I've worn my shirt about 4 times in the past month, each time it has felt like an emotional boost and has made breastfeeding easier on planes, at parks, at the shops, and around family who become uncomfortable with my toddler frequently feeding. A couple of times I've felt comfortable I've forgotten to zip back up. I do find my hands are sometimes so full that I need to hold the shirt in my mouth to pull the zipper down with one hand, this happens with other hidden zipper feeding tops too so it's probably more reflective of my excessive multitasking. As with most synthetic fabrics I found it difficult to wear in heat and especially humidity, when it's cooler to cold I'm very comfortable in my shirt.
