Simply zip it up, and you have a fully functional sleeping bag. The filling is made of imitation silk cotton, a lightweight, synthetic fibre that offers exceptional warmth retention. You'll experience a gentle, soft touch against your skin, promoting better and more restful sleep.
I highly recommend this Travel Bird blanket, poncho, pillow, and hammock liner.... boy that's a mouthful lol. In short this is an extremely versatile piece of gear that will instantly prove useful in a vast array of situations. This is especially helpful as it is something that can (and should) easily be kept in your vehicle, thus you have it on hand whenever you need it (like in an emergency situation in the winter). First off this makes a surprisingly comfortable pillow as the outside is a "crystal velvet" that is very soft and comfortable against one's skin. I was surprised that when folded up correctly you don't feel the plastic buckles as the pillow feels similar to a foam stuffed throw pillow. Once you unzip the pillow and unfold it, it becomes a very warm blanket similar to a woobie (a military poncho liner). Despite being thin and lightweight this is amazingly warm and comfortable as this utilizes a polyester fiber as its filling material. If you unzip the final portion of the pillow part it reveals a hood and can be utilized as a blanket poncho. This particular one stands out for this purpose as beyond the simple plastic buttons (one on each side) that make arm slots. If you utilize the buckle clips you can clip the back and front keeping the blanket out of the way as you move about. As a sleeping bag this is on the tight side but is plenty tall enough for a 6 foot 2 inch adult, and is a standard rectangular type. This is equipped with a double sided zipper that allows you to open the bottom or top accordingly. The only negative I have for this would be the hood hole, this is a real squeeze to fit my head through. Now I do still fit but this is something that could be made a little bigger in future models. In closing as I mentioned above, I highly recommend this piece of gear as beyond being super helpful for many basic situations this could be life saving in an emergency. I really appreciate you taking the time to read all of that, moreover I hope this uncovers any questions you may have had. I also hope you are currently having and continue to have an amazing day and get to enjoy some time outdoors, possibly well being wrapped up and comfortable with this fantastic blanket, pillow, sleeping bag ect.
