I walk 2 hours every morning and I have been using this primarily for that. Have been pleasantly surprised at how breathable it is considering its thicker material. The price is reasonable and the quality solid. It has become my go to walking outfit and I've even worn it a couple of times just to lounge around the house.
Comfort: Flexible and breathable are probably the first 2 words that come to mind within comfort. This tracksuit can easily be used as pajamas or just a casual lounge outfit for around the house.
Drawstrings: Most drawstrings on sweat pants/track suits feel flimsy with some plastic like film holding the ends together. The drawstrings here are thick, with a silver end piece that feels sturdy. Kind of an odd thing to call out but it stood out to me based on my experience with other drawstrings.
