I have size 7/8 in black + anthracite heather. The fabric is thin like a t-shirt (thin like sportswear) and they are breathable. They can be used as pajamas or to play with on a hot summer day. If I hold the shorting board up to the light I can see through it. They feel solid. The seams are reinforced and I haven't noticed any thread loss or overlapping seams. The material doesn't bother me, but the laces on the shorts aren't long enough. They are functional but can therefore be tightened in the belt. It happened instantly, and it's almost like missing a shoelace because they can't be tied. In addition, they are suitable for everyday use or before going to bed. They can be washed in cold water and tumble dried on a low setting. Suggestion for improvement: lengthen the belt.
