Between sizes
"This is my second one. My first one is a size medium and though the backside and legs fit well, since I have gained weight I find after riding for a while the waist band becomes too tight or uncomfortable. So I ordered the larger size. It is a bit too large and loose in the bottom but at least the waist band is bit more comfortable for my post menopausal tummy. I wish it had a bit more padding for the seat area but I do love the flexibility of wearing clothes over and them not looking like I am wearing diapers. Also, I have tried all of Terry’s undergarments and though I like a bit more padding especially for longer rides, my rubanesque thighs are uncomfortable with the leg bands. So, these are definitely the best for me. If they had a tad more padding, they would be perfect."
