Thick legging/jeggings for work

[WooYa]

Does anyone know where I can get thick leggings or black jeggings for work? I spend a lot of time running around so I need them to be durable but not see through!
Thanks

M&S Heatech leggings are good and the H&M heavy leggings. Both not see through.

I buy jeggings for dog walking, so I don't want expensive ones, and the Tesco and Asda ones are good, and I also have from Marks, all under £15. Think stretchy material, but in least bit see through.

I buy H&M £8.99 jeggings for dog walking, chilling at home etc. They are comfy, durable (so far for me anyway) come in a variety of colours and are a bargain! They also have a proper zip and button fastening and real back pockets which some jeggings are lacking :)

I love these:
