American brand Tani has just released a new collection of underwear called Shadow SP. The Shadow SP is described by the brand as the high performance cousin of their Shadow collection. Both are made from a light weight, soft fabric which is designed and patented in Italy. The special feature of this fabric is it’s compact knit which allows the edges to remain unfinished, meaning there is no need for stitching at the hem. The Shadow SP has an addition of a double layer bonded mesh which adds structure, support and shape retention.
