Review: Perfect for Mountain Biking and Cycling - I have been using the C-In2 Core Long Underwear as the base layer under my bib tights for riding in the most brutal New England winter in decades. The C-In2 Core Long Underwear are thin, warm and comfortable. Nothing to improve upon. Im 6' 205 pounds and the XL fit me perfectly. I have also been using the C-In2 Core Long Underwear for routine winter activities such as snow removal and hiking with the dog. They are all I need under a pair of jeans.
Review: A bit low rise - Good fit, good material, but a bit low rise, and the crotch is a bit bulky due to the 'pocket'. Hence I will be returning.

### ⭐⭐⭐ A bit low rise

Good fit, good material, but a bit low rise, and the crotch is a bit bulky due to the 'pocket'. Hence I will be returning.

### ⭐⭐⭐⭐ Some Good, Some Disappointing
*by D***A on October 17, 2021*

I wear a 34”waist/34” inseam and since there is no Tall size available I ordered the XL, hoping they would be long enough without being too big in the waist. And the risk paid off. They are long enough and the waist is fine. In fact I think they might be too snug on anyone with a larger than 38” waist size. The fabric is not bulky and they fit easily under a pair of jeans. The disappointment is with the pouch. While they are better than flat front undies, the pouch is nowhere near as accommodating, supportive, or comfortable as what you get with brands like Obviously or Krakatoa. Unfortunately they don’t offer long underwear. Overall I’m pleased with the purchase.
