Warm and slick Review by Sandy

Sandy 4/8/2015

This is a great layering piece. The outer material is very slick and slides under your gore two shell with no binding like you get from fleece. The insulation is good, really good. I haven't had the chance to test the claims that is retains 96% heat while wet because I'm pretty careful about having my rain smell ready at the first hint of rain.

It fits pretty true to size with a fit on the slimmer side. I wouldn't expect to put much more than a thick base layer beneath it, but I would not thing you would need too much.

The stretchier material under the arms really does work, I would say one of the best things about the jacket is the absolute freedom of movement. No restrictions on movement at all,m very comfortable.

My lost stars are due to the fact that it is made in China instead of Montana. I'm worried Simms is going to start making all of their gear in China and then the quality will slips like many other brands. Simms has a premium price m

Great jacket but has fallen apart a bit Review by Scott

Scott 3/19/2015

Being a huge fan if Simms I was so excited to purchase this jacket. It's the perfect fall jacket up here in Michigan. If I recall I bought this jacket in September and by January the pocket zipper has broken on right side as well as the Simms logo on upper left chest has been peeling off. All in all another great product from Simms. I don't think there's a day that goes by when I don't have some sort of Simms clothing on....

warm, light weight and packable Review by Sierraguide

Sierraguide 3/6/2015

A great jacket for walk and wade or rowing the boat. It's not to heavy or bulky but it keeps you warm. Works out great with a rain jacket over it for real bad weather.

Not that great Review by GL

GL 2/8/2015

I really wanted to like this jacket but it continues to disappoint. The inside of the pocket which is a double layer of thin fabric blew out somehow after the first few times in use (fishing), the zippers on the pockets constantly snag the jacket when trying to close and the cuffs on the arms which are a stretchy fleece are too thick, bunch up and have stretched out with only maybe a dozen days wear. :(

Good All fishing Jacket Review by Ben Sierra Guide

Ben Sierra Guide 12/29/2014

Weatehr can be unpredictable here int eh Eastern Sierras of California. You might wake up to a 7º morning and be fishing in 60º by noon.
Throw on a Simms Solarflex baselayer, and this coat, and you'll be good all day.

It is light weight, compressible, and is comfortable iin a wide range of weather conditions. Great for backpacking, skiing, and of course washing your flies.

Perfect! Review by Somoza

Somoza 12/20/2014

Perfect in the Field Review by Craig Schuhmann, Guided Waters Fly Fishing

Craig Schuhmann, Guided Waters Fly Fishing 12/16/2014

Balancing insulation, layers and outwear can be a tough and frustrating. The kinetic has thus far gone a long way to solving this problem. With minimal layering, Insulation and breathability seem just right in a 30 degree wind or 50 degree sunny day, and all variables in between, including light rain. You will still need a shell in a downpour. The fit, stretchy panels, and sleeve length did not make much sense to me in the store, even feeling a bit constrictive, but once in the field this jacket literally molds to your body and moves perfectly with every action whether casting, rowing or scrambling over rocks. The kinetic layers nicely under a pair of waders with almost no additional bulk. When worn, the hood is lightweight, barely noticeable and the edges stay out of your field of view, all while adding significant warmth. This is not a coat for walking down Main Street, but on the river it’s one sweet piece.

Good jacket Review by Robert

Robert 11/27/2014

The kinetic overall is a great jacket, the only issue I have with it are the zippers for the pockets. The left zipper failed after about a week of use. It's great for layering and how lightweight it is is awesome!

The Jacket That Does It All Review by Nate Sipple

Nate Sipple 10/15/2014

This is the jacket I've been waiting for Simms to make for a long time! Simply put, this thing rocks! Worn alone or under a shell, the Kinetic will keep you warm while letting your core breath. The stretch fabric under the arms and along the cuffs is smart as it will hold up longer/better than the nylon material. The hood is perfect for blustery fall/winter days and the zippered chest pocket is great for a phone, tippet, etc. It is a slimmer cut, which I like, so keep that in mind when ordering I'm 6'2", 210 pounds and the large is great. If you plan on layering a lot underneath, order up a size! Truly a great jacket... Looking forward to other colors in the future!
