Setting Things Straight

Sun Mountain has optimized the level of features and technology that they can offer at a given weight.  Now, when buying a bag, a golfer knows the weight of the bag by its name.  And, they know that as they look at the 2.5 vs 3.5 vs 4.5 vs 5.5 the extent of features increases as the numbers go up.  Congrats to Sun Mountain for clarifying their product line.

While we prefer the 4.5 LS (reviewed  here) the Sun Mountain 3.5 LS has a ton of features at its weight.


The weight of the Sun Mountain 3.5 LS Stand Bag is 3.5 pounds including straps.

This weight is one of the lightest high-quality bags that we review.  As mentioned in our Buyer’s Guide there is a trade off between weight and features.  Generally, within a product line, the lower the weight the fewer the options.

Getting Clubs In and Out of the Bag

The Sun Mountain 3.5 LS Bag has a four-way top with full length dividers and a diameter of 9” which was expanded in 2019 to increase ease of getting clubs in and out of the bag.

The opening of the bag is appropriate for the weight and size of this bag. The top design easily accommodates putters with over-sized grips.

Ease of Carrying the Bag

The bag has the X Strap System with high-density foam designed to be wider at the shoulder for greater comfort.  The Strap System also features a strap guide to enable the two straps to easily interact with each other.   The 3.5 LS also has an “Air-Flow” cushioned hip pad. The bag has an integrated top handle, spine handle and bottom loop for easy lifting options.

Given the ultralight weight of the bag,  this bag is easy to carry for 18 holes.


The Sun Mountain 3.5 LS Bag has 7 pockets including:

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

In terms of other attachment points, the bag has a pen holder and towel loop.

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 roller bottom leg 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:

  • A matching rainhood
  • Nine color options
  • A comparatively compact profile


Sun Mountain’s suggested retail price is $234.99.

The $234.99 MSRP price tag is relatively high.  For the money you will get a high quality stand bag, with a great array of features,  at a very 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.
