Ultralight backpacking t shirt - Outdoor Research Echo Long Sleeve Tee - Women's

I really like this shirt for backpacking. It's constructed comfortably for movement and wearing a pack. And it's ultra light. In addition, I really like the Outdoor Research clothing for all around good fit. Only downside is that they do wear out quickly, being of such light fabric. I don't mind as I'm going for as low pack weight as possible. That's the only reason I don't give it 5 stars. It's got great coverage for sun too.
