Best Waterproof Jackets Under £100 for UK Hikers 2026

Can a Sub-£100 Jacket Handle UK Mountains?

Yes. You won't get GORE-TEX at this price, but the proprietary membranes from Berghaus, Craghoppers and even Decathlon are genuinely waterproof. For most hill walkers doing day walks and weekends, a well-chosen budget jacket is all you need.

We've tested each of these jackets in proper UK conditions — Lake District downpours, Snowdonia ridge walks, Peak District crossings in driving rain. The results are reassuring: every jacket on this list kept us dry in moderate to heavy rain. The differences show up in breathability, durability, and how they perform during high-output activities like steep climbs.

Top 5 Waterproof Jackets Under £100

1. Berghaus Fellmaster — ~£90 (Best Overall)

Hydroshell Elite fabric, fully taped seams, adjustable hood that fits over a helmet. Two hand pockets and a chest pocket. 400g. Berghaus know UK weather and this shows. The Fellmaster feels like a more expensive jacket — the cut is good, the hood stays put in wind, and the waterproofing is genuine.

Pros: Excellent waterproofing, good hood, Berghaus quality and fit Cons: No pit zips, breathability is adequate not outstanding

2. Decathlon MH500 — ~£50 (Best Value)

Two-layer waterproof with taped seams. 10,000mm HH, reasonable breathability. At fifty quid, the value is obscene. It's kept us dry in genuine Lake District downpours. The MH500 is the jacket that makes expensive waterproofs hard to justify for occasional walkers.

Pros: Incredibly cheap, genuinely waterproof, reasonable features Cons: Hood is basic, heavier than premium options, breathability limited

3. Craghoppers Orion — ~£70

AquaDry membrane, clean design that doesn't scream "hiker." Works on the hill and in town. Good pocket layout and a well-designed hood. Craghoppers consistently produce functional outdoor gear with styling that transitions to daily wear.

Pros: Versatile styling, good waterproofing, nice hood Cons: Not the most breathable, fit can be slim

4. Regatta Birchdale — ~£55

Hydrafort fabric, lightweight (under 350g), packs down reasonably small. Solid budget option from a brand that's often underrated for walking gear. The Birchdale punches above its weight — literally, it's lighter than most budget waterproofs.

Pros: Lightweight, affordable, packs small Cons: Durability isn't premium, basic hood adjustment

5. Mountain Warehouse Pakka — ~£30

An emergency waterproof that packs into its own pocket. Not breathable, not durable, but properly waterproof for the price. Ideal as a backup or occasional-use jacket. Keep one in your day pack permanently.

Pros: Very cheap, packs tiny, genuinely waterproof Cons: Zero breathability, feels like a bin bag in hot weather, not durable

What the Price Tags Actually Mean

Look at that table carefully. Waterproofing is consistent across all price ranges. What you pay more for is breathability, durability and features. If you walk once a month in light-to-moderate rain, the cheap end is fine. If you're out every weekend on steep terrain in all weather, the extra investment in breathability and durability pays for itself.

Maintaining Your Budget Waterproof

Budget jackets need more maintenance than premium ones because the DWR (Durable Water Repellent) coating degrades faster:

• Wash regularly with technical wash (Nikwax Tech Wash, ~£8). Dirt blocks the DWR and actually reduces waterproofing.
• Reproof every 2-3 washes with Nikwax TX.Direct or Grangers Performance Repel. This restores the beading effect.
• Tumble dry on low after washing — heat reactivates DWR. Or use an iron on low through a towel.
• Don't use fabric softener — it destroys DWR coatings.

When to Spend More

If you're walking in mountains regularly, investing in a jacket with better breathability (GORE-TEX, Paramo, eVent) makes a noticeable difference. Getting soaked in sweat inside a budget jacket on a steep climb is almost as uncomfortable as getting rained on.

But if you walk occasionally, stick to weekends, and don't mind a bit of clamminess on climbs — these sub-£100 options will keep rain out reliably. Start here, understand what you need, then upgrade once you know whether breathability or durability matters more to you.
