The likelihood of playing the game in unpredictable conditions is only going to increase as we enter winter, but what difference could a waterproof golf bag make to you? Sun Mountain's 2027 H2NO Collection might be exactly what you require.
With sunshine often giving way to rain in a matter of minutes, waterproof equipment is essential for golfers who play in these environments. The new collection, available from approved stockists from 1 December, includes three E-Series stand bags, the H2NO E-2.5, H2NO E-3.5 and H2NO E-4.5 VLO, along with two cart bag models, the H2NO C-100 and H2NO C-130.

Each bag features waterproof fabric with a protective polyurethane (PU) coating, water-resistant, seam-sealed zips and a matching rain hood to help keep equipment dry. The collection retains the features and functionality of the original models, with the added protection of Sun Mountain’s H2NO technology.
"Golfers don’t always have the luxury of choosing when the weather cooperates," said Grant Lordan, Sun Mountain Senior Director of Marketing and Brand Strategy. "Our E-Series and C-Series bags have become popular because of their clean, understated designs that combine great looks with the quality, functionality and attention to detail golfers expect from Sun Mountain. With the new H2NO Collection, we’re building on those proven designs and adding waterproof protection so golfers can focus on their game, regardless of the conditions."

E-Series
The 2027 H2NO Collection includes three stand bag models, each offering different options for weight, storage and club organisation.
Weighing 2.0 kg, the H2NO E-2.5 stand bag is the lightest bag in the collection and is designed for golfers who prefer to walk. It features a four-way top with four full-length dividers, eight pockets and Sun Mountain’s Dual Strap System for carrying comfort. Additional features include snow fur-lined rangefinder and valuables pockets and a cooler-lined water bottle holder.
The H2NO E-3.5 stand bag offers additional storage while maintaining a lightweight design. Weighing 2.2 kg, the bag features a larger four-way top with four full-length dividers and nine pockets. The Dual Strap System provides carrying comfort for golfers who walk the course, while the additional storage makes it a practical option for those who also use a buggy.
The H2NO E-4.5 VLO stand bag combines the convenience of a stand bag with Sun Mountain’s VLO technology for a secure fit on a golf trolley or buggy. Weighing 2.6 kg, the bag features a 14-way top with 14 full-length dividers, nine pockets and the Dual Strap System. Its design provides club organisation and convenient access to equipment whether walking or using a buggy.
All three stand bags include an internal compression bottom to help keep clubs secure and organised, along with stretch internal pockets, protected valuables storage and cooler-lined water bottle holders.
C-Series
The collection also brings H2NO waterproof technology to Sun Mountain’s C-100 and C-130 cart bags, both known for their generous storage capacity and convenient access to equipment.
The H2NO C-100 cart bag features a 14-way top with 14 full-length dividers and seven pockets. Weighing 2.5 kg, the bag includes velour-lined rangefinder and valuables pockets, a cooler-lined water bottle holder and a cart strap pass-through that allows the bag to be secured without blocking pocket access.
One of Sun Mountain’s most recognised cart bag designs, the C-130 is known for its storage and organisation. The H2NO C-130 cart bag features a 14-way top with 14 full-length dividers, nine pockets and a cart strap pass-through. Weighing 2.7 kg, the H2NO C-130 also includes velour-lined rangefinder and valuables pockets and a cooler-lined drinks pocket.
The 2027 H2NO Collection will be available through authorised Sun Mountain stockists from 1 December.
