Gore Bike Wear's Fusion Tool SO Jacket functions as either a single layer defense against cold weather on the bike, or as a casual jacket about town. Regardless of how you use it, the secret to its versatility is the Gore WindStopper Soft Shell fabric. In an overcrowded market of purpose-specific clothing, it's nice to know that you have something that works perfectly on the bike, and lets you blend in with the civilians when you're on foot.

Gore's Fusion Tool is looser fitting than its Xenon SO jacket, however, it still won't flap in the breeze. In fact, Gore still considers it a slim-fit jacket. But, even with the close fit, the Soft Shell still stretches and moves with your body. So, even if you layer underneath, you won't feel bound by the fabric. The sleeves are pre-articulated in order to accommodate a natural, relaxed bend at the elbows, and the tall fleece-lined collar keeps the elements from entering up top.

Due to the effectiveness of the WindStopper membrane, Gore has included zippered vents under the arms in order to give you the ability to moderate your temperature. Perhaps the only details that give the Fusion Tool jacket away as a cycling piece are the standard three pockets on the back. The outer two are angled down towards the outsides for easier access to your riding essentials from the saddle. There's also a zippered Napoleon pocket on the left breast and small cloth for cleaning your eyewear. The tail is cut a tad longer in order to accommodate your position on the bike, and the lower hem and sleeve cuffs are bound with a simple and comfortable Lycra band. Reflective elements on the shoulders, back, and forearms will also increase your visibility to motorists in low-light conditions.

The Gore Bike Wear Fusion Tool SO Jacket is available in five sizes from Small to XX-Large and in the colors Black/graphite grey, Neon Yellow/black, and Varsity Green/black.

Here's what others have to say...


Perfect for winter fat biking

  • Familiarity:I've used it several times
  • Fit:True to size

I wore this all winter out on my bike in the snow, usually with just a base layer. I'm 5'10", about 200lbs. It's probably too warm for anything above freezing, but I was thrilled every time I put this on for a ride. Was stretchy and breathable and comfortable, and perfect.

Based on some of the other reviews, I was worried it wouldn't fit correctly, but all was well.


Great quality, felt warm but fit loose.

  • Familiarity:I returned this product before using it
  • Fit:Runs large

I had to return this one. I already have a Gore jacket and a vest both in size L (possibly slim fit) that fits great. The Large in this one was way to big with a lot of loose clothing. I was looking for something warm but with a more adjusted fit, this is not the one. I'm 5'8" 165.


Nice long sleeves for this Mtn biker.

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:Runs small

The other guys left very similar comments to my own, so here's my take on size.

I'm a tall, lanky guy = long arms. 6'1" and normally Large ends up with too short of sleeve. I chose the XL and it's great on sleeve length and the body has room for some winter layering, but I rode with a tshirt today and it was fine, not too bulky. I didn't even cinch up the hem cord. Loved the vents.

Very happy, but crazy confused with the left handed zipper.


Good deal.

  • Familiarity:I've used it once or twice and have initial impressions

I've used the original Gore Tool jacket since 2010. Got clipped by a car last February and the jacket got torn. Thus, I decided to buy the Fusion Tool SO. Not as warm as original Gore Tool jacket but pretty close. Zips seem to work better, and I like the tethered sunglass cleaning cloth in the chest pocket. Steeper angled rear pockets with the added zips are cool. It gets chilly during the winters here in the Northeast US, so I'll probably have to add some clothing to my core & arms to equal the comfort of the original Tool jacket. Overall I'm happy I bought it.

......a few days later.....I've worn this jacket on 2 more rides and really like it, BUT it just continues to feel a size too large, and thus chillier in 30° temps than I would expect. Other reviewers complained it ran too small, so I am a bit perplexed.

Anyway, I finally decided to look into an exchange, and the fine folks at CC came thru in flying colors. What a great place to do business! Thanks guys!

Looking fw to getting it in small.


Gore Fusion Tool SO

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:Runs small

For the uninitiated, picking out winter gear can be a daunting process. I spent countless hours researching different companies, technologies, materials, layering name it. What helped me most though were the reviews, so...

The very first day I rode in this it was 25F and windy as hell. You know when you check the weather on your phone and it has the little wind gust symbol? Yeah, that kind of windy. One gust nearly pushed me into traffic. (I commute into Manhattan and ride in the outer burroughs). The wind on the Queensboro bridge can be pretty severe. Needless to say this thing performed beautifully. Now, being a stranger to winter cycling gear my first impression was, 'There's no way something this thin is going to keep me warm.' (We New Yorkers are accustomed to bundling, often to the point of resembling walking coat racks.) Well I'm happy to say I was wrong about that. This jacket did the trick. I wasn't heavily layered either, just a very thin Gore short-sleeved T (worn exclusively for wicking), and a Mavic long-sleeve Wool base layer. The jacket over that. Only 3 layers and one that was uber thin. I also have a jersey but I can't see having to wear it unless it was closer to 20F or into the teens. So, low temps, high winds, no problem.

The fit is small. I'm 5'10" and 150 soaking wet and I went with a large. I don't like my clothing super tight but the deciding factor was the ability to put on a jersey underneath if need be. I originally ordered a Medium and it was simply too tight for my liking. Zippers are smooth and back pockets are well placed. Zip-up neck is comfortable and not annoying. The sleeves on the medium were perfect. Sleeves on the large were just a tad long but it's no big concern as they have a quality elasticity.

Over all great product. When or if I buy another jacket it will be a Gore.



  • Familiarity:I gave it as a gift but have feedback to share

Fusion Rocks (I am told!). Warm, windproof, comfortable, functional. Rode in 40F with 30mph winds, and was warm, didn't feel any wind.

Zips were a little difficult to operate (without gloves!). Pockets are generous in size, and placed sensibly on the jacket.

Could use more reflective elements, especially for roadies.

Gore normally runs small, so he chose a 'XL' for a 5'9" 185lb frame. Fit described by Gore as a "Comfort Fit"...could maybe have worked a 'L' instead. But this gives room for layering...a Great Mtn. bike jacket. For you 'roadies', suggest ordering according to chart...don't size up with this one.

Pit Zip's the Sh!t!

Fantastic venting, both under arm (which goes almost down to the rib area!) All zips have this open mesh behind for additional venting as needed.

Pit Zip's the Sh!t!


Great, ample pockets that are easily accessible. Fairly good reflective hits...could have used more (like the Xenon line up has).


Worth It

Pictured here with Gore's Fusion 2.0 Windstopper Soft Shell Pants. Excellent Combo.

Size here is a XL on a 5'9" frame. Fit describes as "Comfort" by Gore. Usually Gore's tends to run small, but in this instance, a 'L' may have worked. The 'XL' leaves room for layering and movement...fine for mtn biking.

Worth It

Exceeds expectations

  • Familiarity:I've put it through the wringer
  • Fit:True to size

We are just completing a beast of a winter here in ND, and I have been commuting by bicycle. Awhile back On a training ride, I made a layering mistake that I didn't notice until I turned around to ride 15 miles into a cold north headwind. I was sweating and the wind instantly went to work. I felt lucky to get home and immediately went looking for a way to prevent this from happening ever again. I am frugal and often skeptical of the prices demanded for so-called performance clothing. Well, I shelled out the money and now a couple of months of daily rides and use later, I think this Gore Bike Wear jacket is the best money I ever spent. It has great venting for adjusting to conditions. It stops the wind in its tracks. With the right combo of merino t-shirt and micro fleece, I can wear it down to 5 degrees and still be comfortable. After mountain biking, the dirt and mud splatters on the outside wipe off easily. It is magic in terms of resisting odor. I found the size fit true: I got a Medium and I am 5'10, 155lb. It conforms well to my body when I just have a t-shirt underneath but allows for more layers if I need them. Great pocket locations, too. In a world where I am too often disappointed with what I get for my money, this is one garment that makes me smile every time I reach for it and that will no doubt standup over the long haul.


Excellent Jacket

  • Gender:Male
  • Familiarity:I've used it several times
  • Fit:True to size

This is the first year I have decided to go MTB also in winter. I had one windstopper Jacket that I used and I was a bit cold.

So I bought this one.

I liked it a lot from the moment I received it. The craftsmanship is really great. the colour (I have the green) is quite nice.

It really fits nice.

I used it several times but because winter was very warm in Austria I did not want to hurry with my review before a real test.

Last week-end it was cold at -10C (14F) and I went out using it. I had a Icebreaker first layer and one tricot underneath.

Going up I could really feel I get very warm. Going down at about 35 - 40k/h I was amazed by how warm I was feeling my body. My hands and my face were cold, but the jacket was really protecting me from the cold wind.

When going out at 0C to 7C I take it off when climbing and put it back on when going downhill

Highly recommended!


Fantastic, Very Warm Biking Jacket

  • Familiarity:I've used it several times
  • Fit:Runs small

Excellent jacket, nice and slim fit. I could fit into a medium (6'0" 175lbs) but it was very snug and I bought this for cold, nasty winter conditions so I bought the large. Extremely warm, doesn't let wind in, you heat up quickly as you are riding. Wouldn't recommend for over 40F days. I ride it with an underarmour winter thermal under layer and you are perfectly temperatured.
