Mountain Warehouse at Junction One in Antrim are having a sale and today there's an additional 20% off everything including sale items. Think the sale's been on for a few days and finishes today, might want to check to be sure before driving out.
I'm not sure what their gear is like but I picked up what seems like a decent small adult jacket (for a boy) for £30 or so and stuff like showerproof jackets, fleeces, outdoor trousers and waterproof trousers were all very cheap. Would definitely be a good time to get the kids outfitted if you know they need stuff with the summer around the corner.
Edit:
Seems there's a sale on the website too.
