I said 'cool', but feel free to substitute with the appropriate terminology as I am very much not down with the lingo. 
DS is 11 and starting high school in September. He has ASD, so it's not a matter of just asking him about it as he is clueless. I remember very well what it was like to have the wrong bag, or trainers etc. I'm hoping it's not as bad these days, but I don't want to get the wrong things for him.
I'm not here for a lecture on how I shouldn't care. Life is hard enough for kids with SEN. He wants to fit in.
We need to get him a school bag and some black trainers for P.E. I'd also like to get him a smaller, every day bag that he can use to keep his phone and wallet in, plus any amount of sticks and random stones he seems to attract...
Any suggestions please?
