Never worn perfect condition rain-resistant trench coat: Substantial weight: not as heavy as a winter coat but definitely not thin or flimsy. Warmth factor will depend on your tolerance, but I would wear this down to about 30-40 degrees. Upper body portion of lining includes a lightweight quilted layer. Double breasted Raglan sleeves Removable hood Very deep front pockets Belt button in back to hold belt in place See photo of London Fog coat sizing NOTE- IMO this is a generous medium with plenty of room for layers underneath Knee Length: Back length collar seam to hem 42” Underarm seam to hem: 31.5”
