Best 10,000mm Waterproof Jackets for Hiking (2026)

Choosing the best 10,000mm waterproof jacket comes down to a simple question: how much rain do you actually hike in? A 10,000mm (10k) waterproof rating handles moderate rainfall, wind-driven drizzle and the occasional downpour. That's exactly what most day hikers and weekend backpackers face on a regular basis. You get solid protection without the bulk, stiffness or price tag of a 20k+ hardshell.

I've tested two of the most popular 10k jackets on the market across a range of conditions: the Marmot PreCip Eco and the Columbia Watertight II. Here's how they compare and which one deserves a spot in your pack.

What Does 10,000mm Waterproof Actually Mean?

Before diving into specific jackets, it helps to understand what that "10,000mm" number represents. Manufacturers test waterproofing by placing a tube of water over the fabric and measuring the height (in millimetres) the water column reaches before moisture seeps through. The higher the number, the more water pressure the fabric can withstand.

Here's a rough guide to what different ratings handle in practice:

• 5,000mm: light rain and brief showers. Fine for a quick walk, but it'll wet out in sustained rainfall.
• 10,000mm: moderate rain and full-day hikes. Handles most conditions you'll meet on established trails.
• 20,000mm+: heavy, sustained rain, high winds and extended mountain exposure. Built for serious foul weather.

For most hikers who stick to day hikes and moderate multi-day routes, a 10k jacket hits the practical sweet spot. You're paying for genuine rain protection without spending extra on features you'll rarely need. If you regularly hike in heavy mountain rain or multi-day storms, read the 20,000mm waterproof jackets guide instead.

The Best 10,000mm Waterproof Jackets Compared

Marmot PreCip Eco: Best Overall Quality

The Marmot PreCip Eco consistently appears on "best hiking jacket" lists, and for good reason. What sets it apart from other 10k jackets isn't the waterproof rating itself, since both jackets here share that same 10,000mm threshold. It's the quality of the construction. The seam sealing is meticulous, the zips feel solid, and the overall finishing is a clear step above what you'd expect at this price.

Marmot uses their proprietary NanoPro membrane, which provides the 10k waterproof rating while offering decent breathability for a non-Gore-Tex jacket. In moderate rain, the kind you'll meet on most UK and European trail days, the PreCip keeps you reliably dry. The pit zips are a genuine bonus here: on warmer days or during steep ascents, you can dump excess heat without removing the jacket entirely.

The hood deserves a mention too. It's fully adjustable and shaped to fit over a climbing helmet if needed, though most hikers will simply appreciate that it stays put in the wind and doesn't obstruct your peripheral vision.

It's a versatile jacket too. The styling is clean enough to wear around town, the fit works with or without a mid-layer underneath, and Marmot offers it in a wide range of colours and sizes. That makes it just as happy on travel days and everyday wet weather as it is on the trail.

At around 310g (10.9 oz), the PreCip is the heavier of the two jackets here. It's heavier than the Columbia but lighter than many competing jackets at this price point. It packs down into its own pocket reasonably well, though it's not quite as compact as the Watertight II.

Best for: Hikers who want the best build quality and finishing in the 10k category. If you're willing to spend a little more for a jacket that feels genuinely well-made, the PreCip is the one to get.

Columbia Watertight II: Best Value

The Columbia Watertight II occupies a clever middle ground in the jacket market. It's more durable and lighter than true budget options, yet significantly cheaper than the Marmot. At roughly $60, it offers a price-to-performance ratio that's difficult to beat.

Columbia's Omni-Tech membrane provides the 10k waterproof rating with fully sealed seams, and in practice it performs exactly as you'd hope. Moderate rain, persistent drizzle, wind-driven showers: the Watertight II handles them all without fuss. For long-distance hikers who need reliable rain protection day after day without worrying about babying their gear, this jacket makes a strong case for itself.

At 280g (9.8 oz), it's the lighter of the two jackets here and packs down impressively small. That matters when you're counting grams for a thru-hike or trying to fit everything into a 40-litre pack.

The trade-off for the lower price is refinement. There are no pit zips, so ventilation relies entirely on the main zip and whatever airflow the cut allows. The hood adjustment is functional but basic, a single drawcord rather than the multi-point adjustment you get on the Marmot. The fabric itself feels somewhat less premium, though it's perfectly serviceable and has held up well in testing.

Best for: Long-distance hikers and budget-conscious backpackers. If you want a no-nonsense rain jacket that does the job without costing much, the Watertight II delivers.

What to Look for in a 10k Waterproof Jacket

Beyond the waterproof rating itself, a few features separate a good hiking jacket from a frustrating one:

Sealed Seams

Every stitch hole in a jacket is a potential leak point. Fully taped seams cover those holes with waterproof tape on the inside of the jacket, ensuring water can't seep through. Both jackets reviewed here have fully sealed seams, but cheaper alternatives sometimes cut corners with "critically taped" seams, where only the most exposed seams are sealed. For hiking, always choose fully taped.

Pit Zips

Underarm ventilation zips let you regulate temperature without removing the jacket. The Marmot PreCip Eco includes them; the Columbia Watertight II does not. If you run warm or hike in variable conditions, pit zips are worth having.

Hood Design

A good hiking hood should be adjustable (front-to-back and side-to-side), stay put in wind, and allow peripheral vision. A stiffened brim that keeps rain off your face is a bonus. The Marmot has the better hood of the two; the Columbia's is more basic.

Packability

A rain jacket spends most of its time stuffed in the bottom of your pack. Both jackets here pack into their own pockets, but the Columbia is the more compact. Consider how much space you can spare. For ultralight setups, every cubic centimetre matters.

When to Upgrade to 20,000mm

A 10k jacket handles most hiking situations, but there are scenarios where you genuinely need more protection:

• Multi-day mountain routes where you can't escape sustained heavy rain
• Winter hiking with snow, sleet, and high winds
• Exposed ridgelines where wind-driven rain creates extreme water pressure on the fabric
• Heavy pack pressure: a loaded backpack's shoulder straps and hip belt press against the jacket, reducing its waterproof performance in those contact areas

If any of these describe your regular hiking, consider stepping up to a 20k+ rated jacket. The 20,000mm waterproof jackets guide covers the best options in that category. It's also worth pairing your shell with waterproof hiking trousers for full coverage on exposed days.

For day hikes, three-season trail walking, and occasional weekend backpacking trips, a well-made 10k jacket is genuinely all you need. Don't let marketing pressure push you into spending more than the conditions demand.

The Verdict

Both jackets deliver reliable 10,000mm waterproof protection, but they each serve a slightly different hiker:

• Marmot PreCip Eco: best overall quality and the most versatile pick. Superior seam sealing, pit zips and refined construction, and it works equally well on the trail and around town. Worth the extra cost if build quality matters to you.
• Columbia Watertight II: best value. Lighter, cheaper and durable enough for long-distance trails. The smart choice for thru-hikers and budget-conscious backpackers.

If I had to pick just one, I'd go with the Marmot PreCip Eco. The finishing and seam quality are noticeably better than the competition, and the pit zips make a real difference on warmer days. But honestly, you won't be disappointed with either of these. They both do exactly what a 10k jacket should do, and they do it well.
