What Has Changed for the Sun Mountain 3.5 LS Stand Bag for 2023?

Sun Mountain likes to update its products every year. 2023 is no different. The most significant changes to the 2023 Sun Mountain 3.5 LS Stand Bag are:

  • A new cart strap pass-through has been added, located behind the full-length apparel pocket.  This makes it possible to strap the bag onto a cart without blocking its pockets
  • An extended hip comfort pad
  • Slight reorientation of two of the bag’s pockets
  • Return to 9 pockets versus the 10 in the 2022 model. (LOL, when a bag gets above 7-8 pockets, I lose count)

Some changes to color schemes have also occurred, but the overall look remains in line with prior models.


The Sun Mountain 3.5 LS Stand Bag weighs 3.8 pounds, including straps.  Compared with the Sun Mountain 2.5+, the extra pound allows thicker straps, a more cushioned hip pad, and several additional pockets.

This weight is among the lightest of the high-quality, full-service carry bags we review.  As mentioned in our Buyer’s Guide, there is a tradeoff between weight and features.  Generally, the lower the weight, the fewer the features and options.    

Getting Clubs In and Out of the Bag Sun Mountain 2023 3.5LS Golf Stand Bag Stand Top

The Sun Mountain 3.5 LS Bag has a nine-inch, four-way top with full-length dividers.

The bag’s opening is appropriate for the weight and size of this bag. The hidden benefit of having fewer dividers is that the dividers take up a lot of space and can interfere with getting clubs in and out of the bag. The top design easily accommodates putters with oversized grips.

Ease of Carrying the Bag

Sun Mountain 2023 3.5LS Golf Stand Bag Stand StrapsSun Mountain has standardized the strap system across its Light Series Stand Bag product line.  All of the LS Bags have the EZ Lite Dual Strap System, which has the following:

  • Thick, high-density padding, contoured to be wider at the top for greater shoulder comfort
  • Straps that can be adjusted in terms of length at all four connection points to the bag’s body
  • An innovative sliding mechanism that allows the rear strap to move along a connection rail at the center core as the golfer moves

We like this system because of the adjustability of the straps’ length and the rear strap’s potential dynamic movement.  These features enable a more customized fit.

Beyond the strap system, the 3.5 LS also has an “Air-Flow” cushioned hip pad to further enhance comfort in walking the course. The hip pad was extended in size for 2023.

The bag has an integrated top handle, spine handle, and bottom loop for easy lifting options.

Given the upgraded strap system, padding, and lightweight, the 3.5 LS is easy to carry for 18 holes.


The 2023 Sun Mountain 3.5 LS Bag now has nine exterior and interior pockets, including:

  • Full-length apparel pocket
  • A velour-lined and water-resistant valuables pocket
  • Hydration pouch positioned for easy access
  • Range finder pocket
  • Multiple accessory pockets

Regarding other attachment points, the bag has an umbrella holder and towel ring.

The bag has our preferred number of pockets with ample storage and specialization.

Stability of the Bag

The Sun Mountain 3.5 LS features a top-mounted, patented bottom-release mechanism with high-strength carbon fiber legs.

The bag offers the leg mechanism features of a high-quality, stable stand bag.


The Sun Mountain 3.5 LS Bag has the following:

  • A matching rain hood
  • Eight color options in 2023
  • The 2023 model year does offer a left-handed configuration in black.  This option is very rare!
  • A comparatively compact profile


Sun Mountain’s manufacturer’s suggested retail price for the 2023 model is $269.99. The 2023 model is significantly discounted on Amazon at the moment, potentially to clear stock for the 2024 model.

For the money, you will get a high-quality stand bag with a great array of features at a low weight.

  1. I am looking to join a league this year and I am looking to buy a new bag. Based on your review on the Sun Mountain Three 5 it looks like this bag holds up to the other big name companies products. I had previously not heard of this brand but I am now looking to give it a shot! Thanks!

    1. John, thanks for your comment. I can understand why you might not have heard of Sun Mountain. But, they are actually one of the big names in bags. The are just not quite as visible because they don’t make clubs or balls.

      In terms of the bag you are looking at, you can’t go wrong with the Sun Mountain Three 5. It’s light and easy to carry. And it comes in 12 colors so its super easy to find a look that fits your style.

    1. The difference between the 3.5 LS and the 3.5 LS ZG is that the ZG or Zero-Gravity has an additional hip belt that is designed to transfer the majority of a bag’s weight from a golfer’s shoulders to the hips. While I applaud the innovation, I personally like to keep things simple. Strapping an additional belt on to walk between shots is not something that I would do very often. Maybe if I really bombed a drive I would bother with the strap but other than that, I wouldn’t take the time to use the belt. One last thought, if I had a history of shoulder or back issues (but still wanted to walk) I might try it out.
