While this is called a Travel Sling, most of the guys we've talked to use it at home, too. Forget muscle control or holding up your legs; just lay back and let the fun happen.
This Neoprene Travel Sling weighs less than a pound and folds down easily to fit in your luggage. Because it's made of neoprene, it's comfortable to wear and has a bit of give to it. The bottom either puts on the shoulder straps first and then, while on his back, puts his knees through (as is shown in the photo where the model is on his back), or he can step through the leg straps first so they hold the back of his thighs (shown in the photo where the model is sitting).
Care Instructions: Machine wash cold, gentle cycle. Hang to dry. No dryer, no bleach, and no iron.
