Two new ultralight down jackets from La Sportiva might change how climbers and fast-moving travellers pack for cold days. The Lumina 100 and 200 were put through a solid real-world test this past November and December — multipitch routes at Red Rock Canyon in Nevada, long shady climbs in Zion National Park, and a trip out to Jordan's Wadi Rum — and the numbers alone are worth a look.
The headline stat is warmth-to-weight. A women's XS Lumina 100 weighs just 149 grams (5.3 ounces), stuffed with 70 grams of 1000-fill-power down, with fill making up roughly half the jacket's total weight — a ratio up there with the lightest jackets on the market. The Lumina 200, at 206 grams, carries 103 grams of the same down and proved the warmest jacket in the reviewer's sizeable collection, bar her heavyweight winter parka.
How you'd use them differs. The hoodless Lumina 100 works as a minimal belay-and-security layer for multipitch climbing: light enough to hang off a harness or wedge into the bungees of a chalk bag, and a like-for-like weight swap for an ultralight wind shell with far more warmth on offer. The hooded 200 is the colder-day option, worn over a fleece while climbing and thrown on at belays or around camp in the evening — including on chilly November missions up Shune's Buttress and Monkey Finger in Zion, where speed mattered with a shuttle to catch.
The trade-offs are the usual ultralight ones. These are stripped-back jackets: two zippered pockets, a full zip, no hang loop, no extras. The thin fabric feels fragile, feathers poke through more easily, and you wouldn't want to squeeze an offwidth in one. Still, two months of near-daily wear produced no real durability failures with basic care. The 200's hood deserves a mention — it fits snugly with no helmet, comfortably over one, without any cinch cords, which is genuinely rare. Sizing runs true, and the XS took a fleece underneath with room to spare; on cold camping nights the reviewer even layered both jackets together.
Ethically minded buyers get recycled Pertex Quantum fabric and Responsible Down Standard certified 1000-fill Italian down, plus a few patches of tenacious tape in the box to encourage repairs. Colours come in pairs: pink-and-navy (rosebay/night sky) or plain black on the 200. The Lumina 100 costs $289, the 200 $379.
Who should care? Climbers ticking off long routes in shoulder-season desert conditions, ski tourers wanting a midweight puffy, ice climbers, and anyone packing for alpine trips where every ounce counts. If you run cold at belays but hate carrying bulk, the Lumina 100 in particular solves a packing problem rather than just adding to the gear pile. Just treat the fabric gently — these are specialist tools, not everyday beaters.
