The Sun Mountain 4.5 LS, on the other hand, comes in at 4.5 pounds and is designed to strike a balance between a walking bag and a cart bag. 

While the 4.5 LS is still relatively lightweight, the extra weight allows for additional features and storage options.

Storage and Pocket Layout

Both bags offer plenty of storage options, but the 4.5 LS has more pockets and a better layout for cart use. 

The 4.5 LS has a cart strap pass-through that keeps the bag secure without blocking the side pockets. 

One user on Reddit mentioned that the 3.5 is not designed for cart use, while the 4.5 adapts seamlessly for both walking and riding, offering a waterproof valuables pocket and plenty of storage.

Comfort and Straps

When it comes to comfort and strap design, both bags have their own advantages. 

The Sun Mountain 3.5 LS features a more cushioned hip pad, thicker straps, and several additional pockets due to its slightly heavier weight. 

The straps on the 3.5 are said to be comfortable and are designed for easy carrying on the course.


The Sun Mountain 3.5 LS Stand Bag is lighter compared to the 4.5 LS, weighing approximately 3.8 pounds, including straps. 

On the other hand, the 4.5 LS weighs 4.5 pounds, making it slightly heavier but still manageable for both walking and riding. 

If weight is a significant factor for you, the 3.5 LS is a better choice, as it is lighter and easier to carry.

Club Organization

The 4.5 LS Stand Bag features a 14-way top, making it ideal for organizing your clubs and allowing easy access to them. 

In contrast, the 3.5 LS Stand Bag has a smaller number of dividers, though the exact number is not specified in the search results. 

If club organization is a priority, the 4.5 LS with its 14-way top would be the superior option.

Storage and Pocket Configuration

The 4.5 LS offers more storage space, including a waterproof valuables pocket. The 3.5 LS, while lighter, has fewer pockets and storage options due to its lighter design. 

However, some users mentioned that the 3.5 LS has better pocket layouts and straps compared to the 2.5 LS. 

Depending on your storage needs, you may prefer the 4.5 LS for more storage options or the 3.5 LS for better pocket layouts.

Cart Compatibility

The Sun Mountain 4.5 LS is designed to be compatible with both walking and riding, easily adapting to carts when needed. 

The 3.5 LS, on the other hand, is primarily designed for carrying and may not be as seamlessly compatible with carts. If you frequently use a cart, the 4.5 LS would be a more suitable choice.

They use durable fabrics and advanced manufacturing processes to ensure the longevity of the bags.
