Down sleeping luggage aren’t cheap, so when you can solely afford to purchase one sleeping bag or quilt, you need one that’s going to carry out throughout the widest temperature vary. That’s the worth proposition that the Sea-to-Summit Ascent 30 delivers on with a ventable foot field and twin facet zippers that allow you to fold down the highest of the sleeping bag like a blanket.
The Ascent 30 has a relaxed mummy form that strikes a very good stability between thermal effectivity and area to maneuver round it, making this a very good bag for facet sleepers like myself. The hood is massive sufficient that it might maintain a pillow or you may 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 building.
The Ascent 30 has three zippers, two on the perimeters and one within the footbox. The appropriate zipper is half-length whereas the left zipper is full-length, so you may open the bag vast in hotter climate or simply fold down the higher half, as illustrated above. The zipper and venting improve the bag’s temperature vary fairly considerably: I’ve slept in it comfortably into the higher 70’s (F) by opening up the facet 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 residence!
Each of the facet zippers have an anti-snag head and do a very good job of stopping snags on the shell material. There’s a snap on the high of every zipper, on the perimeters of the hood, so you may stick your arms out the perimeters and “put on the bag like a hooded jacket” if you’d like, which is nice when you like to sit down as much as make espresso in your tent within the morning with out getting chilled. The footbox additionally has a zippered opening for venting when you’re too heat at night time, though its zipper doesn’t have the anti-snag head or really want one as a result of it’s so brief.
The hood is gigantic sufficient that you may put a pillow inside and nonetheless snag the hood round your head. It has an easy-to-grasp adjuster so you may cinch the hood round your face. When it’s too heat to make use of, you may fold the hood underneath the bag and use the Ascent as a hoodless sleeping bag, which is relatively good. Sadly, you may’t run the draft collar round your neck and snap it closed like a quilt because it’s not lengthy sufficient, though that might be an excellent characteristic. Maybe a future model may have that.
The down within the Ascent has been enhanced by the Extremely-Dry non-PFC water-repellent therapy. Whereas it doesn’t make the down fully waterproof, it helps cut back the adverse results of dampness in order that it retains over 60% extra loft, absorbs 30% much less moisture, and dries out 60% quicker than untreated down (in response to the producer). Web web, the down in your bag will maintain you hotter in chilly and humid situations and dry quicker, 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 water resistant 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 residence 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 area 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.
