One thing that never ceases to astonish us is the sheer number of

brands we've never heard of but are plainly producing excellent quality

kit and now there's another one, Yeti,

which specialises in down

sleeping bags and sleeping mats.

The background of the company is in the Far East where it's been around

for decades, but it was recently bought by Nordisk. The bags are now

handmade in Germany and fill power ratings are European.

The brand's now being imported into the UK by the people behind OMM

and Vasque

in this country - we had a sneak preview of some of their bags the

other week and were very impressed. In particular, we were bowled over

by the super lightweight, reddot design award-winning Passion One bag.

It's a beautifully-made bit of kit using 100 grammes of 900 fill-power,

hypoallergenic, harvested 97/3 Crystal

Down. The total filling of 125g

is housed in a shell made from super-lightweight Toray LightyGram

fabric - very light, silly name - and weighs a total of 265 grammes in

medium and 320g in large size. Pack size, as you can see, is tiny.

That's a standard cycling water bottle next to it.

The bag is comfort rated at +15˚C, has a Limit value of +12˚C and an

extreme rating of -1˚C, in other words, ideal for lightweight summer

racing and lightpacking. The bag is insanely light but still useably

warm. Unsuprisingly construction is minimalist with stitch-through

baffles and no zipper baffle, but it's very much a top-end, specialist

tool, built for a purpose. It's available now and retails for £280.

Still Light, But More Of

A Generalist...

Much more of an all-rounder is the VIB

250. It's still a lightweight bag, but far less

minimalist. Rated at -9˚C for extreme, +5˚C for limit and +9˚C for

comfort. It uses 800+ fill power, 95/5 fill power Crystal Down, some

250 grammes of it, and the total weight is given at 630 grammes.

A good option if you're tall too, with 175cm, 195cm and 205cm length

options. The baffles are computer filled to give an optimised

differential down distribution and maximise warmth and the zip has a

baffle.  Finally the bag has a waterproof base and toe to

increase resilience in condensation-prone tents. Again it looks like a

really good bit of kit, retail in the UK £230.

One For The Gurlz

Last but not least, the Sunrizer 600 Women has

a couple of neat, women's-specific features that are likely to cause a

bit of gender envy in many a cold tent. The bag has double-filled toe

and hip areas, an integral down pillow and, for ultimate luxury, a

luxurious, fleece-lined toe section - below.

The bag is cut smaller for women generally, uses 600g of 600+ fill

power Crystal Down and weighs in at 1145g. Comfort is +1˚C, Limit is

-5˚C and Extreme rating -21˚C. Looks like a comfy and ingenious

all-rounder with a price tag of £250.

Like Western Mountaineering, Yeti appears to be right up there in terms

of quality and definitely worth looking at if you're in the market for

a high-spec sleeping bag.
