Every 1000 m up, the air loses 6.5 °C. Ten technical garments, each rated for a band of it. Climb the mountain to see what you wear.

for seasons.

−6.5°

Every 1000 m you climb, the air loses 6.5 °C. In one mountain day you cross more climates than a year in most cities.

7 bands

We cut the thermometer into seven bands of 6.5° each: exactly 1000 m of climbing per band, from Glare to Void.

10 garments

Each one is named after the temperatures it was built for and dyed the colour of the middle of that range.

What altitude are you running at?

Tell us how high, we read the air up there and dress you for it. Or skip the maths and give us the temperature.

LAPSE vs normal clothes

Same day.
Half the weight.

Pick a day. We dress it twice: once with LAPSE, once with what is usually in the drawer (cotton, a hoodie, a rain jacket).

+22° at 800 m, up to 4,000 m in 20 km/h wind → you need −4° to +22° covered.

When it gets wetCotton holds water and stops insulating; our knits and merino blend keep working damp and dry in about an hour.

LayersEvery LAPSE piece has a job (base, mid, shell, legs), so you add or drop one layer instead of changing outfits.

Normal-clothes weights and ranges are our estimates for typical retail pieces. LAPSE is a concept brand: weights and ratings are design targets.
