What's Changed? The key updates are in the construction. L.O.F.T 3D baffling has been rolled out across more of the range, helping to reduce cold spots and keep the down evenly distributed. Combined with TILT lining technology, this improves thermal efficiency without adding bulk. Fabric choices have also been refined, balancing durability and packability where it matters most. It results in a clear, logical lineup. The Mythic focuses on ultralight performance, the Neutrino offers all-round versatility, the Alpine leans towards durability and protection, and the Ascent prioritises comfort and space.
