Add Heat Heated Pants Liner

The heating is great and it is a really good system but the size are wrong. I previously bought the jacket which is great as well. I bought the size Large and since it was a bit loose, and the size chart matching my body suggest medium I did bought medium and it is too tight. I want to were some under lining on my between my skin and the heated pants and I can't with the medium. My normal pants size is waste 33" length 32". These fit my waste but are way too tight at the ties so I gave them to my girlfriend and bought one size larger... Apart from that they are perfect.
