I agree with ~gd!!  I have a few pieces of clothing that are 100% bamboo and the more I wear and wash them the softer and nicer they are to wear!  I've had the oldest hoodie for about 3 years(at least this is the third summer I can find pic of me wearing it) and other than a couple of spots( what can I say.. I am a messy person I have to hide good clothing from myself almost to keep it spot free). The ones I have are thinner long sleeved hooded t-shirt style from a local casino.  They are warm enuf to wear in the winter but in the summer they keep you quite cool too.  they seem very well suited to the hot and humid we have in Michigan.  I wore one of them out fishing even tho it was hot due to a bit of sunburn.  it shielded me from the sun but didn't seem to cook me much.  I hope everyone finds a piece of bamboo clothing to try. I would like more but got these for free and can not afford to buy them out right yet.
 Who does their math?  No really?  who!!!!)  and since I am the clothes pins worst enemy I set a resolve for myself I got a Nail apron free from the lumbar yard and put all my clothes pins in there and don't ever ever leave them on the line any more and open to the elements.  I was going thru wooden ones every year(I'm sure I would have gotten more mileage from them if I had taken them in like I do the bamboo) I have had them for quite a while now and just love the bamboo clothing pins.   they stay firm and stiff even after a few years. and yes I have had them get wet during quick pop up storms where we missed the laundry in the rush to get stuff tied or stowed.  They dried out and don't seem to really have any rot on them.    I did find one in the yard under the lines this spring. must have been dropped and missed.  it is dirty colored now more of a gray than the nice yellow but still seems sturdy and it still works..  I'm thinking about leaving just that one out there to see how it fares in the harsh weather.
