The Bastion Jacket from M.E. is a lightweight hooded jacket that can be thrown on to provide you with warmth & a 100% windproof barrier. This is thanks to the Gore- Windstopper shell fabric that stops the wind from pushing out warm air trapped within the Polarloft Duo insulation. This brilliant jacket is probably one of the best lightweight insulated jackets around today; its warm, extremely breathable & very very weather resistant. Chuck the Bastion on over a good base layer & its pretty much all youll need for winter mountain activities & thanks to the highly breathable face fabric & insulation the Bastion works extremely well as a mid layer for extreme conditions. The Windstopper shell fabric, apart from being rather obviously windproof, is highly water resistant, so youll only need a waterproof shell when the weather gets extremely nasty. Stretch Windstopper panels under the arms & down the sides provide superb freedom of movement & ensure an efficient fit to maximise the insulation. The bastion is filled with a synthetic insulation called Polarloft Duo which is made up from a mix of hollow core & multi-channel fibre. These fibres work together regulating temperature as you move. It provides impressive moisture management which aids the removal of excess heat & moisture when you are active yet it does an amazing job of keeping you warm during rest periods. Unlike Down, Polarloft Duo will retain a high percentage of its warmth even when wet, & will dry out exceptionally quickly, making the Bastion Jacket absolutely perfect for UK winter conditions. The Bastion Jacket has a Mountain style Helmet Compatible (HC) Hood & has been cut to M.E. Alpine Fit block. This means the jacket has a closer fit than normal creating less dead space making it more thermally efficient, but don’t worry, you won’t feel restricted as it is fitted with a new shoulder block that allows for full range of movement relieving unwanted tension in the chest, shoulders & bicep areas. 2014 autumn/winter updates New 70g WINDSTOPPER insulated shell fabric WINDSTOPPER 290 Soft Shell thermal inserts stretch panels aid fit during dynamic activity 80g POLARLOFT Duo insulation Mountain HC Hood is fully adjustable Alpine fit with pre-shaped & articulated sleeves Shoulder Shield construction Carry over features 2-way YKK moulded centre front zip with insulated rear baffle 2 zipped micro fleece lined hand warmer pockets Inner zipped security pocket Stretch cuffs & dual tether hem drawcords For all you kit geeks out there, the links below will take you to Mountain Equipments Information pages where they will explain this jackets different fabrics, fills & constructions techniques in greater detail.
