LIGHTWEIGHT SYNTHETIC FILL DESIGNED TO EXCEL IN ALL CONDITIONS

With technical fabrics and construction, 100% recycled, super-warm insulation, and tons of comfort features, these comfortable sleeping bags are designed to be lightweight enough for backpacking but cozy enough you'll want them in the campground too. The streamlined silhouette and Flow™ construction increase the thermal efficiency keeping you warm from head to toe. The Flex Pad Sleeve unites easily with your pad, and as you change positions over the course of the night, will keep you from rolling off your pad.

It is really well made and perfect for travel!
It is just like the picture and it is lovely. Plenty of room and under the tray it is large enough for changes with pendents. It is perfect for a girl and will be perfect for the amount of jewerly you take when traveling. Thank You!

Very nice little box.
This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.

Pretty
Very nice simple jewelry box. My only issue is spacing to put necklaces is a bit tight, but there is plenty of room in this little guy. I put a lighter next to it, for size comparison.
