Question: Is the brim stiff?
Document: I've owned 2 Tiley hats for over 20 years and have worn them in Alaska and around the U.S, Asia, Central America, and S America, fly fishing, hiking, backpacking, canoeing, and I wear it at home almost daily. Tilley replaced the first because it fell apart, and the second just fell apart after washing it after coming back from the Amazon, Machu Piccu and the Galapagos---too bad because it was getting &#34;salty looking&#34;.The hats are comfortable, protect me from sun and rain, and the brim is stiff enough that the wind doesn't push it up when it starts to blow, and the straps keep it secure on your head when it really starts blowing.
This hat is very high quality. The workmanship that went into making this hat is exceptional. There really is no comparison to other boonie type hats. It holds it's form very nicely. It is stiff enough to hold its shape, yet very comfortable to wear. For the extra you pay for this hat you will find it to be well worth it! In my opinion you won't find a better boonie style hat!
This hat has it all...durability, coverage, style and practicality. Wearing it the right way (loose) takes some getting used to, but it's a quick adjustment. The T3 is worth every penny, so if you value the actual *function* of wide-brim hats in all conditions, buck up and dont settle for imitators. I've made that mistake before, but now that I have a Tilley, I won't make it again.
My partner has had his Tillley's for approx the last 27 years & will not wear any other hat. He has worn them to work, fishing, cruising, traveling in & out of the country, hiking,gardening, mowing the grass, you name it. So many times when we are away other people will comment on his Tilley. His favorite was the natural with the natural color under brim but since that is not available anymore he has adjusted to the green. Everyone knows Jayson & we are convinced it is because of  his Tilley.
I bought this hat after a friend from Greece showed me her husbands. She said it was the best hat ever.I bought this for Fathers day for my husband , he says its the best fit and light weight and a great feel to . The fit was perfect 7 3/8. The brim slops down just enough to protect his face from the sun. On a personal note from his wife he looks rugged and handsome at the same time. On a scale 1-10 it's a 10!!!!!!
The BEST hat I ever owned. The full brim of the hat is great protection from the sun. I wear it in the water no problem getting it wet. Well made hat the material that is use will stand up to a lot of abuse. There is no problem rolling up the hat sticking it in a backpack or suitcase and when you take it out it still looks great and holds it shape. One of the best features is the pocket inside the top of the hat. LOVE IT!!!! !
A wrinkled brim can be easily ironed.The manufacturer recommends for a proper fit that one should be able to insert two fingers (flat) between the forehead and the inside rim to avoid pressure (indentation mark) on the forehead. In a breeze, the windcord keeps the hat in place; I can attest to that.Tilley's attention to detail and quality merchandise, are equal to my all-time favorite purveyors of superb (safari/outback) clothing, Willis & Geiger, which unfortunately are no longer available.
Then I received a Gift card and decided to go for it. Money well spent. If anything happens to this one I won't hesitate to buy another. I've worn it for a month now and its just getting broken in. I wear it for gardening, yard work and general loafing about. (I'm retired so I do a fair amount of loafing about). I was in the rain today so I can say it's a good all weather hat.When I removed it from the shipping box it was a bit squashed and the brim was out of shape.
*** Update: This is now April 2012 I have been wearing this hat for almost four years now and I still like it a lot. I've washed it in the clothes washer many times now and that works real well. It'll come out all out of shape but ironing the brim flat on an ironing board then stuffing the crown with a towel rolled up till it's shaped then let it dry works well. When dry stretch over your knee till it fits good and your ready to go. Other than a couple stains that won't come out its still in excellent condition.
I hang the hat from a clip on the outside of my pack when I'm not wearing it and it's crushable and can be stuffed inside a pack or suitcase.I used the sizing chart to get the right size.I like a brimmed hat to protect me from the sun.The hats are great the only reason I down rated it to a 4 was because I ordered kahki with an olive under brim and got a solid khaki hat. I wanted to use the hat ASAP and didn't bother to return it. It's still a great hat.I highly recommend this hat.
