Are they really as versatile as they claim? They look like they might be a neat solution to cope with Oregon's ever changing weather.

How is the sizing? My head is on the smallish size for an adult and the pattern that I really want is only available in juniors. They say juniors is for heads 19" and 22" and the originals are for 21" and 25". If I'm measuring correctly I'm about 22.3". I would think with as stretchy as they claim to be it would be okay, but don't want to push my luck. Do you think I can still squeeze into the junior comfortably?

The "headover" is a longer version of the buff that can be doubled over for neck-warming or using single-thickness pulled up as an ear warmer or balaclava. One size fits all and it is one of the best value and most versatile bits of kit for cycling. I always wear one in cold weather.

I use one every day for 9-10 months of the year. I love them.
About the size, I would guess that the "original" would be better, but perhaps that is just because I don't like to have my buff's too tight fitting.

They sell them at the REI in Portland. You could try one on.

I use one in the summer, as I have to keep my ears covered when I ride. It works well. I've got the one made with the coolmax fabric. In the winter, I use these flaps that velcro onto my helmet straps.

what is a buff

a bandana I believe unless they are refering to somthing else

Buff- stretchy, seamless tube of synthetic fabric. multipurpose head and neck gear.

not really warm enough as a hat when its cold, but Buff's are a great neck warmer/wind blocker/ nose and face warmer.

Nice as a helmet liner if it isn't very cold, but not much warmer than a cotton cycling cap. better as a neck thingie.

I've been using mine quite often for cycling. I can use it folded over 2-3 times as a head band/hat thing under my helmet, as a neck warmer, as a balaclava, etc. I find it works quite well, but it's too thin for really cold weather.

It doesn't seem that a buff would work very well for the head for cycling. Too much material to deal with under the helmet. But as a neck gaitor it would be very useful.

I think it's better to utilize the helmet as an insulator since it's already there. To do that in the cold all you need is a helmet cover and a thin scull cap.

Or I also use a freeride bike helmet in winter which has less ventilation holes and comes down in the back. Very warm with thin scull cap underneath even without a cover.

If you happen to ride without a helmet in winter a multi layered buff wrapped around the head and ears with the top open to breath may work well. But then you haven't got the protection of the helmet.

However, if you are a woman with very thick long hair it may be a good method of head covering. Very popular among woman skiers.

Not true, in my experience. The material is very thin and fits as nicely under a helmet as a bandana. My buff is my #1 favorite article of winter clothing.

Morning commute: I use it over my chin and mouth if it's really cold. On the way home when it's warmer I ditch my turtle fur skull cap and and use it on my head. I also use it what I ski.
