Question: Do all of these hats have an Insect Shield?  One retailer sells one that specifies that, but for a higher price.
Document: Everything about the hat is so well thought through, it will last for years. There are certainly less expensive hats that look similar but the Tilley is by far the best, and superior quality is always worth the price.
I was a bit apprehensive about spending so much for a Tilley. BUT, I also bought some cheaper hats.I can only tell you is that the inexpensive hats are back at the places that I purchase them from. The features, fit and quality of the Tilley make it worth the price.
I purchased hats for my wife and myself. At first we thought the price was a little high but we had heard so much about them that we had to see for ourselves. After hiking almost 7 hours in windy, then rainy, then sunny conditions, we found this hat well worth the price. The rim is large enough to protect from the sun. It is light and comfortable so you don't realize you have a hat on. The vent keeps your head cool.
Since we meet a friend that was using it and shared his experience we were thinking about getting one. Price was a factor but at the end my wife decided to choose it as a birthday present. Thanks!
I did actually experience this once when we were out hiking, but besides that I got many compliments in general.I don't regret purchasing a Tilley one bit and I would highly recommend it to anyone looking for an amazingly comfortable, resilient, and stylish headpiece. Don't let the price turn you away. This hat is well worth it.
GREAT HAT! Fits for all sizes and what a comfortable hat. Have gotten many comments on my Tilley and all were possitive! Even had two gentleman ask where they could purchase this hat! I told them and one remarked "that will be my next hat." Can't go wrong with Tilley! Amazon got it to me quick and at a good price too!Love My Tilley!
We had done research re. Quality and price. Obviously Amazon had the best price and gave us prompt delivery as always. My husband just loves his hat and it really looks good great on him! He has worn it for almost 3 weeks on our recent trip overseas, it never felt too hot, it held up beautifully even after the first "machine wash" - it is just a great hat, great quality an all around great product. Hurry and get one for yourself!
There's nothing like a Tilley (floats, hidden pocket, string tie easily hidden when not in use). I bought my first Tilley (LTM0) from the company website, but my second one thru Amazon because of much better price and free shipping. I was planning to buy another LTM0, but saw Amazon reviews that liked the LTM6 more (less floppy, better retention of shape). They're both great, but I do like this one (LTM6) more.
Just read about the hats and go ahead and spend the money. You won't need another one for a very long time.
What I wore in other hats was a 71/2 this one is a 75/8.Good luck and use.Jim
