Haglöfs has described one of its latest jackets as being “rocket science”, with its incorporation of extremely light insulating material.

Designed as an alternative to a traditional bulky insulating layer, the L.I.M Barrier jacket is made with PrimaLoft Gold with Cross Core technology, a material in which micro denier fibres are fused with aerogel, a substance renowned for its insulating properties. Aerogel is used in space missions and is one of the lightest known solid substances.

The technology fits with the minimalist look of the range, said the company. The jacket also has a tough tear-resistant outer shell, DWR treatment for weather protection, and it is made with bluesign-approved and recycled materials.
