Only worn a couple of times because I prefer a pair of lined shorts. The Foundation short has been discontinued by TenThousand so if you love them and need a new pair, here's your chance. For general strength training, where you're having barbell friction and putting a ton of stretch into your gear, you need shorts built a little heavier. The Foundation Short excels well in this environment due to its outer shell. They not only resists abrasion but also maintain their integrity over time. Smoke and pet free home. No tears, abrasion, stains, or defects. Questions? Leave a comment below!
