Ideal for hot summer days in the mountains, the 150 COOL MTN MISSION TS W from Ortovox is a technical t-shirt for women that offers all the comfort you need in the mountains. Featuring BETA-SPUN technology, a protective polyamide sheath, the fabric is more resistant to abrasion and tearing. At the same time, the fine Merino fibres offer unique comfort and ensure optimum temperature and moisture regulation, while the Tencelâ"¢ fibres have a cooling effect thanks to their smooth surface and high evaporation capacity. Finally, the loose, relaxed fit of this model means it's comfortable to wear while you're in action.
