I never liked the idea of using those blankets and pillows they passed out on airplanes, but traveling with my own took up my entire carry-on bag. Travelrest has a 4-in-1 Travel Blanket that fits into your carry-on without filling it up. Use the 4-in-1 Travel Blanket as a head, neck, or lumbar pillow while it’s packed away in its carry bag. Open it up, and it’s a poncho-style fleece blanket that covers you from shoulders to ankles. It won’t slip off, and it leaves your arms free to use those gadgets that keep you entertained during long flights. The 4-in-1 Travel Blanket is $24.95. It’s available at Travelrest or Amazon.com.
