Best Ultralight Rain Jackets of 2026

Some rain jackets are gear. This one is insurance. The Watertight II is the shell to keep folded in the back of the car, in a boat locker, or at the bottom of a daypack, because it packs small enough to forget and works hard enough to justify the space. Nobody plans to get soaked; the point is having something within reach when the sky changes its mind.

It keeps you dry in the rain that actually happens — the sustained, wind-driven kind rather than a passing drizzle — and it does a second job as a windbreaker on cold, dry days. It dries quickly between showers, so a wet morning doesn't mean a damp afternoon, and it rolls up small enough to live in a pack permanently. Of the jackets here, this is the one we recommend to someone who wants a rain jacket and nothing more complicated than that.

Sizing is the usual Columbia story. It runs big through the body and long in the sleeve, so if you're between sizes, take the smaller one; sizing down is what turns a baggy shell into a jacket you'll wear into town. The hood is shaped well enough to stay put in wind without constant tugging, and the zip pockets are the right depth for a phone and keys.

Pull the Antora on over a fleece and you still have room to reach forward, which isn't true of every shell here. The cut is generous through the chest and shoulders and the sizing holds true, so order your normal size and layer underneath rather than sizing up and swimming in it.

In wet weather it behaves like a proper shell. It keeps you dry through steady rain and blocks wind on exposed stretches, and the hand pockets are big enough to swallow gloves and a beanie. Build quality is a step above the budget jackets here: the zip runs cleanly, the seams are tidy, and the fabric holds its shape through repeated wear. It also rolls up small enough for the bottom of a pack.

The thing to understand before you buy is that this is a shell, not a warm jacket. It traps heat while you're moving and gives you nothing while you're standing still, so comfort comes entirely from what you put under it. For a wet commute or a cool-weather hike with a fleece beneath, that's exactly what you want.

Most rain jackets look like rain jackets. This one doesn't, and that was the first thing we noticed: no shine, no stiffness, and a cut that follows the waist instead of ballooning at the chest when the wind picks up. It reads as a normal jacket in a good color, which is why it gets worn on the commute and not just on the trail.

Underneath it's a genuinely well-equipped shell. Underarm vents let hot air out on a climb, the hand pockets and an internal pocket all zip, and the hood and hem adjust so you can cinch everything down when the weather turns properly. It packs into the supplied bag, which is the difference between carrying it and leaving it at home. We rate it the best women's jacket of this group.

Fit is the one place to pay attention. It's roomy through the body, so order your normal size rather than sizing up for layers — the extra room is already there, and one more size turns a jacket into a tent. The sleeves are long enough to cover your wrists when you reach forward, and the Velcro cuffs stop them riding up.

The APEXUP arrives in a package that weighs 8.82 ounces, and the jacket inside rolls into the little sack that comes with it. That's the entire pitch: a shell small enough to live in a bike bag or the bottom of a daypack, dry enough for real rain, and simple enough that you stop thinking about it. For a warm-weather trip where the forecast is a coin toss, this is the one we tuck in.

In moderate showers it kept us dry, which is the honest expectation at this end of the range. What it does have is a hood and cuffs that seal properly in wind-driven rain, decent pockets, and reflectors across the back — more than you expect from a jacket this cheap. Sizing is accurate and roomy enough for a sweatshirt underneath. Ours smelled faintly of the factory when it came out of the sack, and a day hanging outside cleared it.

The reflective print across the back and sleeves is the reason this baleaf made the list. On a dark, wet commute, being seen matters as much as staying dry, and the silver trim catches headlights in a way a black shell never will. The back drops lower than a standard rain jacket too, so it covers you in a riding position and keeps spray off your lower back.

Waterproofing holds up through light and moderate rain, and the pockets are properly sorted: zippered hand pockets plus a slash chest pocket that takes a large phone. The hood is deliberately oversized so it sits over a cap and keeps rain off your face instead of pasting itself to your forehead.

Sizing is the catch. The cut runs slightly small, especially across the shoulders, so order a size up if you plan to layer — that's the difference between a fitted shell and one you can't reach forward in.

Where it makes sense is the commute, the run, the ride: the twenty minutes when you're moving, generating heat, and the jacket is on for a purpose. The chest pocket, the dropped hem, the reflective print — none of it is glamorous, and all of it is right for the weather you're actually out in.

This is more jacket than shell. The Diamond Candy has a lining, some body to the fabric, and enough warmth that you notice the difference on a cold, wet morning when other rain jackets leave you wishing for another layer. It's still light enough to carry in a daypack and rolls up small, but warmth is part of the design rather than a side effect.

The details are thought through. The hood zips off entirely, the cuffs adjust, and the front pockets are big and zippered. Water beads and runs off rather than soaking in, and the fabric comes out of a bag without a wrinkle — rolled up, it fits in an airplane seat pocket, which is the sort of thing that decides whether a travel jacket gets used.

Fit is where you need to plan. It runs small through the chest and hips, and the cut is structured enough that it won't stretch to accommodate, so go up a size if you're between sizes or want a sweater underneath. For shoulder-season travel and cold mornings, that extra warmth saves you packing a fleece.

A pullover is a deliberate choice, and the right one for some trips. There's no full-length zip to leak or snag and nothing to fumble with wet hands; the jacket pulls on over a base layer in one motion. The trade-off is that it comes off over your head too, which is worth thinking about if you'll be adding and shedding layers all day.

The packing trick is the center pocket, which doubles as the stuff sack — the jacket folds back into itself and disappears into a glovebox or a tackle box. Two separate hand pockets mean you're not sharing one kangaroo pouch with yourself, and they sit where your hands naturally fall.

In rain it does the job. The hood cinches down tight around the face and neck, which is the part inexpensive shells usually get wrong, and the fabric keeps water out through steady rain. It's thin, though, and the seams are the place to keep an eye on: this reads as a jacket for a couple of seasons of hard use rather than a long-term investment.

Where it earns its place is the bag you already carry — the tackle box, the golf bag, the commuter pack. It's the shell that's there when the sky opens and asks for no space and no care in between. That's a modest job, and it's the only jacket here that does it without a full-length zip to think about.
