A backpacking rain suit has one job: keep you bone-dry while your body cranks out heat on the trail. The real test isn’t a drizzle — it’s hours of steady rain with a loaded pack, where the wrong suit turns into a sweaty plastic bag. The best options here balance a real waterproof membrane against breathability you can feel, and they all crush down small enough to forget they’re in your pack.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You need a shell that sheds rain, vents steam, and packs light, and this breakdown of the best backpacking rain suit options shows which ones actually deliver on all three.
Our Picks at a Glance
How To Choose The Best Backpacking Rain Suit
Finding a good rain suit means looking past the word “waterproof” and digging into the numbers behind it. Two specs matter most: how much water pressure the fabric stops, and how much sweat vapor it lets escape.
Waterproof vs. breathable — the real trade-off
A higher waterproof rating means the fabric can hold back heavier, harder rain without leaking through. Check for a number in millimeters — something like 5,000mm handles steady rain, while a 20,000mm rating shrugs off a serious downpour.
Fit and movement matter more than you think
A rain suit that binds across the shoulders or rides up when you reach will ruin a hike long before the rain does. Look for a cut that leaves room for a base layer and a mid layer, plus details like adjustable hoods, cuffs, and ankle openings that seal the weather out without restricting your stride.
Packable weight is the backpacker’s currency
Every ounce counts when it lives in your pack for days without rain. The best trail suits are light enough to forget and compress into a small storage bag so they tuck into a side pocket. Heavier suits with extra features belong in the car, not on your back.

In-Depth Reviews
1. 33,000ft Men’s Rain Suit
Our pick — 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The trail favourite that keeps you dry and sweat-free through a full day out.
This is the suit that owners reach for when the whole day hinges on staying comfortable. The 5,000mm H2O waterproof rating stops steady rain, and the matching 5,000g/m2/24hour breathability rating lets body heat escape so you don’t end up soaked from the inside. That moisture-wicking liner is the feature buyers praise most — it’s the reason fishermen report no sweating even after hours in West Virginia rain.
The fit earns real affection too. Real zippered pockets, a foldable hood, and a full collar zip make it feel like a proper piece of kit, and a 6’2″, 200lb owner found a large fits true-to-size. It’s light enough to forget it’s in your bag, and the whole set packs down small for the trail. The versatility stretches to golf — two suits passed a heavy rain test on a Scotland trip with no swing restriction.
Sizing is the one thing to read carefully, since some owners find it runs small while others call it true-to-size. Buyers report it’s roomy and well-made overall, so if you’re between sizes, leaning up is the safer bet. For the price, the combination of protection, packability, and comfort is hard to argue with.
trail-tough shell
- Breathable liner stops the sweat-soak effect on long days
- Real zippered pockets and foldable hood add everyday usability
- Lightweight and packable for easy stashing
sizing runs big
- Sizing feedback is split — some say true-to-size, others say size up
- Hood is stored with velcro, which some find fiddly
top pick: The one to grab for hiking, fishing, and golf where comfort matters as much as dryness.
verify fit: The only real risk is the fit — check the size chart before you order.
2. BASSDASH Men’s Rain Suit
A camo-ready shell that blocks both wind and water without cooking you.
The BASSDASH is built around a 100% PU shell over a polyester inner, with fully taped seams that keep every stitch line from becoming a leak point. Its 5,000mm H2O waterproofing handles a full day of rain — owners mention staying dry from morning to night — and the 3,000gr/m2/24hrs breathability keeps it from turning into a sauna, which is why hunters in warmer climates call it lightweight and not too hot.
What stands out is the versatility across outdoor jobs. A washbay attendant uses it to shrug off grease, oil, and mud, then hoses the whole suit down and hangs it to dry. Hunters praise the build for an Argentinian trip, anglers call it comfortable to fish in, and the whole thing packs into a small travel bag. The fit is mostly true-to-size with a slightly relaxed cut, though tall buyers over 6’5″ should size up for extra sleeve length.
The honest trade-offs are weight and small details. One owner called it heavy and unsuitable for backpacking where every ounce counts, so it suits camping and fishing better than ultralight trails. A couple of owners hit a broken velcro stitch or a short jacket on a tall frame. None of these are dealbreakers for its main audience — it’s a durable, breathable workhorse for wet outdoor days.
rugged camp gear: The fully taped seams and PU shell make this a genuine all-weather shell for hunting, fishing, and grimy work.
heavy for hikes: Weight is the catch — bring it when ounces don’t rule your pack.
3. KEMIMOTO Motorcycle Rain Suit
The toughest waterproof rating here, built for riders who eat highway rain.
The KEMIMOTO is the heavy hitter of this list, with a 20,000mm waterproof rating — four times the water pressure of the standard 5,000mm suits. That number isn’t just bragging: one rider wore it through daily rain storms on a five-day, 2,000-mile trip from Virginia to Florida and stayed 100% dry. The “Dual Breathable System” (two back-to-back airflow channels) keeps the inside from turning tropical, with a 3,000g/m²/24h breathability rating.
Riders specifically praise the true sizing and solid construction, and the suit doubles as a comfortable windbreaker at 31°F. There are sewn-in boot covers that keep the water off your ankles, and the whole thing is lightweight and portable for strapping to a bike. Abrasion resistance is part of the design, so it holds up to the road.
There is one recurring gripe: you have to slip your boots off to get the pants on, since the pant legs don’t open fully. On the road, that’s a real annoyance when you get caught mid-ride. Owners note the zipper runs reversed and the boot covers are visible, but for straight-up rain protection at highway speed, nothing here touches the 20,000mm rating.
bike best: The pick for motorcyclists who need maximum waterproofing and can live with boot changes.
needs practice: The non-opening pant legs mean boots come off first — plan for it.
4. Rain Suit for Men (Burjosy)
A windproof two-piece that proves you don’t need to overspend on dry gear.
The Burjosy suit wins people over on fit and fabric quality — the two things owners mention most. It’s a waterproof, windproof set with a breathable lining, a concealable hood, and reflective strips that keep you visible in low light. Customers note it keeps a worker dry in torrential rain out at sea in the Bahamas, and the cut allows free movement even over a jacket. That ease of motion, plus the lightweight build, makes it a solid pick for fishing, golf, and outdoor work.
What makes this such a strong value is how much protection comes for the money. The jacket and pants store into a small storage bag, and the detachable hood adds versatility across seasons. One owner used it comfortably from late summer through winter cold without losing that comfort. The water resistance gets solid marks, though the fabric is untested against truly heavy downpours by some.
The sizing chart is the one thing to respect. A 5’3″, 220lb buyer found an XXL too big and an XL just right over a jacket, while a few note the pants have an internal leg issue. International shipping was the biggest complaint, not the suit itself. For a windproof, reflective, packable set at this tier, it’s a lot of gear for the money.
budget-friendly coat: Great fit and fabric quality for the price, with windproofing and reflectivity as bonuses.
size up needed: The fit runs generous — measure against the chart first.
5. RainRider Rain Suit
A three-piece rain system with removable shoe covers and serious build quality.
The RainRider stands out with its 10k waterproof and 8k breathability membrane — a balanced spec that’s genuinely breathable for hours without feeling clammy. It’s a three-piece set that adds removable shoe covers to the usual jacket-and-pants combo, plus a three-way adjustable hood and sealed seams for extra leak protection. The build quality is the thing owners praise most; the stitching is perfect and the zippers run smooth.
For walkers and cyclists, this is a standout. One owner walked 10 miles a day in it and stayed dry, and another wore it for a month of rainy commutes, calling it waterproof, breathable, and non-sweaty. The jacket doubles as a windbreaker, the hood rolls into the collar with a helmet flap, and snap-on boot extensions keep your feet dry. It’s medium weight and easy to stash when the sun comes back.
The fit is the honest caveat here. It’s sized for men and runs large — a 5’4″ woman found pants 6″ too long and arms too wide, while a 5’8″ man also found it long. Owners recommend ordering smaller if you’re not tall, and the ankle clasps can snag. One technical buyer wanted a higher 15k rating for the price. For average-to-tall frames who want a breathable three-piece, this is a strong, well-made option.
daily ride: Breathable, well-stitched, and dry through daily walks and downpours.
check height: The cut runs long and wide for men, so women and shorter riders should size down.
6. K.E.J. Golf Rain Suit
The lightweight set that breathes through humid summer rain without the heat.
The K.E.J. is the golf-specific option that earns its place on the trail too. Quality and light weight are the two things owners rave about most — it’s nice and light, keeps you plenty dry, and breathes well enough that you don’t get hot even when the humidity spikes. The jacket and pants store easily in the included bag, which one owner keeps in the car all year round.
While it’s tuned for the golf swing, it pulls double duty as work gear. One buyer uses it for outdoor work across all climates, and another loves the color options — the green version gets compliments. The quick-drying fabric is a real plus for summer storms, and the breathability is the headline feature for anyone who hates the clammy feel of standard rain gear. A summer rain in this suit means staying dry without the sauna effect.
There are two honest caveats. The fit is mixed: some find it just right, but others mention the pants run too long and baggy, and one owner found the jacket tight through the middle. Durability is also a split — one owner hit a seam tear on the pants after the third wear, and another’s shipment arrived with a box-cutter slit. The material also bunches at the front in a putting stance, which can snag a club. It’s a great-feeling suit, just one to inspect on arrival.
golf wear: The breathable, quick-drying build makes summer rain genuinely comfortable.
inspect seams: Fit runs varied and a couple of owners hit durability issues, so check the seams early.
Understanding the Specs
Waterproof Rating (mm H2O)
This number tells you how much water pressure the fabric can hold back before leaking. A 5,000mm rating handles steady rain and is the common baseline for hiking suits. Jump to 10,000mm or even 20,000mm and you’re covered for heavy downpours and sustained storms. The higher the number, the harder the rain it shrugs off.
Breathability (g/m2/24h)
This measures how much sweat vapor escapes in a day. A 5,000g/m2/24hour rating lets a good amount of moisture out, so you stay dry from the inside. Lower numbers trap more heat and sweat, which is fine for short exposures but miserable on a long hike. The best trail suits pair solid waterproofing with breathability you can actually feel.

Final Thoughts: The Verdict

And for a balanced, breathable three-piece that keeps your feet dry, the RainRider is the one to reach for.
