Pure merino wool makes the Kepler Short Sleeve an ideal base layer for hiking a GR route on the continent, biking through Scotland or trail running on cool mornings.

• Breathable and temperature-regulating for all-day comfort
• Pure merino wool has a high warmth-to-weight ratio
• Naturally odour-resistant for wearing on multiple days

The 160gsm Kepler base layer performs over a vast range of conditions. Naturally breathable, wicking and fast drying, merino wool keeps you comfortable in both hot and cold weather, controlling your temperature throughout the day.

Weve used pure merino wool from non-mulesed sources and ultrafine fibres (17.2 microns). As well as being soft against the skin, these ultrafine fibres have an excellent warmth-to-weight ratio.

Merino wool is also naturally odour-resistant, so you can wear it day after day without stinking your mates out of the tent. For comfort under layers and rucksack straps, the Kepler has articulated sleeves with low-profile flat lock seams.
