Bombproof alpine protection in the Helixir 3L Shell Pant for hard charging days
What Our Gearhead® Experts Are Saying:
"I’ve worn the Helixir 3L Shell Pant M on rugged alpine days where durability really matters. The Spectra-reinforced fabric feels insanely tough without killing mobility, and the venting does a great job when the pace picks up. The gaiter and hem design work well with boots and crampons, which makes these pants feel truly mission-ready."
We trust the Helixir 3L Shell Pant from La Sportiva when terrain turns sharp and conditions get serious. Built for exposed alpine routes and long days above treeline, these pants give us the confidence to move efficiently through snow, rock, and mixed conditions without worrying about our outer layer.
A rugged 3-layer waterproof construction blocks wind and moisture while standing up to abrasion from skis, crampons, and rocky terrain. Spectra fiber reinforcement adds exceptional strength, while articulated knees and stretch panels keep movement smooth and unrestricted. Side ventilation helps regulate temperature, and boot-compatible hems with water-resistant flaps seal out snow when conditions deteriorate.

Frequently Asked Questions
How should I size the La Sportiva Helixir 3L Shell Pant for alpine layers?
The Helixir has a slim, close fit and no insulation, so choose the size based on La Sportiva’s men’s size chart and your waist, seat, and inseam measurements. If you plan to wear substantial insulation or ski-touring layers underneath, sizing up can provide more room.When are the La Sportiva Helixir 3L Shell Pants most useful?
They’re built for ski mountaineering, backcountry touring, and exposed alpine climbing in wet, snowy, windy, or abrasive conditions. The three-layer shell and Spectra® reinforcement suit demanding terrain; for warmth, pair them with suitable base or insulating layers.How does the Helixir compare with lighter hiking or softshell pants?
The Helixir prioritizes weather protection and abrasion resistance over the lighter feel and everyday versatility of many hiking or softshell pants. Its slim, structured shell design is better suited to technical alpine use than running or casual hiking.How do I set up the La Sportiva Helixir pants over ski or mountaineering boots?
Open the ankle zippers to pull the pants over your boots, then adjust the hems and position the internal gaiters. The gaiters are designed to accommodate crampons, while articulated knees and stretch panels support movement on steep terrain.How should I care for the La Sportiva Helixir 3L Shell Pant?
Follow the sewn-in care label, wash with technical-shell detergent, and avoid fabric softener and bleach. When water no longer beads on the face fabric, restore the DWR with a treatment suitable for three-layer shells; clean and dry the pants before storing them loosely.
