The Indyeva Selimut RDS Vest keeps us warm and comfortable as we get our steps in around the local park or get an early start on tackling a 14,000-foot peak. The lightweight RDS-certified down regulates our temperature perfectly, allowing excess warmth to escape as we work up a sweat and trapping heat close to our body when it's exceptionally chilly. The vest is treated with both a DWR coating and a layer of thin wax to protect us and the down within from wind and light rain.
