The Complete Guide to Bumkins Wet Bags: Sizes, Uses, and Which One to Buy

If you’ve started researching reusable wet bags for diapers, swimsuits, or messy clothes, you’ve probably noticed Bumkins offers several styles. The right choice depends on where you’re going and what you’re carrying. This guide breaks down the sizes, features, and real-world uses so you can pick the one that fits your routine.

We’ll cover the Wet Bag, Wet Dry Bag, Extra Large Wet Bag, Wet Dry Clutch, and Packing Cubes. Each has a different job, and yes, you might need more than one. Let’s sort out the differences.

Bumkins Wet Bag Sizes at a Glance

Bumkins makes wet bags in three main sizes: the standard Wet Bag (medium), the Extra Large Wet Bag, and the compact Wet/Dry Clutch. The standard Wet Bag is roughly the size of a large lunch tote and holds about 3-4 cloth diapers or a full outfit. The Extra Large Wet Bag is noticeably bigger — think diaper bag backpack or gym duffle — and can hold several outfits, a small blanket, or a week’s worth of swim gear. The Wet/Dry Clutch is slim and fits in a purse or diaper bag pocket, perfect for a single wet swimsuit or a few soiled cloth wipes.

There’s also the Wet Bag + Wet/Dry Clutch Set, which gives you both sizes in coordinating prints. If you’re trying to decide between a standard bag and a clutch, think about your daily load. For daycare drop-offs, the standard Wet Bag is the most versatile. For quick errands or pool trips, the clutch is enough.

• Standard Wet Bag: ~13 x 17 inches — holds 3-4 diapers or one outfit
• Extra Large Wet Bag: ~18 x 22 inches — holds multiple outfits or a small blanket
• Wet/Dry Clutch: ~10 x 12 inches — fits a single swimsuit or wipes

Wet Bag vs. Wet/Dry Bag: What’s the Difference?

A standard Bumkins Wet Bag is a single compartment with a waterproof lining and a zipper closure. It’s great for keeping wet or dirty items separate from the rest of your bag. The Wet Dry Bag, on the other hand, has two compartments: one waterproof side for wet items and one breathable side for dry items. This is especially handy when you need to carry a wet swimsuit and a dry change of clothes in the same bag without them touching.

If you’re packing for a day at the beach or a pool party, the Wet Dry Bag saves you from carrying two separate bags. But for everyday daycare use, a single-compartment Wet Bag is simpler and easier to toss into a larger bag. The trade-off is that you’ll need to pack wet and dry items separately.

• Use a Wet Bag for daycare, diaper changes, or separating soiled clothes.
• Use a Wet/Dry Bag for pool days, overnight trips, or gym bags.

Extra Large Wet Bag Uses: Beyond Diapers

The Extra Large Wet Bag is a workhorse for families who spend a lot of time on the go. It’s big enough to hold a full change of clothes for a toddler plus a parent’s shirt, or a wet towel and swimsuit after a lesson. Some parents use it as a portable laundry bag during travel, tossing dirty clothes in until they reach a washing machine. It also works as a wet bag for cloth diapers when you’re away from home for a full day.

Because it’s so roomy, the Extra Large Wet Bag can double as a packing cube for bulky items like jackets or blankets. Just keep in mind that it’s not structured — it’s a soft bag, so it won’t stand up on its own. If you need organization, pair it with a Packing Cube 2 Pack for smaller items like socks or underwear.

• Great for travel, sports, and long daycare days.
• Can replace a small laundry bag on trips.

Packing Cubes vs. Wet Bags: When to Use Each

Packing cubes and wet bags serve different purposes, but they can work together. Bumkins Packing Cubes (like the Packing Cube 2 Pack: Mickey & Friends Varsity) are lightweight, breathable organizers that keep clothes tidy inside a suitcase. They don’t have a waterproof lining, so they’re not meant for wet or dirty items. Wet bags, on the other hand, are fully waterproof and designed to contain moisture and odors.

If you’re packing for a family trip, use packing cubes for clean clothes and a wet bag for swimsuits, dirty laundry, or leaky toiletries. The cubes help you stay organized, while the wet bag keeps messes contained. For short trips, you might skip the packing cubes and just use a wet bag as a catch-all for damp items.

• Packing cubes: organize clean, dry clothes.
• Wet bags: contain wet, dirty, or smelly items.

Wet/Dry Clutch Review: Compact and Convenient

The Wet/Dry Clutch is the smallest of Bumkins’ wet bag options, but it punches above its weight. It features a zippered main compartment and a small exterior pocket, both lined with waterproof material. It’s slim enough to slip into a diaper bag, purse, or even a large pocket. The clutch is ideal for a single wet swimsuit, a few cloth wipes, or a small snack pouch that might leak.

One downside: because it’s compact, it won’t hold a full outfit or more than one diaper. If you’re heading to the pool with a toddler, you’ll likely need a larger bag as well. But for quick errands or as a backup, the Wet/Dry Clutch is a smart addition to your diaper bag. The Wet/Dry Clutch: Palm Daze is a popular print that adds a little fun to your daily carry.

• Best for: one swimsuit, cloth wipes, or a small snack pouch.
• Not ideal for: full outfit changes or multiple diapers.

Best Wet Bag for Daycare: What Parents Recommend

For daycare, the most common choice is the standard Bumkins Wet Bag. It’s big enough to hold a change of clothes, a couple of diapers, and a wet bib, yet small enough to fit in a daycare cubby. Many parents also appreciate the Wet Bag + Wet/Dry Clutch Set because the clutch can hold soiled cloth wipes or a small snack, while the larger bag handles clothes.

If your daycare requires labeled bags, the Wet Bag is easy to write on with a permanent marker. The Extra Large Wet Bag is overkill for most daycare setups unless your child is in a full-day program that includes swimming or outdoor play. Stick with the standard size for everyday use, and add a clutch for extra organization.

• Standard Wet Bag is the most versatile for daycare.
• Wet/Dry Clutch adds organization for small items.

Choosing the right Bumkins wet bag comes down to your daily routine. For daycare and everyday diaper changes, the standard Wet Bag is the reliable workhorse. For pool days or travel, the Wet/Dry Bag or Extra Large Wet Bag gives you more flexibility. And for quick trips, the Wet/Dry Clutch is a compact lifesaver. You don’t have to pick just one — many families keep a couple of sizes on hand for different situations.
