Mydays ATV Rear Storage Bags: Tame the Trail Without Leaving Gear Behind

Introduction

Every ATV rider knows the frustration: you’ve got a day of trail riding planned, but your gear—tools, snacks, extra layers, recovery straps—has nowhere to go. The factory rack is bare, and strapping a loose duffel bag to the back is a recipe for lost equipment and scratched paint. Without proper storage, you either leave essentials behind or risk them bouncing off on the first rough stretch.

The solution is a dedicated ATV rear storage bag designed to handle the bumps, mud, and weather of off-road use. In this guide, we’ll walk you through what to look for in a rear rack cargo bag, then examine two strong options from Mydays—one purpose-built for ATVs and another versatile bag that works for boat owners who also ride.

What to Look for in an ATV Rear Storage Bag

Choosing the right bag means matching your riding style, machine, and typical cargo. Here are the key evaluation criteria to keep in mind.

1. Universal Fit and Mounting System

Not all ATVs have the same rack dimensions or shape. A good universal bag should include adjustable straps, buckles, or hook-and-loop attachments that work with most rear racks. Look for compatibility with common brands like Polaris, Honda, Can-Am, and others—but always check your specific model’s rack layout before buying.

2. Weather Resistance

Trail conditions change fast. Rain, mud puddles, and creek crossings can soak unprotected gear. A bag with water-resistant fabric, sealed seams, or a rain cover keeps your belongings dry. At minimum, the material should shed light moisture and dry quickly.

3. Capacity and Compartments

Think about what you carry most often. A single large compartment is fine for bulky items like a jacket or tool roll, but multiple pockets help organize smaller essentials—phone, map, multitool, first-aid kit. Consider whether the bag expands or has external attachment points for extra gear.

4. Durability and Material

ATV bags take abuse: UV exposure, abrasion from branches, and constant vibration. Look for heavy-duty fabric (often polyester or nylon with a PVC coating), reinforced stitching at stress points, and corrosion-resistant hardware. A bag that frays or tears after a few rides isn’t a bargain at any price.

5. Ease of Installation and Removal

You don’t want to fight with straps and buckles every time you load up. Quick-release buckles, tool-free mounting, and clear instructions make a big difference. Some bags also detach easily so you can carry them like a duffel when you reach camp.

6. Security and Anti-Theft Features

If you leave your ATV parked on the trail or at a staging area, a bag that locks to the rack or has zipper loops for a padlock adds peace of mind. Even simple features like covered zippers can discourage opportunistic theft.

7. Value for the Price

A good storage bag is an investment in convenience. The price should reflect the build quality, capacity, and features. Compare what you get for the cost—not just the lowest price, but the best balance of durability and function for your typical rides.

Mydays T-Top Storage Bag (Boat Life Jacket Storage)

Pitch: While designed primarily for boats, this large T-top storage bag is a versatile option for ATV riders who need serious capacity for bulky items like life jackets, camping gear, or soft-sided coolers.

Who it’s for: Riders who also own a boat, or anyone who needs a large, weather-resistant bag that can be strapped to an ATV rack for carrying bulky, lightweight gear. It’s especially useful if you frequently transport life jackets or similar soft items.

Features: This bag is designed to hold 4 to 6 Type II life jackets, making it a spacious storage solution.

Buying Tips

1. Measure Your Rack Before You Buy

Even “universal” bags have limits. Measure the length and width of your ATV’s rear rack, and compare it to the bag’s dimensions (listed on the product page). A bag that overhangs too much can snag on branches or interfere with your taillight.

2. Prioritize Water Resistance Over Waterproofing

Fully waterproof bags are often expensive and heavy. For most trail riding, a water-resistant bag with a rain cover or sealed zippers is sufficient. If you ride in heavy rain or cross deep water frequently, consider adding a dry bag inside for sensitive electronics.

3. Think About How You Access Gear

Do you need to open the bag while riding? Some bags have side pockets or top-loading designs that let you grab items without dismounting. If you frequently stop to grab a map or snack, choose a bag with easy-access pockets.

4. Check Strap Quality and Attachment Points

Thin nylon straps can fray or snap under load. Look for wide, reinforced straps with metal or heavy-duty plastic buckles. D-rings or webbing loops on the bag also let you lash extra gear like a sleeping bag or tent.

5. Consider Multi-Use Value

If you also own a boat, truck, or SUV, a bag that works across vehicles gives you more for your money. The Mydays T-Top bag, for example, can serve as boat storage, ATV cargo, or even a gear bag for camping.

FAQ

Q: Will the Mydays ATV Rear Storage Bag fit my Polaris Sportsman?

A: Yes, the bag is designed as a universal fit compatible with most ATVs, including Polaris Sportsman models. Always double-check your rack dimensions against the product listing to ensure a proper fit.

Q: Is the T-Top Storage Bag waterproof?

A: The bag is built with marine-grade materials that handle moisture well, but it is not fully submersible. It will protect your gear from rain and splashes, but prolonged exposure to heavy rain may eventually allow moisture through.

Q: Can I use the ATV storage bag on a Can-Am or Kawasaki?

A: Yes, the bag lists compatibility with Can-Am, Kawasaki, Arctic Cat, CFMOTO, and other major ATV brands. The adjustable mounting system should work with most standard rear racks.

Q: Which bag is better for carrying tools and heavy items?

A: The ATV Rear Storage Bag is better suited for tools and heavier gear because it’s designed specifically for ATV racks and includes multiple compartments for organization. The T-Top bag is better for bulky, lightweight items like life jackets or sleeping bags.

Final Recommendation

For most ATV riders, the Mydays ATV Rear Storage Bag is the clear choice. It’s purpose-built for rear racks, fits a wide range of machines, and offers good organization at a fair price. The 5.0-star rating from early buyers suggests it delivers on its promises, though the small sample size means you should check recent reviews for long-term feedback.

If you need to carry bulky, lightweight gear—or you also own a boat—the Mydays T-Top Storage Bag is a versatile alternative. Its large capacity and marine-grade construction make it a smart addition for riders who want one bag that works in multiple settings.

Either way, you’ll keep your gear secure and organized, letting you focus on the trail ahead.
