It's very light and fairly comfortable. It will dry quickly when crossing small water or just a shower. When wet the lining can hold some water how long depends on the temp, but just take it off and wring it out if cool. I find it works from 55degrees F and up when hiking. I have not worn it since last Sep, but will go back when down Florida next month.

I am split on lightweight backpacking. I carry the kitchen/1st Aid/purifier for my group and any weight savings is great. My mantra is "Ti is my friend"
