## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    They are super warm and the internal material is super soft
  

*by R***E on Reviewed in the United States on January 19, 2018*

I wore these as an undergarment for my SCUBA Drysuit, way too warm for that and not exactly the thinnest option. However, I can't wait to use these snowboarding and ice climbing. They are super warm and the internal material is super soft.These are quilted and the patches on the knees add reinforcement to the area that will likely get the most abuse. The quality thus far is great, from the stitching to hold the quilted layers together. Time will tell how it holds up and I'll modify the review accordingly as I put these into use more.

### ⭐⭐⭐⭐ 







  
  
    Crotch area is a little too long / bieber pants
  

*by E***E on Reviewed in the United States on January 24, 2019*

These four layer pants are super warm!  I really like them, but they're not perfect.  The crotch area is too long and is shaped like Justin Bieber pants.  If it wasn't so squarish in the crotch area, they'd be perfect.

### ⭐⭐⭐⭐⭐ 







  
  
    Thick and warm
  

*by B***S on Reviewed in the United States on March 19, 2019*

They don’t have any tags showing care instructions or what materials they’re made of, but they’re warm, comfortable, and stretchy.
