An economy underquilt (UQ) that is Chinese made and Chinese QC'd.


  • Price
  • Water-resistant
  • Easy to set up


  • Not rated accurately
  • Construction/Fabrication is sloppy
  • Poor customer service

This is not a terrible place to start if you are beginning to hammock camp. The Hammock Gear UQ is of much greater quality for the same price, and I wish I had bought that first. OV is great at advertising and marketing, but they really should put that into the product.

  • The StormLoft 15 Down UnderQuilt is lightweight.
  • The cost is incredibly low for such a warm product.
  • It packs down to the size of a football.


  • The suspensions system can be tricky to set up efficiently for the first few tries.
  • The length of this under quilt felt shorter than marketed.

Hammock Camping isn't for the faint-of-heart. While tents are generally simple to pitch, hammocks involve a tremendous growth-curve. However, Outdoor Vitals' StormLoft 15 Down UnderQuilt makes moderating your sleeping temperature easy. Paired with a Hennessy Hammock, this setup is nearly unstoppable. 


  • DWR Treated
  • Hybrid Baffle Design
  • Outdoor Vitals has a Lifetime Warranty
  • 800+ Fill Power Down
  • Contoured



  • As a DWR coated product, the StormLoft is water resistant.
  • After a few months of use, this quilt shows no signs of wear. I'm confident in its construction and durability.
  • You can make adjustments to this underquilt while you're inside of your hammock, which isn't always the case. 
  • This underquilt is more likely to make you sweat than shiver. 

How does the StormLoft compare to other products?

  • Competitive Products range from $200-329, and 12.5 oz to 2.5lbs, making the StormLoft quite competitive in terms of both cost and weight.
  • Hyke and Bykes' Antero 15 Degree UnderQuilt costs $329 and weighs 2.49lbs.
  • WarBonnets' 20 Degree Yeti Underquilt costs $200 and weighs a stunning 12.5oz. 
  • Outdoor Vitals' StormLoft 15 Degree UnderQuilt costs $214 and weighs 1.47lbs. 

Final Thoughts:

If you're not interested in getting seriously into backpacking or camping, there are simpler sleep systems. But if you're not intimidated by the hammock learning curve, the StormLoft under quilt does a terrific job of helping you retain warmth. Outdoor Vitals does a terrific job of providing quality products. Overall, Outdoor Vitals' 15 degree StormLoft performed impressively well in the backcountry. 


I spent a few months testing this under quilt in Colorado's backcountry on various backpacking trips. Temperatures ranged from the low 30s to the mid 40s. I typically sleep really cold, and this quilt never disappointed me in terms of warmth. Conditions were dry. While this is my first under quilt, I'm an experienced hammocker.
