| Yeti Passion One Down Sleeping Bag |
 |
Passion bags are the fascination of the “Nothing“. They belong to the world’s lightest sleeping bags.
With their ankle-length zip fastener, lowest weight and pack size there is excellently plenty room left for sleeping. With a weight of 25g/sqm the Yeti Rip Stop nylon fabric is still extremely tearproof. Thanks to the calendered manufacture of the fabric, good wind- and water-proof characteristics are achieved as well. The high-quality filling is gained from extremely large Masurian (Poland) breeding geese.
This provides for an achievement of loft values of 900+ cuin at a maximum downs/feathers ratio of 97/3.
Comprehensive tests of the used fabrics offer the user a maximum of safety and comfort for skin-friendly fabrics and fillings

Our Verdict
Insanely light summer bag which uses the highest fill power down available, +900, the Passion One also packs down to an astonishingly small 18 x 12cm diameter. The quality of construction is excellent but the real performance is in the down, as it is the highest possible quality then (providing it is allowed to loft correctly) it will deliver the highest warmth to weight ratio.
Many ultralight bags save weight by reducing the length of the zip - the Passion One doesn't compromise and has a full length zip (no baffle) so that it can be vented and is easy to get in and out of.
Also some other bags in this category skip on the hood - which may not be required in the summer, with the Passion One the hood is included so that you can benefit from the all-encompassing warmth it provides.
This is our lightest sleeping bag by some way, it has a limited temperature range but is ideal for summer use, and you can push the boundaries by wearing clothing - checkout our down shirts and vests.
