Customer Rating: 5 out of 5 stars (Excellent)
Reviewer Name: Brian V. (Verified Purchase)
Review Date: 2025-12-02
Customer Feedback:
C-Theory low rise briefs check all the boxes:\n1. Front pouch doesn’t pull back and is large enough to hold my oversized junk.\n2. Low rise, contrasting waistband and stretchy fabric are all very flattering. These look as good on me as they do on the C IN 2 model. \n3. Comfortable all day.\n4. Liked my initial purchase of 2 so much that I bought 4 more.\n\nJust which these came in grey!

Reviewer Name: Marcus K. (Verified Purchase)
Review Date: 2025-03-09
Customer Feedback:
One of the last items of clothing that looks a bit more eye-catching and special. The rest of the collection is unfortunately all very monochrome and not very interesting. Similar to the "scrimmage" and "throw back" collection.
