Passion One is the lightest option in the ultralight Passion range and the finest choice for an ultra light weight sleeping bag for any adventure where weight and pack size is an issue. The stich through construction keeps the weight down and make sure the down filling is kept in place. The filling is the finest European goose down on the market and the very soft and down proof fabric makes the Passion One extremely soft and comfortable.
A selection of the finest and most voluminous European down. Down is by nature perfectly insulating and highly packable. Sourced according to the Yeti Ethical Down Code and RDS to ensure animal welfare.
Next to Nothing
Highly breathable, light and down proof fabric. The secret behind; an ultra-fine thread and dense weaving. No coating or down bags, allowing the down to breathe freely. And it feels next to nothing.
The most simple design for a sleeping bag is to use the stitched through construction. Using this method the shell and lining are stitched together directly on top of each other to create the chambers into which the filling is inserted.
