Yeti Strato Ultralight Down Jacket

Yeti's Strato Ultralight Down Jacket leaves no stone unturned when it comes to quality of materials and construction using the highest quality ethically sourced down.

Yeti says:

Strato is the lightest fully functional men’s down jacket in the world. Weighing only 155 grams for a medium sized jacket, it is optimal for those who need a warm jacket but at the same time require ultra small pack size and the lowest weight possible. It is filled with premium Crystal Down 900+ in a 95/5 down mix offering high insulation at a minimum weight, making it ideal for those who at the same time need to keep both weight and pack size down to a minimum, but still want the comfort and security of a down jacket.

SERIES OF LIGHT-WEIGHT-PRODUCTS Since 1983, we have been developing high-quality down sleeping bags and down clothing. For adventurers and explorers we have always been fighting for each millimeter of pack size and each gram of total weight. However, in everyday live or on small trips the equipment of people often is still inappropriate.	THE TECHNOLOGY INSIDE The Next to Nothing Technology among others means that: for all Companyon products we are processing the currently lightest and most exclusive materials. Thus, the downproof rip-stop nylon fabric weighs just 25 grammes per square metre. The secret of lightness is based on the 1,000 kilometres yarn holding the downs together. This yarn has the size of a twentieth of a human hair, these 1,000 kilometres of yarn weigh only 140 grammes.   LIMITED EDITION In all over the world, there are just five weaving machines available who can manufacture such a fine material. All these machines can be found in the North of Japan. Each of them produces only 35 metres per day.   For this reason the delivery quantity of Companyon products is limited.
For this reason, we have created a professional equipment for everyday life with extremely small pack sizes under the label “Companyon“. The weight of Passion sleeping bags or ultra-light-weight clothing is hardly noticeable. Almost weightless they provide for a comfortable body climate and feel soft and silky.

Yeti's Strato Down jacket is billed as the lightest down jacket in the world, we don't think we can be certain if it is or not, but we can be certain of the sheer quality of Yeti Down products. The Strato has a down filled stand up collar and two zipped handwarmer pockets, it has a bound wrist and very lightly elasticated lower hem.

This type of garment is an ideal travel item where packed size and total weight are critical - you won't notice this in your luggage - and yet its there providing warmth when you need it. In the outdoors its a fantastic layering garment for use around camp. The down is 900+ Fill Power as measured by the EU method with yields a lower number than the same down tested using the US Method - ergo its better than 900+ when compared to most other manufacturers that quote the US figure. Every single detail of this range has been designed to be light yet perform.
