We hand-make our Neoprene Insulator Sleeves in Jersey City. The material itself is custom fabricated for us and ensures long-lasting insulation. Similar types of Neoprene are used for deep-sea diving to keep divers safe and warm for long periods of time. The spongy fabric has an excellent stretch to it and is machine washable.
Neoprene Sleeves measure 9’X8” and have a Velcro closure. The spongy fabric has a good stretch and is machine washable. DO NOT MICROWAVE.
Each Insulator Sleeve is shipped with 2 Warmer Packs. The packs are filled with natural cherry pits. They are used to pre-heat your Insulator Sleeve and your Bentgo box. Heat the packs in your microwave, oven, or air fryer.
The sleeves are sized to hold many containers and boxes no larger than the below-listed measurements. They easily fit our highly insulated Warmables Lunch Bag.
BENTGO KID SNACK CONTAINER BOX 6x4x2"
BENTGO MICRO STEEL SNACK CONTAINER 6x4x2"
BENTGO MICRO STEEL LUNCH CONTAINER 6x4x2"
PRESERVE RECYCLED PLASTIC CONTAINER 7x6x2"
You can use any other container fitting the Sleeve. For best results use smaller, cube-like boxes and fill-up compartments versus spreading the food out in a larger box.
