Love this jacket! Review by Salvatore
Let me begin by explaining that this jacket is not JUST a fishing jacket. I test gear for GORE, but this has become my "go to" jacket during the cold weather season, PERIOD. I wear it to work every day in the winter, and wear it on the water every day while fishing in the fall/winter/spring when the weather is cold. This jacket is comparable to the "big name brand" jackets that cost way more than this, and don't offer the protection, or specialization for fishing that this does.

I wore this steelheading this past winter, the jacket kept me plenty warm and provided me more than enough flexibility while swinging flies and chasing chrome!

The snow/rain would just bead up and roll of the jacket, I never felt wet or damp.

The jacket fits close to the body, I think this is a positive attribute for this specific jacket as layering isn't needed, and it demonstrates Simms taking into account the "fishermens" needs while constructing this jacket. No bulk to snag your lines like other jackets.

Plenty warm, this insulation is fantastic, pockets are perfect and warm your fingers on those chilly mornings.

Once the sun comes out and it heats up, i am able to pack the jacket down into my sling pack and fish until it gets chilly again.

Love this jacket.
