How to Choose a Waterproof Jacket for Hillwalking

Of all the kit you carry up a Munro, the waterproof jacket — the "hardshell" — is the one your comfort and safety depend on most. Scotland's mountains serve up wind-driven rain, sleet and spindrift in every season, and a jacket that fails you high on a ridge is not an inconvenience, it's a genuine danger. Rather than name specific models that date quickly, this guide explains what actually matters so you can choose well and judge any jacket for yourself.

Get a proper hardshell, not a "showerproof" jacket

The first and most important distinction: for the Scottish hills you need a genuine waterproof hardshell with taped seams, not a water-resistant softshell or a "showerproof" jacket. Only a fully taped, waterproof-membrane jacket will keep out sustained mountain rain. This is the non-negotiable baseline — everything below assumes you're choosing between real hardshells.

Waterproofing and breathability

Waterproofing is measured as a hydrostatic head (in mm); for serious mountain use you want a robust rating that will cope with driving rain and pressure from pack straps. But waterproofing alone isn't enough — you also sweat hard climbing, so breathability matters almost as much, otherwise you get wet from the inside. The best jackets balance the two. Membranes like Gore-Tex are the known quantity, but several own-brand and alternative membranes now perform very well for less money. Whatever the membrane, its performance depends on the outer face fabric's DWR (durable water repellent) coating staying effective — which needs occasional re-proofing (see below).

The details that make or break a jacket

• The hood. The single most important feature for Scotland. It must be helmet-compatible (or at least generous), have a stiffened peak, and adjust to move with your head and seal against wind-driven rain. A poor hood ruins an otherwise good jacket.
• Pockets above the hipbelt. Hand and chest pockets need to sit above where a rucksack hipbelt and chest strap cross, or they're useless when you're actually wearing a pack.
• Pit zips. Underarm vents let you dump heat on a hard climb without taking the jacket off — genuinely useful in Scotland's mild, wet conditions.
• Adjustable cuffs and hem to seal out wind and rain, and a good full-length front zip with a storm flap.
• Weight vs durability. Ultralight jackets pack small but wear through faster under a pack and on rock; a slightly heavier, more robust jacket lasts longer and stands up to Scottish use.

Fit and care

Try it on over your usual layers — it needs room for a fleece or insulated mid-layer beneath, without being so baggy that it flaps. Check you can raise your arms and turn your head with the hood up without the hem riding up. Once you own it, re-proof the DWR periodically (wash-in or spray-on) and wash it with technical cleaner rather than normal detergent — a neglected jacket "wets out" and stops breathing. Your jacket is one layer in a system; see our layering system guide for how it all works together, and the packing list for the rest of the kit.
