100 Gallon Rubbermaid 5mm Neoprene Insulated Slip for 100 Gallon Oval Stock Tank

100 Gallon Stock Tank Insulated Neoprene Sleeve (5mm)

The Polar Protector 100 Gallon Stock Tank Insulated Neoprene Sleeve is designed to wrap your tank in sidewall insulation to help maintain colder water longer, reduce heat transfer, and improve overall temperature stability in outdoor conditions.

Made from thick 5mm neoprene, this sleeve is a practical upgrade for cold plunge setups, ice baths, and outdoor stock tanks where efficiency matters. It helps slow temperature loss in cold conditions and reduce heat gain in warmer weather, all while giving your tank a cleaner, more finished look.

Key Benefits

• Helps keep water colder longer by reducing heat transfer through the sides of the tank
• Improves temperature stability in changing outdoor conditions
• May reduce ice usage by slowing heat gain
• Waterproof neoprene construction helps keep the exterior dry and protected
• Secure fit design with built-in handles, buckle, and drawstring

Designed for Cold Plunge Efficiency

This 100 gallon insulated sleeve works by adding a thermal barrier around the sides of your stock tank, where a significant amount of heat transfer can happen. By insulating the tank walls, it helps your water stay more consistent over time and supports a more efficient cold plunge setup.

Built for Everyday Outdoor Use

Made from durable 5mm neoprene, this sleeve is built to handle repeated use in outdoor environments. The material is tough, flexible, and waterproof, helping protect your tank while standing up to weather, wind, and day-to-day wear.

Thoughtful Fit & Access Features

This sleeve is custom designed for a 100 gallon oval plastic foam stock tank and includes side handles, a buckle-tightening system, and a drawstring for a snug fit. It also features an insulated flap and access hole for the stock tank drain, and the neoprene can be trimmed if needed to accommodate plumbing or other modifications.

Ideal For

• 100 gallon oval plastic stock tanks
• Cold plunge and ice bath setups
• Outdoor tanks exposed to sun, wind, and temperature swings
• Anyone looking to improve insulation without replacing their tank

Neoprene Sleeve vs. Cover

This sleeve insulates the sides of your tank. It does not replace a top cover. For the best performance, pair it with a hard insulated cover or soft cover to help protect the top of the tank from debris, evaporation, and additional heat transfer.

Easy Installation

Installation is simple: turn your stock tank upside down, slide the sleeve over it, and pull it down into place. Then secure it using the buckle and drawstring system for a tight, stable fit.

Fit & Compatibility

Designed for 100 gallon oval plastic foam stock tanks. Approximate sleeve dimensions are 20 inches tall, 23 inches wide, and 39 inches long. Always confirm your tank dimensions before ordering.
