Great winter base layer
I have similar merino base layer from Isadore already few years which I am very satisfied with, so I was looking for another version. This one is also warm enough and even more elastic, so it was a good choice. Only I am worried about how long will last Isadore letters on cloth, because it seems not glued enough.Show full review -

Parfaite
Parfaite pour tous les sport d'hiver. Si vous êtes entre 2 tailles, la taille inférieure sera très collante mais pas trop courte, sauf si vous aimez que ça descende sur les fesses et le pubis.Show full review -
