Overall Score: 8.8/10 | Price: $289.99 | ASIN: B0CF9827Z1

Score Breakdown

The Verdict in 50 Words

The Sun Mountain C-130S takes the best-selling cart bag in golf history and adds retractable stand legs. It's a storage powerhouse with a 14-way full-length divider top, 13 pockets, and the Smart Strap System. Not for walkers — this is a cart rider's dream with range-day legs.

What Is the Sun Mountain C-130S?

The Sun Mountain C-130 series has been the #1 selling cart bag line for over 20 years. Named after the Lockheed C-130 Hercules cargo plane, it's built around one philosophy: maximum storage and organization for golfers who ride. The "S" variant adds retractable stand legs, making it a hybrid that works on carts, push carts, and stands upright at the driving range.

Sun Mountain introduced the C-130S to answer a surprisingly common customer request: "Does it have legs?" While the need for stand legs on a dedicated cart bag puzzled some purists, the demand was clearly there. The result is a bag that gives riders the full C-130 experience with the convenience of not having their bag tip over at the range.

The 2024/2025 versions continue to refine the formula with improved cooler pocket placement, updated colorways, and the same obsessive attention to cart-friendly design that made the original a legend.

What People Love

14-Way Full-Length Dividers (Praised by ~85% of reviewers)

This is the feature that comes up again and again. Every single club gets its own dedicated, full-length slot — including an oversized putter well that accommodates SuperStroke and other jumbo grips.

"Very pleased with 14 separate locations for clubs. Makes it super easy to get long clubs in and out. Love the slot for my oversized putter." — Amazon reviewer

"Prior to this, I had the Ping Hoofer golf bag. While I thought it was a decent bag, it pales in comparison to this one. With the Hoofer bag my irons would consistently get tangled with each other even though they had their own dedicated slot." — Amazon reviewer (22 helpful votes)

The reverse-oriented top positions your putter and wedges at the front when on a cart, so your scoring clubs are always within easy reach.

Storage That's Actually Accessible (~80% mention this)

With 13 pockets, the C-130S has more storage than most golfers know what to do with. But what separates it from other pocket-heavy bags is that every pocket remains accessible when the bag is strapped to a cart — thanks to Sun Mountain's cart strap pass-through design.

"The cart strap pass-through design means you can strap this bag tight to a cart and still access all pockets. Most bags you lose access to one side when strapped. Not this one." — Reddit r/golf

The lineup includes:

"I can fit a 6 pack of cans with a little bit of ice and it's lined to keep it cold!" — Reddit user on the 2025 cooler pocket redesign

The Smart Strap System (~60% mention this)

Sun Mountain's proprietary system uses Velcro straps on the back of the bag that attach to any golf cart basket, preventing the bag from shifting or rotating.

"The cart strap lock system is wonderful, my bag never shifts or slides on the cart." — Reddit r/golf (45 upvotes)

"One of the worst sounds in golf is when the bag falls off a cart and crashes onto the cart path. If you use the Smart Strap System that will never happen." — Independent Golf Reviews

Four-Handle Design (~40% mention this)

Built-in handles on both sides of the top, one on the back, and one on the bottom make the bag easy to grab from any angle.

"The four handle design is underrated. Makes it so easy to grab from any angle when loading in/out of the car or onto a cart. Small detail that makes a big difference." — Reddit r/golf

Color Selection

The standard C-130 comes in 13+ stock colorways plus custom "build your own" options. The C-130S offers a smaller but still respectable 5 colorways. This matters more than most companies realize — color is consistently one of the top factors in bag selection.

Durability and Build Quality

Multiple reviewers report using their C-130/C-130S bags for 5-7+ years with minimal issues. The construction quality is frequently praised.

"I've had it for 5-6 years and the rest of the bag is still in perfect condition." — MyGolfSpy commenter

"During my years in golf retail, I sold hundreds of golf bags. When someone came in looking for a recommendation, my default was to give them a Sun Mountain C-130. I've never seen a golfer unhappy with one nor have I ever seen one returned for a defect." — Plugged In Golf / former retail worker

What People Don't Love

Weight: 6.8 lbs Empty (~15% of reviewers mention this)

At 6.8 pounds empty, the C-130S is firmly in cart bag territory. Despite the stand legs and shoulder strap, this is not a carry bag.

"At 6.8 lbs empty, this is NOT a carry bag. Don't even try. It's great on a cart or push cart, and the stand is fine for the range, but if you want to walk and carry, get a proper stand bag." — Reddit r/golf

The Rain Hood Is Awful (~10% complaint rate)

This is the most passionate negative feedback. The rain hood is difficult to put on and nearly impossible to manage in a hurry.

"The hood is AWFUL! Awkward fit, tricky to attach. Very difficult to remove and replace clubs, especially from certain slots. Caught in a sudden downpour, couldn't replace hood quickly, threw a towel over clubs instead." — Amazon reviewer (18 helpful votes)

"Sun Mountain needs to fix this." — Multiple reviewers

Tipping When Standing Unassisted (~8% mention this)

Without the stand legs deployed (on the regular C-130), the bag tends to tip forward, especially with golf balls loaded in the front pocket. The C-130S mostly solves this with its stand mechanism, but the regular C-130 has this issue.

"The bag always seems to want to tip towards the front when on a flat floor. It seems they haven't really balanced the bag for once you actually have balls in the front pocket." — Reddit r/golf

Cart Rotation (~5% mention this)

Some users report the bag rotating 45 degrees on the cart over several holes, requiring readjustment.

"By hole 3-4 it's basically turned 45 degrees. So I'm always having to readjust the bag on the cart every 3-4 holes." — Reddit r/golf

Size Can Be Overwhelming (~5% mention this)

The C-130S is a big bag. Some golfers find it excessive.

"It's a great bag but it's MASSIVE. If you're someone who likes a more compact setup, look elsewhere. The storage is unreal but it takes up the entire cart basket." — Reddit r/golf

Occasional Zipper Issues (~3% over time)

A small number of long-term users report zipper problems after extended use.

"I bought a Sun Mountain C130 cart bag at the beginning of last year. It's a great bag but all of the sudden I'm having issues with 2 zippers." — GolfWRX

Stand Spring Issue on Early Models

Early production runs of the hybrid/stand models had stand spring issues. This has been corrected, but buying directly from Sun Mountain or authorized retailers is recommended.

"Early versions had issues with the stand spring not being correct. They would disconnect. It's been fixed but you never know if an old version is still in a store's warehouse." — Reddit r/golf

No Dedicated Water Bottle Holder

Unlike some competitors, the C-130S lacks a dedicated external water bottle pocket, though the cooler pocket can serve this purpose.

Competitor Comparison

The C-130S's main differentiator is the stand mechanism combined with cart-bag-level storage. If you don't need the stand, the regular C-130 is lighter, cheaper, and comes in more colors. The PING Pioneer is a strong alternative if you want something slightly lighter and less expensive.

Who Should Buy This Bag

✅ Golfers who ride 80%+ of the time but want a stand for range sessions

✅ Storage maximalists who bring rain gear, snacks, beverages, and accessories

✅ Organization obsessives who want every club in its own slot

✅ Cart golfers tired of bags shifting and rotating on the cart

✅ Golfers looking for long-term durability — these bags last 5-7+ years

Who Should Skip This Bag

❌ Walkers and carriers — at 6.8 lbs empty, this is not a carry bag

❌ Minimalists who want a compact, streamlined bag

❌ Rainy climate golfers who need excellent weather protection (rain hood is poor)

❌ Budget shoppers — at $290, there are cheaper options

❌ Push cart users who need a perfect fit — the stand legs can interfere with some push cart models

The Bottom Line

The Sun Mountain C-130S is the cart bag that other cart bags aspire to be — with the bonus of retractable stand legs. It's been the best-selling cart bag for 20+ years because it nails the fundamentals: unmatched organization, smart cart-specific features, accessible storage, and build quality that lasts.

Its weaknesses are real — the weight, the terrible rain hood, and the premium price — but for the riding golfer who occasionally needs a stand, there's simply nothing better on the market. The 85% positive sentiment across 580+ reviews confirms what golf retailers have known for two decades: you can't go wrong with a C-130.

Buy the Sun Mountain C-130S if you ride and want the absolute best cart bag experience with range-day versatility. Skip it if you walk, carry, or need a compact bag.
