There wouldn’t be anything wrong with either of those jackets
I regularly pick through my local Sports Direct looking for bits of kit on the cheap – I was in there on Saturday and grabbed a new ‘nalgene’ style water bottle, various base layers and a couple of small dry bags, all of which I confidently expect to function just as well as anything I could buy from more expensive brands.
In that context, I had a quick look at the lightweight down jackets and made the decision to walk on by – the fabric is okay, but the down is very poor quality and you can feel the clumps in the jacket. I’d rather spend the £30 or so on a synthetic jacket from somewhere like Decathlon than a down jacket with poor quality filling.
