Klim Inferno Jacket 4.4 5 8 8
Nice jacket to have I got this for those cold days when I need to stay warm on and off the bike and it's a great jacket. It's made with form and function in mind and not style, so it does the job well but you won't be the fashion czar wearing it. But that's not the point. It's light and easy to carry around, fits well- I wear large, 5, 11" and 195ish pounds (well carried I might add). It's a great choice. I thought it was a little steep price-wise so I checked out apparel stores and came right back- yup, even Under Armour didn't have anything close. June 22, 2015
Love this jacket so much I bought two. Great base layer jacket, I bought two. One black and one grey. It's a great base layer under my Klim Lattitude jacket. A couple minor annoyances with it though. 1 It's a magnet for dog hair. If don't have two furry mutts then that won't be a problem. 2 The raised logo on the left collar causes the collar to fold in and poke you in the neck all the time. Annoying unless you have it zipped all the way up. Looking into removing that logo. Because of annoyances 1 and 2 I give it an overall 3 out of 5. April 8, 2015
Excellent lightweight jacket I like Klim products. I own an older Klim Inferno in black, and I wear it all the time. I decided to buy a new Inferno jacket in the lighter gray color, as the zipper pull on my old jacket broke after 5 years of wear. The new jacket fits smaller than the old one. I am 6'4", 225lbs and have a 26/27" arm length. I originally ordered the Inferno in Large, to match my old one, but it was too tight. I sent it back to RevZilla and they immediately shipped me an XL which seems to fit fine. The new style Inferno also has zippered pockets for your hands, which is a nice touch. All in all, a great jacket, and very durable. February 2, 2015
Excellent mid-layer The Latitude jacket doesn't come with a liner, so I needed something to bridge the gap between warm enough with no liner, and cold enough to need the electric liner. The Inferno is a mid-layer, not really outerwear. A Large fits my 6'2", 205 pound body perfectly....That is, snugly over a base layer. The shell doesn't really seem durable enough to wear without something over it, and it's certainly not making any effort to be stylish. That's fine with me. For a relatively thin layer, it does a good job of blocking the wind and keeping you warm. No issues with cold running at highway speeds in the upper-50s with a t-shirt under and the Latitude Misano over. December 22, 2014
Great mid- layer. This is my second inferno jacket. Durability stands out as does mid layer warmth. I wear this jacket all fall, winter and spring. October 6, 2014
Perfect Mid-Layer Paired with the Inferno pants these turn cold days Miami. No binding, total comfort, and great breathability when paired with an appropriate base layer and Goretex outer. Materials, workmanship, and overall quality are all excellent. It's also a great destination jacket. Haven't experienced ANY pilling as was mentioned in the previous review. Makes me wonder if it's being worn against something it's not suited to. In my experience, KLIM infallibly produces their mid layers to glide freely over their base layers and also under their Goretex outers. April 14, 2014
Product Fabric I bought a black Inferno jacket back in December 2013 and am not happy with the way fabic is "pilling" in the front and sleves of the jacket. Jacket for me, is a light use garment,, weekends only. I have written to Klim twice about the issue and have not recieved a reply. Not a fan. March 12, 2014
Klim Inferno How ironic is it that I lost all my riding gear last summer to a forest fire and one of the first pieces I replace is called Inferno. I had several Klim jackets, purchased and received through donations to the Riff Raff. I keep coming back because it is a great product. February 3, 2014

A shopper asked: does this jacket have the elastic cinch strings around the waist to adjust at the bottom? Sep 17, 2014

Douglas C: No, mine does not have a waist cinch string around the waist. I purchased my Inferno Jacket to wear as a mid-layer under my Klim Latitude Masano outer jacket so sealing at the waist was not a concern for me.

If you are looking for a light to mid-weight jacket to wear on the bike as an outer shell then I would suggest looking at something from North Face that has Sleeve Cuff closures and Waist Cinch strings.
