is there anyway to shrink i pillow withput tearing it apart?

Question

like is there any way to suck out the air so it can fit in my bag thx

Answer 1

There are special bags that have an exhaust but no air inlet. If you use one of those you just roll and as the air gets forced out the size shrinks.

If you can not get one of those, if you can find a plastic zipper bag big enough you can do it yourself, press the zipper nearly closed, roll the pillow, while still under pressure close the zipper all the way.
You can also roll the pillow and bind it with string, push it into a too small carrier-bag or roll it real tight in a towel, and roll that tight around the pillow, but this is all harder to do.
