Keela Alpine Advance shell pants
The Alpine Advance has a sturdy build quality, using Keela's 'System Dual Protection' which as well as being waterproof and breathable also provide a natural thermal barrier, making them surprisingly warm for what is effectively a shell. Keela also claim this system is far more effective in terms of breathability than other systems.
Features are fairly minimal - two-way full-length leg zippers with stormflaps and Velcro closures, Velcro tab waist adjusters, reinforced knees, inner ankles and seat, one small rear zipped pocket, inner non-slip rubber snow gaiters and Velcro tab adjusters at the ankle. They also have attachments for braces although these must be bought separately.
So if you like your pants to have lots of pockets and vibrant colours they won't appeal; but if you want a good value, utilitarian pair of pants for pretty much any winter activity you're in business.
