Present for 11 year old boy.

H and M are very popular amongst my 12 year old DS and his friends, as is River Island. They’re not as nice as Joules in my opinion but they’re very popular amongst that age group here.

Abercrombie and Fitch perhaps ? Nice tops and hoodies.
My teenage GD wears Hollister but she is in adult clothes.

My 11 year old grandsons have become very particular about brands. Current favourite is Rascal and I got some bits online for them reduced for Black Friday. Not cheap but the quality is good and has street cred IYKWIM.

Hollister, Jack Wills or Superdry are all “trendy” with teens. Our GS’s would appreciate a hoodie/sweatshirt from these.

My nephews 11 and 7 respectively wear a lot of Next clothes.

Superdry is apparently out now Grannygravy so my teens tell me but the other two are still on track as is JDsports
Calvin Kliens and anything Adidas or Nike

I've purchased a gift vouchers for a Climbing Venue, where they have huge walls and rock ooutcrops the youngsters can climb, with safety harness of course.

My grandson loves this.

There may be many other leisure places which an 11 year old would like and which sell gift cards for single or multiple sessions.

PS: I posted this only as an alternative to clothing because my daughter-in-law doesn't believe in "labels" which make some poorer children feel left out and have others boasting about their designer gear.

Debenhams perhaps.

John Lewis usually has very good teen and pre-teen gear. My two youngest grandsons (12 and 14) have a lot of clothes from there.

I like the climbing idea.

So do I as I always avoid buying clothes once they're past six or seven years old. They prefer to choose their own so I don't want to risk them never being worn.

My 12 year old DGS likes both the the long and short-sleeved "T shirts" from Sainsbury's. Usually sold as two or three in a set. And pyjamas from M&S (the short-sleeve ones.)

Now custom patchwork clothing is being used for gifts. sewmisfits.com/ has more like this. i would love to say that you should go for it.

As this was asked Dec2nd I m guessing this has already been solved
