The hood is giant sufficient that it will possibly maintain a pillow or you possibly can simply fold it backward and relaxation your head on it, utilizing the bag with out a hood, which is good in hotter climate.
Insulated with 750-fill energy down, the Ascent 30 has vertical baffles over the chest and horizontal baffles over the legs to stop down shift and make sure the down stays optimally distributed for heat. The insulation is structured in boxed baffles for max heat and to stop warm-air leaks from the needle holes that happen with stitched-through development.
The Ascent 30 has three zippers, two on the edges and one within the footbox. The precise zipper is half-length whereas the suitable zipper is full-length, so you possibly can open the bag huge in hotter climate or simply fold down the higher half, as illustrated above. The zipper and venting enhance the bag’s temperature vary fairly considerably: I’ve slept in it comfortably into the higher 70’s (F) by opening up the aspect zippers and utilizing it like a quilt, adjusting it throughout the night time as my physique cooled and temperatures dropped. It’s rather a lot like sleeping in your mattress at dwelling!

The hood is gigantic sufficient that you could put a pillow inside and nonetheless snag the hood round your head. It has an easy-to-grasp adjuster so you possibly can cinch the hood round your face. When it’s too heat to make use of, you possibly can fold the hood below the bag and use the Ascent as a hoodless sleeping bag, which is somewhat good. Sadly, you possibly can’t run the draft collar round your neck and snap it closed like a quilt because it’s not lengthy sufficient, though that may be a fantastic function. Maybe a future model can have that.
The down within the Ascent has been enhanced by the Extremely-Dry non-PFC water-repellent remedy. Whereas it doesn’t make the down utterly waterproof, it helps scale back the destructive results of dampness in order that it retains over 60% extra loft, absorbs 30% much less moisture, and dries out 60% sooner than untreated down (in line with the producer). Web web, the down in your bag will preserve you hotter in chilly and humid situations and dry sooner, which is especially advantageous on multi-day journeys. Nonetheless, the draw back of “waterproof” down is that the chemical waterproof coating does wash out when you wash the sleeping bag usually and renders the down much less waterproof than if it was untreated.
The Ascent 30 comes with a handy storage sack and a compression sack. The storage stack needs to be used at dwelling to increase the down’s lifetime and let it loft naturally between journeys. The compression sack shrinks the sleeping bag to five.5 liters, so it takes up a lot much less house inside your backpack. It’s fairly spectacular simply how small the Ascent 30 packs up when compressed, particularly when in comparison with a equally rated artificial insulated sleeping bag.
