I've written about the Under Armour gear before - it's great quality, true to fit, breathes well, and is durable. Most of our players wear the brand, and for good reason. The pants are very flexible without being weak. The belt loops are strong, zipper and snaps are strong and sturdy as well. We use UA for pants and also for underlayers. The synthetic fabrics seem to breathe more easily than others, which is great when you've got multiple layers on. We do use the Marucci slider shorts underneath - but nearly everything else is UA. Can't go wrong. We do end up replacing a pair of the three in the rotation every year, and the ones with holes get relegated to practice duty. Overall they're very durable and VERY comfortable.
