wind and wouldn't stay on, so did not work well while rowing a raft in a canyon.

Rated 4 out of 5 by from Like it a lot! The only knock against this product is that it doesn't breath as much as I would like.

Rated 5 out of 5 by from Worth replacing I first bought this hat 2 years ago in preparation for a multi-week walking trip. I wanted something stylish enough for city use but lightweight and shading enough to protect me from intense heat and sun. It minimizes my need to use sunscreen every time I leave home. I love the flattering shape of the brim, the sleek thin straps, and the neutral color. It was a great disappointment when I lost my hat recently, but after trying out all other viable options this hat still won my choice for a replacement.

Rated 5 out of 5 by from Goal Achieved The hat fits well (unlike my previous one - it bunched a bit), the band inside the rim does not itch my forehead (ditto), and looks flattering. The unsolicited compliment from my companion on the hike was a nice bonus.

Rated 1 out of 5 by from not satisfied Specs say brim is 5 inches wide. In reality, the front is 3 inches wide and the back is 4 inches wide. Very expensive hat, plus shipping. I immediately returned it.
