Sigg water bottle, $5, thaLowdown
I can't believe I'm sending you to a site that seems targeted toward skateboarders bent on spending all their allowance, and then some, on not-so-needful things. But, here I am, suggesting you spend $6 plus shipping for a Sigg bottle whose picture I can't even show you (it is NOT the one in the photo, here, although it's the same size and general idea).
The bottle's image doesn't seem to be available anywhere, but the bottle is from the Fall Progressive Line, 2005, and it's beige, and .6 liters (the size of the one here). I found a couple of photos of beige Sigg bottles, and many of them seem quite girly. One has pink polka dots. So bear that in mind. But you won't find a deal like this again -- the bottles go for $19 in most stores -- and you can always cover it with stickers.
I just bought two. Hurry, the deal ends this evening.
