Sizing Notes
Measurements are stated in inches unless otherwise indicated. Size chart values represent body measurements, not garment measurements.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
Inseam is measured to the floor.

Very solid features & quality

Slept on jacket. Maybe overpriced at retail? But maybe not… Features I like in a backpacking rain jacket, not in order: water protection, ventilation, durability, and lightweight. First, REI does not publish HH figures for their proprietary membrane but it does the job. You’ll find pit zips, hem cinch, and hook-and-loop closures at the wrist. And an 11 ounce weight for a 3-layer jacket is awesome!
The Flash Air jacket is well-designed : The face material is UHMWPE Spectra (why doesn’t REI list this in the specs? Many qualities similar to Dyneema, including high strength and low water absorption.). Nice surprise because this is an awesome durable and lightweight fabric that is UV-resistant. All seams look to be welded and taped. Zippers appear to be YKK Aquaguard to minimize water entry without storm flaps to add weight. Internal chest pocket. Hood is adjustable and *not* helmet compatible which means it actually fits when hiking. Decent peripheral vision.
A medium is roomy in the chest for me at 6’ and 150 pounds. Room to layer for summits and chilly evenings. I could maybe wear a small but prefer the slightly longer body (good coverage at 30”) and sleeves.

Great weight, terrible fit
Säsquatsch2 years ago
Just received my Flash Air jacket in Copper Spice, size Men's Large. The jacket looks great, is an authentic 3-layer, and is lighter weight than my previous eVent-based jackets.
Construction seems reasonable for such a lightweight jacket, with aqua-guard-type front and pocket zippers. Front zipper has a conveniently sized pull that will work with gloves or maybe even hot-dog-fingers. Only concern in this area is that the pockets all have bellows at the bottoms, and the only thing holding the corners down are small round patches of adhesive-backed liner fabric (visible in the close-up photo of the interior chest pocket). I'd prefer vertical bellows in the center of the pocket with all sides or the pocket entirely affixed to the jacket liner layer.
But the fit ... OMG, it's 4-person tent! The size chart reads a chest measurement of 42-45 inches for size L, and this jacket measured at least 50 inches zipper to zipper under the arms. It's 50 inches around at the bottom hem as well. My old REI Kimtah eVent jacket in Men's L was not nearly as baggy or oversized---it was a proper fit.
The hood is likely supposed to be helmet-compatible. It would probably work for Hagrid's helmet of hair as well ... quite large and floppy, and the elasticized cord adjustment in the rear of the hood seems overly long---pulling it out 6 inches from the cord-lock makes no adjustment to the hood.
Recommend strongly considering sizing down.

Excellent hard-shell
2 years ago
I bought this last week and then spent a rainy, cold weekend in the snow, fog, mist and rain, and it served me very well. I kept dry even though I was in near-constant drizzle for 12 hours or more. I did get a little sweaty when I hiked in, as I tend to do, but I didn’t use the pit zips which would have undoubtedly helped - but I’m not used to using them yet. The hipbelt-compatible pockets are nice, very roomy; the inside pocket, however is too small for my phone. It’s definitely lightweight compared to other hard shells, but hopefully the fabric will hold too well to use. We shall see!

So tired of looking for a rain jacket that isn't
1 year ago
My own personal disclaimer, I am so tired of rain jackets that are not close to water resistant. I'm not even expecting waterproof anymore. Bottom line, after a hike near Aviemore, Scotland with light snow most of the day, I unzipped my REI Flash Air jacket and was stunned to find my under layer wet all down the zip and pockets at the bottom. This is a basic fail for me.

A good rain jacket, protected in torrential rain
7 months ago
I bought this REI jacket in February 2024 before taking a trip to Ireland in May. The jacket seems to be good quality overall and does its job of rain protection. I usually find my shirt is sweated when I wear this (and most other 3 part rain jackets) so I generally don’t expect the breathability performance to be good. I generally hike with the pit zips open to help with ventilation and this helps but doesn’t cure the sweat issue. Like other reviews the chest pocket is a bit small, my cell phone is a “mini” version and it just fits. My only complaint is now one of durability, when I last used the pit zips one of the zippers failed and I will be returning the jacket and swapping it out for a hopefully same product. In about 25 years of REI purchases I think this is the first one I’m returning, I have returned boots to the manufacturer for faults but I haven’t done this with REI brands.

Lightweight and breathable; great for hiking
2 years ago
This is a great rain jacket for those places where the rain falls regularly, and it is humid and warm. It is a lightweight and breathable jacket that effectively sheds off that heavy rainfall while allowing you to ventilate in the armpit areas. I just returned from a ten-day Costa Rica trip during the rainy season, and I was very happy with this jacket's performance.

Hiked in rain, got wet chest.
1 year ago
I've had this for a month and finally gave it a serious test, hiking for an hour in steady rain up in the Adirondacks. The material and zipper seem to be very good and I was comfortable the entire time, but when I came home discovered that my upper chest was wet and so had to change clothes. For my money, you should not have to change clothes after being in the rain with a good rain jacket. I don't know if the design allowed rain to get through the neck area or it seeped through the material, but it hardly matters. Wet is wet. It will be returned.

Best One For Me

I was planning on buying an Outdoor Research Foray II Gore-Tex jacket because of all the stellar reviews but when I tried it on at REI, there was no room for layering. Then I tried some of the other brands (Rab, Arc’teryx, Patagonia) but they were even more snug fitting. I’m not an athlete but I’m not overweight either (5’8” 160 lbs.). One salesman suggested I try on the new Flash Air. It fit perfectly while leaving room for a fleece liner. I bought The North Face Summit FUTUREFLEECE Full-Zip Hoodie. It fits great under the rain jacket. There’s plenty of armpit ventilation and the fabric pattern is attractive. Also, the Foray II is only 2-layers whereas the Flash Air is a 3-layer laminate, making it more durable. I’ve had it for a couple months and haven’t been in any downpours yet but I think it’s safe to assume it’s up to the task.

Not that waterproof
1 year ago
The Jacket seemed to be well made, but upon testing it for short periods in the rain, it wetted out very quickly and felt damp inside. It’s not a jacket I’m going to trust on a backpacking trip or day hike. It just doesn’t seem as waterproof as advertised.

Worthless in the Rain.
1 year ago
The following occurred the Antietam NPS campsite. Looking for cell service in a persistent drizzle, my new REI “waterproof” windbreaker wetted through, soaking my down jacket, wool mittens (in the jacket's pockets), wool long-sleeve base layer shirt, wool boxers, everything. Hypothermia set in. I lost feeling and all dexterity in my hands. After peeing in the brush, I couldn't re-zip the outer hard shell jacket, down jacket, or re-tie my track pants' drawstring. Note : 1. Had I remained in my tent for the day, waiting for the rain to pass, none of the above would have occurred. 2. Had I been caught out, trekking the 5-10 often deserted, very remote miles between campsites, I might have been in serious trouble.

Good looking jacket, TBD if it stays waterproof
2 years ago
The REI xerodry gtx jacket did not stay waterproof after the first several uses, so I decided to give this substantially more expensive jacket a try even though it uses a REI brand membrane which probably isn't as good as gore-tex. I am hoping the 3 layer upgrade will keep it waterproof. The negatives of the jacket are that the inside pocket is too small for most phones and the pit zips only have one zipper going one way, not two, so it's pretty much all or nothing. Also when closed the pit zips slightly dig into the armpit because of the articulated fit of the arms. With many brands like patagonia I am in between a small and a medium, often making the small no good for layering and the medium with space for an extra stomach. At 5'7'' 150lbs, this small fits perfect on me with enough with room to layer underneath, but not so much that it would look weird without a thick layer. As I love the fit, now I gotta cross my fingers the waterproofing holds up.
