MERINO DENIM is softer and warmer than regular denim. Featuring a slim fitted leg and a mid-rise waist height that sits on the hips. Woven from 20% Merino Wool, 79% Cotton and 1% Elastane. This garment is machine washable. If you're unsure of your size we suggest you go down in size, not up in size as the fabric includes 1% elastane which will give a little.
