Better than a mammut eigerjoch pro? - Montane Deep Heat Jacket - Men's

I bought a Eigerjoch Pro from Mammut wanting a supremely, over the top alpine jacket, even though living in Dallas, Texas there is probably no need for it. But loved the jacket. Then saw this Montane Deep Heat on sale on a website and thought I would give it a try. WOW! I couldn’t of been more happier of the decision I made. This jacket has the same Pertex Quantum Pro, Diamond Fuse technology, for a third of the price of the Mammut ($600). Not to mention the 800+ down fill, compared to the Eigerjoch 850. But the warmth was just the same. I think I am a sold customer for life on Montane products, and glad to have found them.
