In reply to Gazlynn:
We’ve just seen this thread and thought it was worth addressing a couple of the points raised.
The Tupilak and Alpha SV both use an 80 denier face fabric which have extremely similar performance characteristics [as well as looking very similar under magnification!]. Some of the comments on here are correct, not all similar fabrics are always the same in terms of actual performance and, like most brands, we use a variety of different fabrics depending on the product and its intended use. It is not true that any particular brand necessarily has early access to face-fabrics or laminates. Some technologies may be trialled first with individual brands but many others are not. As an example Mountain Equipment was one of only two brands in the world to first launch Gore-Tex Pro to the market. We should also add that we are one of the few worldwide R&D partners for Gore-Tex fabrics and spend considerable joint resource in developing and testing both laminates and face fabrics.
A huge amount of testing has shown the 80 denier face we now use throughout the Tupilak (a revision for AW15) is equal to anything out there for its intended use. This said, tougher fabrics are available with the 150 denier face fabric we use in our MRT jacket being a great example. This is virtually bomb proof, and looks fantastic under magnification, but wouldn't necessarily be considered ideal for a dedicated climbing jacket if you wanted maximum mobility and reasonable weight. Despite all this denier is just an aspect of a face-fabric’s actual performance and should not necessarily be the sole consideration when weighing up the suitability of a given fabric.
Finally, I think it was noted above but the hood on the Tupilak is significantly different to that found on our Changabang Jacket. It is not only larger overall but made up from an entirely different 3-dimensional pattern. It fits over and works with climbing helmets better than any other.
