Think of the TREWth 3L Primo Bibs as the seasoned mountain veteran that's seen every storm and somehow keeps getting better with age. Born 16 years ago and refined through countless powder days, these bibs are the Swiss Army knife of mountain protection – sustainable, intelligently designed, and ready to laugh in the face of whatever gnarly conditions you'll throw at them. Whether you're hunting fresh lines or battling sideways snow, this is the one pant you'll want between you and the elements.
Primo Fabric – Sustainably built with less impact, but still packed with the waterproofing, breathability, and durability that you want and need for long days in the mountains. The woven face fabric takes 100% recycled nylon (GRS certified) and constructs it into an ultra-durable oxford weave with a slight mechanical stretch. The final product is Trew's most durable, comfortable, and sustainable outerwear.
