Yes, that is a good one, and I recommend it. Check the sizes so you don't get one bigger than you need.
But in a pinch or big hurry just use the cheap one from WM, they function the same though noisier and a bit harder to work with. Keeps you just as warm ( and for me:dry) though.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
