Description
The Ultralight StormLoft™ Down Underquilt will lighten your pack and improve your sleep with its ultralight design and materials! Our goal was to source the lightest weight fabrics (10D ripstop nylon) and insulation (800+FP down) and then craft them into an ultralight designed underquilt.
The ultralight StormLoft™ underquilt will enable you to shed pounds out of your pack helping you go farther, faster and with less fatigue. The long vertical baffles and contoured cuts keep the down locked into place and reduces the weight even further!
The fully integrated suspension system allows you to quickly adjust the quilts height and tightness with one adjustment point. You can then seal out any drafts with the draft baffle and bungee adjustment!
Live Ultralight by going farther and sleeping better with the StormLoft™ Ultralight underquilt!

The storm loft insulation is our most up to date insulation offered, the difference is that it is RDS Sourced (responsibly sourced), is 3rd party verified/guaranteed to have 800+Fill power or better, and has been treated to be water resistant to the down level, so not only is the shell water resistant, but so is the down inside of the bag. The standard insulation is still a good option however it does not have the same certifications as the new storm loft and has not been treated to the down level for water resistance. If it gets damp, the water-resistant down will be able to maintain loft easier compared to the untreated down. Please keep in mind that this down is not water-proof or comparable to synthetic insulation. If it gets soaked, the down will not loft properly or insulate until dry.
- 5 USES IN 1: utilize this bag as an UNDERQUILT, a POD SYSTEM, a TECHNICAL BLANKET, a SLEEPING BAG or buy two and make it into a DOUBLE SLEEPING BAG!
- CUT WEIGHT & SAVE SPACE with ultralight highest quality 800 fill power down which makes this bag weigh in at 2.1 lbs and compress to 11 x 7 inches! Down is natures (and the world's) best insulator. Nothing beats high quality down's weight-to-warmth ratios so you'll never regret buying this bag!
