Lululemon Slouchy Sling Bag 6L vs. 13L: Which size is right for you?

The Lululemon Slouchy Sling Bag 6L and its larger counterpart, the 13L version, mainly differ in capacity and organization. The 6L is a compact bag designed for carrying just the essentials, making it ideal for minimalists and quick trips, while the 13L offers more than double the space, catering to commutes, longer outings, or gym sessions where you need to pack extra items like a tablet or light jacket.

Here's everything you need to know to choose the right Lululemon sling bag for your lifestyle.

Slouchy Sling Bag 6L vs. 13L Comparison

Size & Capacity

The most obvious difference lies in their size. The 6L bag has a 12" x 8" x 3" footprint and is designed for the absolute essentials: phone, keys, wallet, maybe some lip balm and sunglasses. It is decidedly minimalist and will not hold a standard water bottle or a tablet.

The 13L bag, measuring 15" x 10" x 4", provides considerably more space. This is the bag you choose if you want to carry essentials *plus* other items. It can comfortably hold a tablet (like an iPad), a water bottle, a small notebook, a portable charger, and even a light jacket or change of clothes for the gym. The extra capacity makes it far more functional for a full day out.

Features & Organization

While both bags share a similar aesthetic, their organizational capabilities differ. The 6L keeps it simple with a main compartment, a small front zip pocket, and a couple of internal slots. It’s built for grab-and-go ease, not for meticulous organization.

The 13L version is designed for those who carry more and need to keep it tidy. It features more internal and external pockets, allowing you to separate your tech, personal items, and snacks. This makes it much easier to find what you're looking for without digging through a single large compartment, making it a better choice for commuting or travel.

Price & Value

There's a notable price difference between the two. The 6L is priced at $78, making it a more accessible accessory for shoppers who want Lululemon quality in a compact package. Its value comes from its frequent, everyday use for quick trips.

At $128, the 13L represents a bigger investment. However, its value lies in its versatility. It can serve multiple roles - a daily commuter bag, a gym bag, a personal item for flights - potentially replacing several other bags. If you need the extra space, the higher price is justified by its enhanced functionality.

Comfort & Usability

Both bags feature an adjustable strap for a custom fit, allowing them to be worn over the shoulder or across the body. Due to its featherlight 0.5-pound weight, the 6L is incredibly comfortable and easy to forget you're wearing it. It never feels cumbersome, even when full.

The 13L bag is slightly heavier at 0.8 pounds and will naturally weigh more once packed. However, Lululemon’s ergonomic strap design helps distribute the weight evenly, keeping it comfortable. You will feel its presence more than the 6L, but it's far more manageable than a traditional backpack or tote for carrying a similar amount of gear.

Which One Should You Choose?

Both sling bags are excellent choices, but they are built for different daily needs and lifestyles.

Choose the 6L if:

• You are a true minimalist and carry only your phone, wallet, and keys.
• You need a lightweight, hands-free bag for quick errands, dog walks, or festivals.
• You are primarily looking for a stylish, compact accessory rather than a utility bag.
• You have a smaller budget but still want a high-quality Lululemon bag.

Choose the 13L if:

• You need a bag for your daily commute that can hold a tablet, charger, and a water bottle.
• You want a versatile option that works for the gym, weekend outings, and as a personal travel item.
• You prefer having extra space so you're never caught without what you need.
• You are willing to invest more for greater capacity and organizational features.

Frequently Asked Questions

What's the main difference between the 6L and 13L Slouchy Sling Bags?

The main difference is capacity. The 6L bag is a compact option designed for essentials only, while the 13L bag offers more than double the space for items like a tablet, water bottle, or a light jacket, making it far more versatile for longer days.

Can the 13L bag fit a laptop?

The 13L bag is designed to hold a small tablet, but it will not fit most standard-sized laptops. Its slouchy design and dimensions (15" x 10") are not structured to securely accommodate a device larger than an iPad or similar tablet.

Are the bags waterproof?

They are water-resistant, not fully waterproof. The technical fabric will repel light rain and splashes, keeping your belongings dry in a drizzle, but it's not designed to be submerged or withstand a heavy downpour.

Which size is better for the gym?

The 13L size is better for the gym, as it can comfortably fit a change of clothes (like a shirt and shorts), a small towel, and your personal items. The 6L is too small for carrying workout apparel.

How is the Slouchy Sling Bag meant to be worn?

It's designed to be worn across your body (either on your chest or back) or slung over one shoulder. The adjustable strap allows you to customize the fit for maximum comfort.

Is the 6L bag big enough for a water bottle?

No, the 6L bag is too compact to fit a standard water bottle along with other essentials. If carrying a water bottle is a priority, you should opt for the 13L version.

Are both bags comfortable to wear when full?

Yes, both are designed for comfort. The 6L is so lightweight it's barely noticeable. While the 13L is heavier, its wide, ergonomic strap helps distribute weight evenly to prevent it from digging into your shoulder.

Do they come in the same colors?

Generally, yes. Lululemon typically releases its core colors (like black and other neutrals) across both sizes and introduces seasonal colors for both, but availability can vary. It's always best to check the website for current options.
