I'm a fan of a light golf bag. Make it as light as you can without making it as disposable as H&M clothes. I walk a golf club with a lot of hills, and so taking a few lbs. off my back during the uphill hikes is nice.
Sun Mountain makes several light golf bags, including the 2Five, which is the lightest full-featured bag on the market. (You can find a Sunday bag lighter, of course, since it's smaller.) The 2Five has carbon-fiber legs, strong plastics and as lightweight a fabric that can reliably function on a golf bag. However, the company has chosen to upgrade the bag to better materials for improved durability at the cost of...3 ounces, or the weight of a couple of golf balls, which I usually have too many of in my bag in the first place.
So, the new model, the 2.5+ will have more storage and comfort features in a more durable package while keeping the same $220 price point.
The bag's fabric has been improved from 70 denier to 100 denier, while shoulder straps are wider and have more padding. Also, the company added a zippered spine pocket for added storage and a beverage pouch, which is super handy on the 3Five model I've used on and off for years. It has a 9-inch top with four full-length club dividers, and it has five pockets, including a velour-lined valuables pocket and a full-length clothing pocket.
Of course, mainstays of Sun Mountain bags remain, too, including the handle built into the top, the X-strap shoulder straps, the lumbar hip pad and other features. The 2.5+ is available in eight color combos, and the rain hood matches.
If you're looking to keep carrying but have a lesser payload as you march 18, you may want to look at the 2.5+.
