Sun Mountain has optimized the level of features and technology that they can offer at a given weight. Now, when buying a Sun Mountain bag, a golfer knows the approximate weight of the bag by its name.
And, since golfers know that there tends to be a tradeoff between weight and features, golfers 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.
Other than color combinations, there are no significant differences between the 2019 and 2020 3.5 LS model years. The specs are the same. So, as you read below, the description is the same for both years. We tend to be frugal shoppers, so we prefer the 2019 model due to price.
One last thing, while we love the 3.5 LS for its lighter weight, are favorite Sun Mountain stand bag is the 4.5 LS (reviewed here).
Sun Mountain understands that the big trade-off in carry bags is the weight of the bag versus the number and types of features.
Back in 2017, Sun Mountain optimized the level of features and technology that they offered at a given weight.
Now, when buying a bag, a golfer knows the approximate 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 its product line.
After re-introducing the Sun Mountain 2Five Stand Bag in 2017, the company upgraded the ultra-light carry bag and re-named it the Sun Mountain 2.5+. With this upgrade, Sun Mountain improved both durability and comfort while only increasing the weight by the equivalent of two golf balls.
The 2020 version of the 2.5+ is now available, featuring all the upgrades of the intervening models with much-improved color combinations.
