Why we chose The North Face Summit Series L3 50/50: Lightweight, breathable, warm
Price: £470 / 520€
We first caught a glimpse of 50/50 technology, The North Face’s new and rather unconventional way of designing down jackets, when we spotted the Summit Series L3 50/50 Down Jacket at ISPO 2020. It sat at the heart of TNF’s Advanced Mountain Kit; a capsule series that represents the highest level of athlete-driven textile development.

The North Face Summit Series L3 50/50 combines lofty 800 fill power down with an air-permeable face fabric and a unique baffle construction to make for a highly technical ski mountaineering mid layer for alpine climates, or a belay / summit overlayer for the warmer spring season.
The North Face Summit Series L3 50/50 Construction
The unique baffle construction is the most interesting talking point of this jacket. It features a series of baffles that, when combined with the air permeable face fabric, help to dump heat. Rather than a conventional baffle construction, where the baffles are stitched together in series, 50/50 down features a gap between each baffle. This gap allows air, and moisture, to flow through freely when you’re working up a sweat in the mountains.
