The ifrothgolf review
A premium full-zip waterproof from the Swedes who basically wrote the book on golf rainwear. The Armstrong uses GORE-TEX Paclite Stretch, a two-layer shell built to be light and packable rather than bombproof and bulky. It is aimed at the golfer who wants serious wet-weather protection that still swings like normal apparel and folds down small enough to forget about until the heavens open.
What's great
The waterproofing is the real deal, not a marketing claim. It will keep you bone dry through a full round of steady rain, and the GORE-TEX breathability means you are not swimming in your own sweat by the back nine. The stretch is the headline though: most truly waterproof jackets feel like cardboard over your swing, and this one genuinely moves with you. It packs down to almost nothing, the cut is athletic rather than tent-like, and Galvin Green build quality means it will outlast several cheaper jackets. PFC-free and bluesign approved if that matters to you.
Worth knowing
It is expensive, and the Paclite Stretch is a thinner shell than the brand's flagship insulated models, so it offers little warmth on its own and needs a layer underneath in winter. The fit runs athletic and trim, so size up if you carry a bit or like room for a mid-layer. The lightweight fabric, while brilliant for packing, is less rugged than heavier shells and wants careful washing with a tech wash to keep the DWR working. Real-world stock and pricing swing a lot, it often sells at a discount, so paying full RRP can sting when patience saves you a chunk.
The verdict
If you play through British winters and want one waterproof that actually keeps its promises while still letting you make a proper swing, this is about as good as it gets short of the heavier insulated jackets. Not cheap, and not the warmest, but for honest all-weather protection and packability it earns its keep. Buy it on offer if you can.
