Outdoor Vitals StormLoft UnderQuilt 2022 - 2020 Review by The Good Ride

This is the 15 Degree StormLoft Down UnderQuilt from Outdoor Vitals. This UnderQuilt is super lightweight and is a great fit with their StormLoft Down TopQuilt. It gives you a great insulated system to keep you warm while hammock camping.

How This Review Happened: We borrowed this from the company for an extended demo and returned it.

Ethics Statement: We don’t get paid by the manufacturer to write these reviews.  We do make money from the “Where To Buy” links. But this is our best attempt at an honest and objective review from an average camper’s perspective.

Testers: Steph

Weight: The UnderQuilt I was using was the 15 Degree Long weighing 1 lb 10 oz.

Here are the other weights and temp ratings that they have available.

0 Regular: 1 lb 12.5 oz
15 Regular: 1 lb 7.5 oz (23.5 oz)
30 Regular: 1 lb 4 oz (20 oz)

0 Long: 2 lb
15 Long: 1 lb 10 oz
30 Long: 1 lb 6 oz (22 oz)

Dimensions:  76″ long x 44″ wide


Although I didn’t get a stuff sack to stuff the Outdoor Vitals StormLoft UnderQuilt into, it could pack down to be pretty compact. I think the ratio of the insulation to the weight and pack-ability were really well done. The UnderQuilt from Outdoor Vitals keeps it simple so they aren’t using any extra materials that you don’t need. This way it stays lightweight and the extra materials stay minimal. The stuff sack size that comes with this UnderQuilt is: 12″x 7″.


For being an ultralight option, I felt like the 10D ripstop nylon is durable enough that I wouldn’t be worried about damaging it all the time. The ripstop nylon seemed strong enough so you don’t have to stress about it being damaged easily. But if anything were to malfunction, Outdoor Vitals has a lifetime warranty on all their products.


This UnderQuilt from Outdoor Vitals was very easy to use. You just clip the ends to your hammock suspension rope on both ends and its pretty much set up. I like that it has the pull bungees on each end so you can customize the amount of draft you want under your hammock. You also have the bungee running along the sides of the UnderQuilt so you can cinch it up higher to really enclose the hammock, or let it hang a little lower.

This was my first experience with using an UnderQuilt with a hammock system. I usually just freeze a little every night in my hammock when I go camping in it. It was a strange experience to be laying in the hammock and feel warm air on my back. It is a game changer for hammock sleeping in cooler environments for sure.

The 30 Degree TopQuilt mixed with their 15 Degree UnderQuilt was super comfortable for me. The temperature only got down to 40 degrees when I slept in it, but I didn’t feel like I had to layer up or anything. And usually I do. The insulation temp. is rated for men. Normally women’s sleeping bags have a little extra insulation, so the 15 degree rating on the UnderQuilt might be a slightly higher temp rating for women.


If you are looking for a hammock insulation option that is lightweight, and has a great weight to warmth ration, the Outdoor Vitals UnderQuilt has a good variety of different temp ratings and sizes available. It comes at a good price point for the amount of insulation you are getting. And it is a really simple sleep system matched with their TopQuilt should keep you warm and comfortable all night.

If this review helped, we’d appreciate if you:
