My wife loves this hat, she literally wore it every day last winter! It is thin enough that she can wear it under her bike helmet on cooler days, or as a liner under another hat when it is really cold out. This is the softest wool outerwear I have ever encountered, very few itches. If you're looking for lighter weight insulation for your head on fall or winter days, this is an excellent choice.

excellent lightweight hat!!
i bought this one just in case i lost the one i already have or in case they decide to change the style for some odd reason. i don't get cold too easily so i like the fact that this hat is lightweight and compact so i can keep it in my pocket just in case (hence the name "Pocket 200" whaddya know truth in advertising) the first one i bough and still have is now 2 or 3 years old and i LOVE the stupid thing!! it fits great under a ski helmet, another hat or just sitting out on your pointy pate! if you're one of those folk who get super cold really easily you might wanna step up to one of their 300 or 400 weight hats or move south. no matter what you can't go wrong with icebreaker! i would marry this company if i could!!! LoL

no more pulled or broken hair
My ski instructor recommended this to wear under my helmet. As his wife so correctly pointed out , it protects your top hair from being pulled or broken while skiing with a helmet. It also keeps your head nice and warm. Once again, my husband followed my lead with new icebreaker items and is wearing the same cap under his helmet , just because it feels comfortable. Even if you aren't allergic to polyester and many manmade fabrics as I am, Icebreaker wools are terrific.

great pocket sized hat
great little hat. purchased this for skiing but took it on my trip to India for when the weather got colder. you wouldn't figure India would be under 40F in November but it did and this keep me warm during those nights. the only bad thing is that it can get a little itchy on the forehead when you wear it for too long.

Another great Icebreaker product
For trekking, camping, fishing, hunting...this product won't disappoint. A great lightweight way to stay toasty in the outdoors.
