Stuffa A vest that replaces your suitcase

Initially developed to dodge excess baggage charges, this faux-down-filled puffer is essentially a wearable carry-on thanks to the 12 large pockets concealed within its lining, which're capable of holding up to 11lbs of clothing -- they suggest "4 socks, 4 pants, 4 tees, some gloves, a scarf, and a pair of jeans" -- all "without looking bulky or feeling uncomfortable", unlike you if the TSA takes you into a "private room".
