What They Have in Common
Both weigh in at 4.8 lbs empty and list in the $270–$290 range. Neither brand publishes a waterproof claim for these models, and neither publishes a rain hood or insulated pocket. Both are carry-oriented bags aimed at golfers who want something lighter than a cart bag without going ultra-minimalist.
Where They Differ
Stand Legs and Straps
The Players S4 has stand legs and a double strap. The Swift Sunday has a single strap, and Sun Mountain doesn't publish whether it has stand legs at all. That ambiguity matters. A bag you can set down without leaning it against something is a fundamentally different object than one you can't, especially over 18 holes. The double strap on the Titleist distributes 4.8 lbs across both shoulders; a single strap means that weight rides one side all day. Half a pound doesn't sound like much until it's the back nine in August, and neither does a second strap.
Organization
The Swift Sunday has a 5.25-inch, 3-way top with 6 pockets, two of them velour-lined for valuables, plus a zip-off ball pocket that's a genuinely handy feature for range days or quick loops. The Players S4 has a 4-way top with full-length dividers — meaning shafts run the length of the bag and don't tangle at the bottom — and 8 pockets total, including a magnetic tee pocket and an external water bottle slot. More dividers stop grips from knotting together and make a missing club obvious before you drive off the green. Neither publishes a putter well.
Cart Compatibility
The Players S4 has a cart strap tunnel, which means when it rides, it straps in properly without you having to thread the strap around everything. A cart strap pass-through is the difference between strapping in once and re-threading it every time you want a ball. The Swift Sunday doesn't publish a pass-through, so that's unknown. The S4's stand legs also mean it can do both jobs — walk and ride — without compromise.
Price
The Swift Sunday lists at $289.99. The Players S4 lists at $270. The Titleist is the less expensive bag with more features on paper.
Who Should Buy Which
Get the Titleist Players S4 if:
- You want one bag that walks and rides without asking you to sacrifice anything
- You care about shaft organization — full-length dividers matter if you've ever pulled out a tangled mess at the first tee
- You ride some rounds and want the cart strap tunnel to do its job
- The $20 savings over the Sun Mountain means anything to you
Get the Sun Mountain Matchplay Swift Sunday if:
- You specifically want a dedicated carry setup and the minimalist 3-way top appeals to you
- The zip-off ball pocket is actually useful to your routine — range sessions, par-3 courses, quick 9s
- You prefer fewer divider slots and don't mind the single strap
- Stand legs genuinely don't factor into how you use the bag
The Bottom Line
These two bags weigh the same and list within $20 of each other, but they're not the same kind of object. The Titleist Players S4 stands on its own, carries on two shoulders, organizes clubs the length of the bag, and works on a cart without fuss. The Swift Sunday asks you to accept some published unknowns — stand legs, rain hood, material — and a single strap, and lists higher for it. I'd guess the Swift Sunday has a specific buyer in mind, someone doing walkable par-3 rounds or range work, but for most rounds in most conditions the Titleist does more and lists lower.
