Striding the fairways at any time is a pleasure. Having an extremely lightweight golf bag on your back increases that pleasure in that you can concentrate on your game, not the weight on your back. The Aqua Hybrid 2 stand bag from Big Max weighs 2.3kg. The bag itself is 100% waterproof with all seams sealed & all zips fully waterproof. If it does start raining then simply pop the rain hood on & your clubs will remain dry.
