"Light and packable for minimalist fast hikes" Our Ultra light S.I. Sleeping Mat is for ultra-light hikers who can't go past the tried and true self-inflating foam mats. The 2.6 R-value provides the insulation needed through the shoulder seasons while the memory foam means you don't have to exert yourself inflating your mat at the end of the day. The only mat in our S.I. range to come in an extra-small size, it's easily fits into your ultra-light pack. All of our S.I. mats use the first ever, multi-function single valve designed specifically for self-inflating mats. No more fighting re-inflation as you try to roll up your mat!

Keeps great time
This is actually prettier than I thought it would be and I am tough on everything I wear. Never know what the day will entail, so when I clean it at the end of the day, it’s pretty shine comes right back. I’m pleased with it.

Very hard to see the HANDS, but pretty
Very pretty and I didn't have to remove links. Hard to see the hands unless you angle it in the light. I'm not sure if I'll keep it. I'll give it some time ..lol and see how it goes before Amazon's 30 day policy.

just makes it around my large wrist - but very pretty
If you also have a large wrist like I do, well ... try it out. Bought it to look delicate and pretty at my son's wedding, to match color of gown. Which it does. Side note: the hands are cobalt blue, for some reason! But you'd have to look up close to discover that. It doesn't take away from the overall look I wanted. Edit: !@#$@! - it BROKE halfway through the wedding! During the dancing, I discovered it on the floor. Downgrading this to one star, of course.

DIdn't Work
When I got the watch, it wasn't running, so I took it to a local jewelry store and had the battery replaced, which cost another $20+ and it still wouldn't run.
