 With Mythic, we think we've really taken a step ahead compared to the other things that are available so far. It's quite a challenging project because we basically had to start again from the first principles. There's fabric selection, the down selection, and then designing the product so that it was the most efficient design possible. And in some cases what we've done there, without giving away too many trade secrets, we've basically reformatted the way that you construct down chambers and the way you balance the correct amount of down in each area. And so it was quite a challenging project, although it's based on stuff we do anyway, it's just taking it all up to the next level. So all our sleeper bags are hand-filled here in Derbyshire. We've got a really talented team of guys, some of whom have been working here for decades and they know exactly how to put together the very best sleeping bags. And what you'll see is that each chamber or each tiny section of the bag has its own fill-weight chart and each section of down is meticulously weighed out and then pumped into each chamber bit by bit. You'll see on Mythic that the chamber shape is like a chevron, like this section, and we arrived at that design through process of trial and error and we think that having that shape means that the down is better controlled within each chamber, both this way and this way, and that means we can use the optimum amount of down without overloading each chamber so you get the lightest possible weight and the maximum warmth. The outer fabric is a Pertex fabric, it's in their Quantum Series but it's exceptionally light, it's the only seven denier fabric they do and the denier is the count of the fibers that go into the yarns, it's super light. And that comes down to about 21 grams a square meter and seven denier is about as light as is possible to go and still have robustness and strength. The other thing about ultralight gear is that often people will take out features that you actually need in order to save weight and we've made sure we don't. For example the shoulder baffle inside the bag which is essential in our view for trapping warmth when you're sleeping cold and that will tighten up around the neck inside the bag and we've done a something different there which is an ergonomic shape so it falls to the same shape as the back of your neck and around the front so it fits perfectly when it's adjusted tight to keep you warm. So I think the thing that's important about Mythic for me is that if you look about the history of Rab, Rab Carrington started by making sleeping bags and we're kind of proud to carry on with that thing that started this whole business and this whole brand and sleeping bags remain at the heart of what we do and Mythic really for us is a good example of where the future lies.
