I have a few kleen kanteens and they've all been great. I use them all the time. I had the 27oz first and then bought the 40oz because I wanted the extra capacity. The 40oz is great for bringing in the car or if I'm going to be out all day, but I've been surprised to discover that I use the 27oz a lot more. Yes it holds less, but it a lot more convenient to carry around with me.

I have the XL and probably should have gone with a L. I fit two sleeping bags & sleeping pads, a tent and most of my camping & bike gear into this with space to spare. I would have packed more, but that would have put me over the 50lb per bag airline restriction. If there were wheels on the bag, I definitely would have used them, but the shoulder straps worked out fine. I haven't mastered the art of getting the packed XL bag onto my back gracefully yet, but once it was on, I was able to easily get around with it using the shoulder straps. Overall, the bag is big enough to let you bring piles of clothes and gear, but the fact that it doesn't have wheels and has to be carried around on your back, makes you reevaluate how much you really need to bring with you.

I haven't used the bag much yet, but so far it's held up some airline flights and being strapped to the roof of my car.

This was my first winter in UT and these skis were great in a variety of conditions this winter. I was surprised at how many people commented or asked about them, usually about the width, color ( they are bright) or just wanting to know the brand.
