The no-snag zipper design enhances the luggage capability to take care of constant heat all through the evening. The cosy mummy design successfully traps warmth near your physique, maximizing insulation.
And, we like Western Mountaineering’s conservative temperature ranking for the UltraLite. Whereas most producers overstate their consolation stage claims, the UltraLite 20 is a welcome exception. It’s completely filled with down fill – boasting 16 ounces, or a full pound, of feathers – so we’ve discovered it could go fairly a bit decrease than the advisable 20°F consolation stage. To check this, we slept via frigid October and November nights within the Arizona and Utah deserts, the place temps hovered round 10°F. Paired with base layers and a heat sleeping pad, our analysts stayed toasty heat all evening lengthy.
The one downsides with regards to heat? The Ultralites’ giant baffles. Its down tends to settle pretty rapidly in these greater areas after a couple of dozen occasions unpacking and repacking the bag. Fortunately, the feathers are simple to redistribute with guide massaging to eradicate chilly spots, however it could develop into a little bit of a activity to arrange for colder nights. And, the sacrifice you’ll make for such distinctive heat is the match is slender via – which is typical for a mummy bag, because it eliminates lifeless areas that may get chilly – though the cosy match limits what number of layers you possibly can put on.
