A Y2K Mountaineering Legend, Reborn for Range Days, and every day.
The modern outdoor industry forgot how to make reversible gear. Somewhere along the line, designers decided you need a hyper-specific, fragile micro-layer for every minor shift in the weather. We miss the days when your gear did the heavy lifting without a 12-step layering manual.
Reversible clothing has deep military roots, dating back to mid-century bomber jackets that flipped inside out for emergency visibility and dual-camo ponchos. By the late 20th century, the invention of synthetic pile fleece completely changed cold-weather survival. The 1990s gave us the holy grail of Y2K outerwear: the reversible fleece pullover. It was the ultimate 2-in-1 garment for climbers, hikers, and soldiers who wanted to carry one piece of gear instead of two. Then, the trend simply sputtered out as the market became obsessed with "mission-specific" garments.
Some call reversible gear a novelty. We call it PEAK efficiency.
The KSGI Reversible Fleece brings back the versatile, rugged charm of classic mountaineering layers. We combined vintage outdoor aesthetics with modern tactical utility to create the only mid-layer you need to pack.
Flip it to the weather-resistant woven nylon side to block biting winds and shed light precipitation. When the temperature plummets and you need serious insulation, reverse it to the soft synthetic fleece side to trap body heat like a furnace. It provides two distinct, highly effective functional states stitched into one bombproof package.
Right now, we are running these in classic Olive and Coyote. Because really, that covers about 90% of end users and any of the autistic patterns they may want to pair it up with. Looking at you, Greek Lizard guy.
So whats inside? (or outside?) It's A tough, weather-resistant woven nylon shell on one side, and a dense, heat-trapping synthetic fleece on the other. Friggin’ cool on both sides. Inspired by the golden era of ‘90s outdoor gear, but engineered to survive the abuse of modern tactical environments and your in-laws’ basement. It almost Completely eliminates the need to carry a separate windbreaker and fleece whether you can't decide, or your inner eagle scout is telling you "Always be prepared" with that stutter you thought you got rid of in the 7th grade.
You do not need a closet full of fragile, overly complicated jackets. You need gear that adapts to the environment on the fly. Stop carrying extra weight and secure your KSGI Reversible Fleece today.

Sizing
Pick your usual US sizing. It's a more "Retro" fit so expect it to fit like a comfy relaxed fit hoodie - perfect for throwing on over a base layer or tee shirt. Much like our other KSGI items it'll be a bit baggy when you order your size, so if you're on the slimmer end you can size down if you'd really like to.
They don’t know my jacket is actually two jackets...
On the Olive Drab & Coyote Solid Color models, we used an anorak style pocket, while the camo fleeces use a passthrough zipped pouch.
The advantage of the pouch is that it stays as one pocket whether you're wearing the camo side out or the fleece side out!
The non anorak version also adds the classic chest pocket seen on some other Y2K era reversible fleeces for small items like your wallet or pack 'o luckies.
KSGI Reversible Fleece Jacket
Far from a gimmick of fashion, Reversibles have had a firm place in military environments since the early 20th century with reversible camouflage uniforms and blaze-orange lined "Bomber" jackets.
As the outdoor industry blossomed from adapting military garments into a more civilian friendly use case from WW2 onwards, the innovations and ideas actually became rather simultaneous, with military garments taking outdoor industry ideas and adapting them for combat, and combat clothiers switching gears to take their innovations to the fashion world.
With the explosion of technical apparel & gear that the 80s and 90s brought, companies like The North Face, Patagonia, and Columbia came out swinging with advanced patterns and even more advanced materials.
Many of the breakthroughs were in the synthetics, which gave birth to low cost, high performance garments for the everyman explorer & tier one soldier alike. Low pile fleeces dominated the market as the perfect goldilocks layers whether they were on the ski slopes or the mountainsides of afghanistan.
That certainly was a major source of our inspiration...
The nature of the reversible fleece is that it can be worn how you want, when you want, and wont take up the space that two traditional layers would.
Weather-resistant nylon ripstop on one side with the fleece inside could keep you protected from harsher conditions, and fleece on the outside works as an incredible windstopper and showstopper.
In a magical time where recreation and reccenoitering had more in common than not, we think ideas like these are what make that era full of "timeless" gear.
KSGI is made for fans of NATO kit that just keeps working, whether you're snuffing out insurgencies in caves or playing war in the sandbox...
It's not the gear that makes the operator, it's the stories of those operators that makes the gear legendary.
Great jacket! I wear an XL normally but after reading reviews about sizing I ordered the 2XL and its a perfect fit. Definitely reccomend this and reccomend sizing up.
I have no top on my jeep so I freeze to death during the morning. This fleece is pretty good at insulating and keeping wind out. My only critique is that I wish the pocket openings were a bit wider so I could draw my full sized pistol from my pants. (This would be possible because of the double zippers.
PROS
This pullover does an excellent job on a cold and windy day. I've been wearing it around for a couple of weeks and have used both sides of the pullover. It is comfortable and easy to clean. I let mine air dry outside after a cold wash and it was ready to go in about an hour and a half when left in the sun. I got a medium, and outside of the arms, its got a slightly more baggy feel to it. Its a solid piece of gear for the price.
CONS
The zippers are a little finicky; they are prone to getting stuck if not pulled a certain way. I got the coyote brown pullover, and I don't really have any real use for the kangaroo pouch on the nylon side. I'd much prefer the pocket layout seen with the flactarn and UCP styles. The arms are tight, too tight to really roll or push up the sleeves. I have a medium buildand bought a medium, so I'd advise going up a size if you want more space in the arms.
Solid item, I am 6ft 180lbs and the Large fits great with a bit of room for layering.
Being an owner of the layers this inspired, I cannot recommend this enough. The only time I remove it is to wash it. And I haven’t washed it yet.
