Coffee/tea filter straw - The Guitar

I've been using this 20g filter straw for a while now. It might not be the lightest, but it's definitely a good'un. Two stage filtering via the series of holes in the tube and the spring sleeve that tensions the end cap.

Easy to clean, has never clogged with either the coarse or fine dusty yerba varieties. Would work great for those who still use ground coffee.
Works as a regular straw if you push the end cap to the side.

Bought mine from Uru-Shop

There's other variants, of which I've not tried. I have used the traditional bombillas and they can clog and aren't as easy to clean.
