Sun Mountain H2NO Lite Cart Bag Review

There’s an awful lot to love about the Sun Mountain H2NO Lite cart bag, especially if you're a lady golfer or anyone looking for a lightweight but spacious option to fit on their trolley. For starters there’s the fact that this golf trolley bag is completely waterproof. You’ll notice how thick the nylon fabric feels - you could say it’s a cross between one of the best waterproof golf jackets and a tent - a special coating on the surface means that rain water literally runs off the surface. The zips and seams are cleverly taped to ensure that all your belongings remain dry in even the harshest of weather conditions, making it one of the best waterproof golf bags we've tested in recent times.

One of the big problems ladies face is having the strength to lift the golf bag out of the boot of the car and onto our trolley. The H2NO Lite completely resolves this. At just 2.6kg when empty it’s only a little heavier than lifting two bags of sugar - that’s incredibly lightweight. Even after you’ve added your clubs, balls, waterproofs, drink and accessories, it’s more than light enough for even the most fragile lady to lift. 

We love the fun and fashionable berry color, although there are actually nine vibrant colors to choose from, so you can pick from your favourite colour. The attention to detail in the design of this golf bag is spot-on. The full length club dividers inside the bag make it really easy to keep every club separate, protecting the shafts from scratching and the heads from clanging together and marking, plus the separate putter holder at the end is in perfect placement.

There are pockets galore including a pocket that acts like a cool bag to keep your drink chilled on a warm day, a velour lined pocket to place your watch, car keys, phone or other valuables, big side pockets for your waterproofs and we particularly love the little velcro patch on the outside of the bag where you can stick your glove if take it off to putt and don’t want to lose it.

At a fraction over £300/$325 the Sun Mountain H2NO Lite isn’t overly cheap but we reckon it’s a bag that will last for years if you look after it and you’ll certainly thank us for recommending it next time it’s raining - you won’t even need to get your umbrella out!

As a consistent three-handicapper who plays competitive club golf at Parkstone and the Isle of Purbeck courses in Dorset every week, Carly is well-versed in what lady golfers love. Her passion for golf and skill at writing combine to give her an unbeatable insight into the ladies game.  

Carly’s role at Golf Monthly is to help deliver thorough and accurate ladies equipment reviews, buying advice and comparisons to help you find exactly what you are looking for. So whether it’s the latest driver, set of irons, golf ball, pair of shoes or even an outfit, Carly will help you decide what to buy.
Over the years Carly has been fortunate to play some of the greatest courses in the world. Her view ‘from the ladies tee’ is invaluable. She ranks Sea Island, Georgia, USA, where she met her husband, world-renowned golf coach Dan Frost, among her favourite golf resorts. Their aptly-named eight-year-old son Hogan is already hitting the ball as far as Mum and will undoubtedly be a name to watch out for in the future.
Carly is a keen competitor and her list of golfing achievements are vast. She is a former winner of the South West of England Ladies Intermediate Championship, a three-time winner of the European Media Masters and she once beat an entire start-sheet of men to the title of Times Corporate World Golf Champion. She has played for both the Dorset and Surrey County Ladies first teams and is known for her excellent track record at matchplay.

Carly holds the ladies course record (68) at her home club Parkstone and her lowest competition round (seven-under-par 65) was carded in the pro-am of the Irish Ladies Open at Killeen Castle, playing alongside Solheim Cup superstar Anna Nordqvist. Although her current handicap index has crept up to 3.7 since Covid she has her sights firmly set on achieving that elusive scratch handicap and hopefully playing for her country when she’s 50.
