[GEARMENT] The "Pillowcase Compression Sack": How to shrink bulky winter jackets inside carry-ons without vacuum pumps

How do you pack a puffy winter jacket into a 20-inch carry-on without taking up half the suitcase?

Puffy down jackets trap vast amounts of ambient air, creating massive volume without much weight. Stuffing a puffy jacket tightly into a zippered travel pillowcase compresses trapped air and turns heavy outerwear into a neck pillow.

Step-by-Step Compression Protocol

1. Fold & Roll Jacket: Zip up your down jacket, fold arms inward, and roll it tightly from the hem up to the collar.

2. Stuff into Pillowcase: Insert the rolled jacket into a soft jersey or velvet travel pillowcase.

3. Zip & Compress: Kneel on the pillowcase to squeeze out trapped air and zip it tight. You now have a functional neck pillow for your flight that uses zero luggage space.

Target Audience: Winter travelers, budget airlines passengers, backpackers, and smart packers.
