User Review: Therm-a-Rest Trekker Pillow Case
Price Paid: $10
So simple... Just take a super soft and cushy poly fabric, and turn into a pillow case, and vioila! Instant pillow when misc clothing is placed inside. Want a firmer pillow, just put a bit more inside. Want it softer, then pull something out.
The empty sack weighs next to nothing and is handy when moving stuff into and out of the tent, or as a stuff sack as well. Would've been an easy DIY project with the right fabric and a few minutes with a sewing machine.
I do wish it cost a bit less - but given the amount or use it gets, and the flexibility it affords, I'd have to say it's well worth it!
