PFC-Free DWR Treatment – All of namuk's technical materials are treated with a DWR coating (durable water repellency). It's not only water repellent, but also dirt resistant.

15K Waterproof / 10K Breathability – These membranes withstand water pressure equivalent to depth of 15 meters and don't let water penetrate even after hours of playing in the rain.

PrimaLoft® Bio™ – PrimaLoft® Bio™ is the first-ever synthetic insulation and fabric made from 100% recycled, biodegradable fibers. These fibers break down when exposed to the right environments, such as oceans or landfills. They are optimized to be more attractive to the naturally-occurring microbes found in these environments — returning the insulation and fabric to natural elements — such as gases.

PrimaLoft® Eco Insulation – The vegan insulation material PrimaLoft® Eco is light as a feather, water repellent, keeps kids warm — and is environmentally friendly, too! It's made of a mixture of recycled materials and PrimaLoft® virgin fibers, which combine to create a breathable, extremely efficient layer of thermal insulation.

Pre-Shaped Fit – namuk's anatomically pre-shaped products help maintain as much freedom of movement as possible, even when children have to be packed up nice and warm.

Adjustable Waistband – The waistband can be adjusted in height and width for the ideal fit for your child — whether you need to adjust for a growth spurt or just a hearty lunch.

Garbage Pocket – There's always something left over, whether it's the last bits of a snack or just a paper bag. namuk integrated a special garbage pocket for just these things. Once at home, the pocket can be turned inside out to empty it, then washed.

Climate Control System – A bit of quick ventilation if it happens to get a bit hot now and then? Not a problem! Namuk integrated a ventilation system into this product.

Overall Connection System – Nothing ends a day in the snow faster than getting snow in the pants. With the namuk "Overall Connection System," ski jackets and pants can be zipped together easily, protecting kids from invading snow even on the swiftest sled rides. Even different sizes and models from different seasons can be zipped together, easy-peasy.

Fully Taped Seams – This product features fully taped seams, providing optimal protection from water, because the seams are usually the first point where water penetrates the inner material. So kids stay dry, whether it rains or snows or there's just a little accident with a juice box.

YKK® Zippers – namuk only uses zippers made by market leader, YKK. That lets them guarantee the best quality and optimal performance. And it's easy-peasy to open the zipper, even in frosty temperatures.

Invisible Reinforced Bottom Hem – The bottom hems of the legs are reinforced invisibly with tear-proof Cordura material. That makes them robust yet comfortable to wear.

Reflective Details – It can be hard to see kids at dusk and in the dark. Different parts of namuk clothing and hardware reflect light, and therefore enhance safety. And of course, they look great too.
