I want a better knee pillow. I need you to help me think of what i can use.
Requirements:
- Ultralight weight for backpackers.
- Big. As big as a regular bedroom pillow.
- Can't just be clothes in a stuffsack. (UL backpackers don't have this much clothing and my jacket is already in use.).
What i'm thinking is to use a plastic bag and blow it up like a balloon, then close it shut with a twist/clip/tie/clamp/knot/thing. A plastic bag is light, small, and blows up big. I can put the bag inside a tougher stuff sack for rigidity.
If so, what sort of plastic bag can i use for this? I need something airtight, durable-ish, and roughly pillow sized.
Thoughts?
Thanks for your feedback.
