BUNDLE HARD COVER + SLEEVE 5mm Neoprene Insulated Slip for 100 Gallon Oval Stock Tank Koozie

100 Gallon Stock Tank Insulated Cover + Neoprene Sleeve Bundle

The Polar Protector 100 Gallon Hard Cover + Neoprene Sleeve Bundle is the ultimate setup for keeping your stock tank colder, cleaner, and more efficient—combining top-down insulation with full-tank thermal protection.

This bundle pairs a rigid EPS insulated hard cover with a 5mm neoprene sleeve, helping reduce heat gain, block debris, and maintain consistent water temperatures for cold plunge, livestock, and outdoor use.

Why This Bundle Works Better

• Top + side insulation system for full temperature control
• Keeps water colder longer by reducing heat transfer from all directions
• Blocks debris and contamination to reduce maintenance
• Reduces evaporation and stabilizes water conditions
• Maximizes efficiency for ice baths and cold plunge setups

What You Get

• Hard Insulated Cover – EPS foam core traps cold air and blocks sunlight
• 5mm Neoprene Sleeve – wraps your tank to slow temperature loss and reduce exterior heat transfer

Built for Performance

The hard cover insulates from above while the neoprene sleeve insulates the sides—creating a more stable thermal environment inside your tank. This dual-layer system helps minimize temperature swings and keeps your water colder for longer compared to using a cover alone.

Ideal For

• Cold plunge and ice bath setups
• 100 gallon oval stock tanks
• Outdoor tanks exposed to sun and heat, or extreme cold
• Anyone looking to reduce ice usage and maintenance

Why Upgrade to the Bundle?

Using a cover alone protects your water from debris and sunlight—but adding a neoprene sleeve significantly improves insulation across the entire tank. This bundle is the best option for anyone serious about maintaining colder water with less effort and fewer temperature fluctuations.

Durable, Weather-Ready Construction

The neoprene sleeve is made from thick, flexible 5mm material (similar to a wetsuit or koozie) and includes a secure buckle and drawstring system for a snug fit. The hard cover features a rigid insulated core designed to withstand outdoor conditions, debris, and repeated use.

Fit & Compatibility

Designed for 100 gallon oval stock tanks. Always confirm your tank dimensions before ordering to ensure proper fit.

Frequently Asked Questions

Does this actually keep water colder than just a cover?
Yes. The sleeve insulates the sides while the hard cover insulates the top, reducing overall heat transfer and helping maintain colder temperatures longer.

Will this reduce how much ice I need?
In most cases, yes. By slowing temperature loss and heat gain, this setup can reduce how often you need to add ice.

Is the neoprene sleeve waterproof?
Yes. The neoprene material resists moisture and helps prevent condensation from affecting performance.

Is it difficult to install?
No. The sleeve is installed by sliding it over the tank and securing it with the buckle and drawstring system, while the hard cover simply sits on top.

Is this only for cold plunge use?
No. It’s also useful for livestock tanks and outdoor water storage where insulation and cleanliness matter.
