Love these leggings and own a bunch of Woolley’s stuff. I’ve owned them for over a year now and wear them wherever from long haul flights to outdoor fitness in winter to ice skating and recently on trails and water activities in Patagonia both as is and under a pair of shell pants. They are hands down fantastic both in terms of material/craftsmanship, durability and design. High and soft waste band is super conformable, side pockets hold an iPhone and a thin wallet/bank cards and do not stretch. I love the side seams for an added definition/slimming effect. They hold up perfectly to wear - over a year, they didn’t stretch/sag a bit. Wore them recently on hiking trails in Patagonia famous for moody weather /strong winds and four seasons in a day; merino didn’t disappoint - keeps you warm when you’re cold and stays cool when you’re warm, even on a few super windy passes (and I’m talking polar wind gusts of up to 100km/hr) I didn’t need to wear windproof pants on top of them. Amazing! The version with pockets costs extra but they are super handy. Overall, excellent durable good looking product. Go Woolly!
