Endeavor 3L Shelter 2027 – Shell Jacket

The Endeavor 3L Shelter is a technical shell jacket built for riders who push long days in serious mountain conditions. Without any insulation layer, it pairs with your own mid-layers and delivers uncompromised weather protection for all-season, high-output riding.

At its core, a three-layer construction pairs a 20,000mm waterproof membrane with a fluorine-free Bio DWR finish made from up to 90% bio-based materials — so the face fabric sheds rain without affecting breathability, drape, or feel. Every seam, including the hood, is fully sealed, and Aquaguard waterproof zippers run throughout. Underarm vents let you regulate temperature on the climb, while the helmet-compatible hood with a soft peak and a longer rear hem round out the technical fit. Storage is well-considered: a Napoleon chest pocket, a season pass sleeve pocket, and two large hand pockets keep your essentials accessible without bulk.

Who it's for

The 3L Shelter is made for the rider who knows exactly what conditions they're heading into and wants gear that won't hold them back. If you run warm, ride hard, and layer strategically, this jacket handles the weather while you handle the mountain. It's also a strong choice for backcountry touring days where breathability and packability matter as much as protection.

FAQ

• Is this jacket insulated? No — the 3L Shelter is an uninsulated shell designed to be layered over your own mid-layers, giving you full control over your warmth system.
• What makes Bio DWR different from standard DWR? Bio DWR uses a fluorine-free formula sourced from up to 90% renewable, bio-based raw materials. It repels water and stains without the environmental impact of traditional fluorinated coatings, and it doesn't change how the fabric feels or breathes.
