Newbie here!
I've been searching everywhere for an upgrade to my Mountain Warehouse Backpacker 2 tent so I've done a fair amount of internet research that might help answer this question.
My old MW Backpacker 2 weighs 1.9kg and has withstood some pretty foul weather over the years - it's never leaked or collapsed. Having trawled through the internet, I'm beginning to think now that there is probably only a couple of hundred grams to be saved (I don't hike with trekking poles) and only if I spend upwards of £400. Only now am I realising how great my Mountain Warehouse tent is!
Unfortunately, it looks like my old MW Backpacker 2 isn't for sale any longer, but there is a new dome-shaped model on their website:

If it's anywhere near as good as the previous wedge-shaped model, then I would highly recommend it! Especially as it's only £64.99 delivered. Hope that helps!
