Product Description

The Greylock 3 torso length under quilt is designed with current state-of-the-art features and is intended for the hammock user who is seeking an ultralight approach to bottom insulation. It is a dual differentially designed quilt and has body contouring radial baffles. In use the Greylock under quilt is effortless to attach and it will maintain its loft under any conditions. The Greylock 3 under quilt comes equipped with full length, channeled shock cord suspension that allows the user to make minor adjustments to their under quilt position. For those desiring to use the traditional JRB corner under quilt suspension the Greylock also comes equipped with corner mounting tabs. When filled with 800 fill power down this torso length under quilt weighs just 17 ounces. It comes complete with a JRB compression sack.

Note: Torso length under quilt users typically use their sit pad or back pack as foot and lower leg insulation.

Tip for best results:

Activ-dri down™ – Activ-dri™ is a hydrophobic down treatment that keeps the down drier, while having no adverse effects on loft, fill power, or warmth retention. Activ-dri down is still down insulation and should be protected from direct exposure to moisture. All types of insulation, whether down or synthetic, will degrade in insulation capability if wetted.

    Wow, I can’t believe how good this quilt is. Decently priced, takes up almost no room and weighs next to nothing. These guys know what they are doing.

    I used my Graylock 3 this weekend for the first time in the mountains of northwestern VA. Low temperature on Friday night was in the mid-high 20′s with 15 mph winds most of the night. At first, I was hesitant about not having a full-length under-quilt, but my 20 degree bag (with fleece liner) was perfect. I stayed warm all night. Great product, great customer service, and I highly recommend it!!!

    Love this under quilt. Got it last spring for a trip to pictured rocks in the u.p. Got down into the low 30s one night with high winds and heavy rain. Was warm all night. Woke to find my tarp was dripping on the side of the quilt, but the water just beaded up and ran right off. Quilt was perfectly dry. This is not the last jacks r better product I will buy. Want a full length for colder weather. If your not looking to save weight I would go that route.

    Just got back from a Sierra snow shoe trip. Took the Greylock down to 21 degrees. Accuweather said 12 degrees “real feel”. Impressive how the torso length is sufficient to keep warm. I had a 2x2ft section of reflectex under my feet and stayed comfortable. Granted each time I reached forward to knock snow off the tarp, I let a little cold air in, but it didn’t take long for the heat build up again and get comfortable. Gotta make sure you keep the under quilt suspension over your outside shoulder and feet!

    I have the Greylock 3 and the seirra sniveler. And love them. We went camp at hogs camp gap back in February 2015 it was 7 degrees over night and they work pretty well for being rated at 20 ish. Needless to say they make a great product.

    Bought one this year, use it on my Hennessey hammock and it works great. Wasn’t sure I was going to like the torso length but it does the job. Coldest I’ve been in yet was 34 degress and I was warm all night. I also have a JRB top quilt. I’m an ultralight backpacker so weight is always important.

    I have been using this quilt (900FP) all season in the South East of the USA. From Florida to North Carolina and in sub freezing weather. I am an ultralighter with a base weight of 8.5lbs with a Shenandoah to match. I LOVE THESE quilts.
