Sun Mountain 2.5+ Stand Bag: Specifications and Features


As signaled by the bag’s name, the Sun Mountain 2.5+ weighs 2.9 pounds, including straps.

The 2.5+ is the lightest carry bag that we review. We are impressed!

In other posts, we have talked about the typical tradeoff between weight, features, and quality.  With the Sun Mountain 2.5+, a golfer will see a more streamlined set of features, with fewer dividers, pockets, etc.  But Sun Mountain has done a fantastic job maintaining its high-quality standard with this bag while cutting pounds.

Getting Clubs In and Out of the Bag

2021 Sun Mountain 2.5+ TopThe Sun Mountain 2.5+ has a four-way top opening with full-length dividers and a diameter of 9″.  The four-way top was upgraded in the 2020 version with an improved top handle and a reshaped top for greater ease of use.

The number and size of the top opening of the bag are within our preferred range.  The top design easily accommodates putters with over-sized grips.  Only having four openings decreases the amount of space taken up by a greater number of padded dividers, increasing the ease of sliding clubs into the bag.

Ease of Carrying the Bag

Starting in 2018, Sun Mountain enhanced the width and thickness of the shoulder straps and the quality of the high density, contoured padding.  The Sun Mountain 2.5+ is outfitted with a lumbar hip pad for additional padding.

For ease of carrying, the 2.5 has top rim and spine handles, as well as a lift strap handle at the bottom of the bag.

Given the ultra-lightweight of the bag and its enhanced proprietary X-Strap Dual Strap shoulder strap system, the Sun Mountain 2.5+ is very comfortable to carry.


The Sun Mountain 2.5+ increased its storage and now has six pockets instead of the previous five, including:

  • A full-length clothing pocket
  • Velour-lined valuables pocket
  • Three accessory pockets, and
  • A beverage pouch

In terms of other attachment points, the bag has an umbrella attachment, towel holder, and pen holder.

The bag has a sufficient number of pockets and attachment points for carrying what a walker truly needs.

Stability of the Bag

The Sun Mountain 2.5+ Stand Bag has:

  • A matching rain hood
  • Nine color options


Sun Mountain’s has held its suggested retail price is $229.99.

The value in this bag is in its ultra-lightweight, simplicity, durability, and ease of carrying.  It also has the pedigree of being a high-quality Sun Mountain bag.
