drohan These very comfy and warm. Wash well. Recommend 👍 These very comfy and warm. Wash well. Recommend 👍

null Bobbles after one week of wear Product bobbles Not recommended though it does keep body warm

gss09 When new they were great, but gradually shrunk At the start these were fine but wash after wash the legs got shorter, after a year they now barely reach my short socks so I would not buy again, And yes, 30 deg wash and dried overnight on hanger in front of AGA

PaulyH70 Extra insulation These are good quality long johns. Nice material, strong elastic that keep them up unlike with cheaper versions

Lesal Good value Nice soft material bought as Christmas present so hoping they are a good fit

SMM59 Husband Loves Them Bought a pair of these last winter for my husband and he loved them, so purchased a second pair this winter. Last years were 37% wool, this years 50% cotton (and no wool), but he's very happy with them and they seem to be just as warm. They wash well.

Ontrendygranny Cosy Good fit and cosy. Useful colour, to wear instead of cold jeans in the winter
