I've had a pair of jodphurs from there, reasonable price and ok quality, not much of a choice in the one local to me so can't comment on anything else, they did seem to have a good range of hats though.
Yep - great for bits and pieces. Good fleeces, socks, jackets. Not sure on the quality of their safety equipment though i.e. hats as would prefer to buy a recognised make. Only one head etc.
I only go to the one near Calais as nothing near me in the UK, so know they have a good selection there.
Some of the stuff is very good. I still own and wear the first ever pair of jodhpurs I owned (now 3 years old) which I got from Decathlon.
I bought Jock a fluorescent exercise sheet for £12.99. It's made of the same mesh seen on sports tabards so doesn't interfere with his body temperature at all, which means I can use it all year round. The only annoying thing is that the reflective horse pattern is on the wrong side as it's made in France (although I use it as an indicator to check I'm on the right side of the road - I get confused with that sort of thing easily).
I've also got some other clothes from their Fouganza range which are all holding up fabulously.
The only thing that does suit it's price is the Mane and Tail Conditioner I bought (Fouganza), you need to use a lot of that stuff for it to be effective!
