So. Much. All our outerwear is made with a 4-way stretch that moves in any and every direction for ultimate comfort. This also means if you prefer a firmer/tighter fit, you can easily size down to get a 'slim fit'. All lining is also made with stretch fabrics, and our waist bands boast two side panels made with a durable heat-activated elastic. This means they will stretch and mold to your body shape as they warm up from your body heat.
