Unless they specifically say they are for nylon, most of the heat press vinyls should work on polyester and poly blends... I did a sample run with Eco Film, Eco Film Plus, Videoflex, Videoflex Extra and Easy Weed. All stuck to 100% poly jackets after numerous hot water washes and high heat dryer runs.
In the end, I went with Elastoflex transfers from Ace Transfer since I was making over 200 jackets in 2 colors and the amount of time to cut, weed and register/position that many pieces was too much.
