We’ve designed the Ortega shirt to feel just as soft, light and comfortable as cotton, with the added performance of synthetic fabrics. It’s the sort of shirt that you’d wear to stay cool on a hot trek or bike ride but happily wear out for dinner afterwards.
- The comfortable natural feel of cotton and a fabric that stretches with you
- Super wicking and fast-drying to keep you cool, plus UPF 50+ protection
- Polygeine® anti-odour treatment and can be washed and dried overnight
In baking heat, a looser fitting cotton shirt can feel more comfortable than a close-fitting base layer. But there’s nothing worse than walking in a sticky, sweat-sodden cotton shirt all day so we’ve designed the Ortega to combine the benefits of both.
The light fabric has a soft, natural feel that moves with you and the tailoring around the shoulders provides additional freedom. This stops the shirt from feeling restrictive under a rucksack and allows you to stretch forwards on the bike or for gaining extra trekking pole leverage.
Because the fabric’s synthetic fibres don’t absorb water, the Ortega is naturally wicking and extremely fast drying. But, on top of that, the yarns in the fabric have been given a permanent wicking treatment. This speeds up evaporation to keep you cool and dry, even under a beating sun.
We’ve intentionally chosen lighter colours to reflect as much heat as possible and the fabric has a UPF of 50+, providing a high level of sun protection, whether that’s abroad, at altitude or during the height of British summer.
Polygeine®anti-odour technology keeps you (or at least your shirt!) smelling fresher for longer on cycle tours and and multi-day hillwalking trips. Plus, because the Ortega is so fast drying, it can be easily washed and dried overnight in a hostel sink/closest body of non-mucky water for longer stretches of travelling.
"By choosing a fabric with inherent mechanical stretch and tailoring the shirts for movement, we’ve eliminated the need for spandex (which holds moisture), keeping the shirt as light and fast-drying as possible." - Ronnie, Design Manager
