Well worth it!!!
I bought my Tronic since my old Burton jacket was out of date in every way. I took is out on the slopes and the results were exactly as expected. It performed will in keeping me warm, it kept out the snow when purposefully sliding down a hill, and the functionality was superb.
The only faulty feature (which can easily just be pushed aside) are the thumb loops. They are very rigid, and although my arms are not too long for the sleeve, when I put my thumb through the loop, my arms become limited, and feel uncomfortable. Even with that problem, for the price, I couldn't ask for a better jacket.
