Headtorch maestros Petzl have joined forces with French outdoor brand Picture to make a small collection dubbed 'Adventure in a New Light'. Think sustainable fabrics and plenty of purple and you're on the right footpath. Which brings us nicely to this t-shirt. That mid-weight organic cotton is prime for year-round wear, there's a nice and subtle bit of embroidered detail on the hem, and that 'Predator vision' mountain-scape woven chest label is particularly good.
