Two jackets, three different weather situations – triclimate jackets are based on the original mountain layering system and, as such, are really versatile. The Inlux Triclimate Jacket is comprised of an outer and inner jacket. The outer jacket is a two-layer DryVent shell that’s waterproof, windproof and breathable. Worn alone it’s your protection from wind and rain on active days in milder weather. The inner jacket is lightweight and synthetically insulated. When this one is worn alone it provides warmth on cool, dry days. Wear them together and you have full-on protection from wet, windy and cold conditions.
