20,000mm Waterproof
Properly Waterproof at 95 Grams
The J.Lindeberg Shay Rain Jacket pairs a 20,000mm waterproof rating and taped seams with a fabric that weighs 95 g/m². Laminated windproof construction, four-way mechanical stretch, and a two-way waterproof front zip — protection that doesn't feel like armour.
Key Features
20,000mm Waterproof, Taped Seams
A genuine waterproof rating, and taped seams so the water doesn't get in through the stitching instead. Both matter; most jackets only claim one.
20,000 g/m²/24h Breathability
Matched to the waterproof rating, which is the point — it keeps rain out without trapping your own sweat in.
Just 95 g/m²
Light enough to carry all round on the chance of rain rather than leaving it in the car.
Four-Way Mechanical Stretch
Give built into the construction rather than added with elastane, so the swing isn't fighting a shell.
Laminated Windproof Build
Blocks wind as well as rain, which on an exposed course is often the bigger problem.
Two-Way Waterproof Zip
A sealed front zip that opens from the bottom for room through the hips when you sit or swing.
Velcro Cuffs & Zip Pockets
Set the cuffs over a glove, and zipped pockets so nothing works loose in the wet.
75cm Centre Back
Measured on a size M and graded. Long enough to cover properly without catching at the hip.

Why You'll Love It
Rain jackets usually fail in one of two ways: they leak, or they keep the rain out and your sweat in. The numbers here answer both — 20,000mm waterproof and 20,000 g/m²/24h breathability, which is a matched pair rather than one impressive figure covering for a weak one. Taped seams mean the water can't sneak through the stitching. And at 95 g/m² it packs down small enough that it actually comes with you, which is the only rain jacket that was ever any use.
