Update 1/12/26 - Currently all sources of Apex 6.0 Climashield are out of stock and on back order.  So, until more 6.0 Apex becomes available, I will be combining a layer of 2.5 oz and 3.6 oz to achieve the same temperature rating.

The Trail Winder UQ uses the design of a standalone UQP as a starting point and then adds a layer of Apex Climashield synthetic insulation to make it an effective Underquilt.  I am currently trying to keep all weights in stock, but from time to time based on demand, the 7.5 and 10.0 may need to be ordered.

It is available in either Asym orientation or a symmetrical orientation.

Asym orientation is based on which way you lay in the hammock and the insulation is cut on the angle to save weight and pack space.  The Broad Width option adds 6" to the shoulder width for those with wider shoulders.

For those who do not have a dedicated lay, such as those who toss or turn during the night, changing their orientation, a full width cut provides more uniform coverage.   This will increase the weight and bulk obviously, especially as you get into the heavier weight insulations such as 7.5 or 10 oz.  

Combine the Trail Winder with an Eclipse Top Quilt for a total warmth solution

Eclipse Top Quilt

Modular System - As we all know, it is hard to get one quilt for a wide range of temperatures, without some serious tweaking or compromises in comfort.  With the design of the Trail Winder, adding a 2nd layer of insulation (in the same orientation as the base layer) is now a possibility. 

The additional layer is fully enclosed in a shell fabric to keep the insulation clean and debris free.  It utilizes a set of snaps that lines up with a set of snaps on the quilt itself.  (Please note that a standard Trail Winder without the modular set up, will not come with the corresponding snaps on the quilt.  There is an option in the drop down menu to add the snaps only to the quilt, so that if you want to future proof the quilt, you will not have to send it back in to get the add on)

Features:

• Made from using Dutch's Ion fabric or the Argon (49, 67 or 90) line of materials (custom fabrics are possible as well)
• Layer of Apex Climashield insulation sewn in at your preferred lay orientation
  
• Length - From 8' to 11' lengths are available (The best lengths are 1 - 2' shorter than you hammock length. For example, for an 11' hammock, either the 9 or 10' versions work best).
  
• Width of Base UQP Portion - 55-57" (depends on starting width of fabric)
• Suspension included - Adjustable shock cord loops at each end with Mini Biners.  
• Enough shock cord is included for use on a variety of length hammocks or quilt stacking situations.
• 5' section on each side is shock corded.  Easily adjust how snug it is to your UQ or hammock
• Includes stuff sack sized for UQ (and modular add on, if purchased)
• Weights will vary depending on options chosen (see charts below) **
• For reference, the shiny side would be facing up (next to the hammock), while the duller side with the DWR treatment would be towards the ground
• The last picture in the gallery shows the approximate dimensions of the insulation.

Additional Options:

• For storing, a separate stuff sack can be purchased for the modular piece only
  
• Optional Compression Sack available (long term storage in a compression sack is not advisable.  Letting your UQ air as much as possible will extend its longevity).  Please note that quilts with an overall temp rating of 12 oz or higher will not fit in the compression sacks I stock
  
• Optional oversized stuff sack made from NoSeeUm netting allows quilt to loft and breathe while in storage

Temperature ratings* on insulation weights:

2.5 oz -    50^o F
3.6 oz -    40^o F
5.0 oz -    30^o F
6.0 oz -    20^o F
7.5 oz -    10^o F
10.0 oz -  -5^o F

*Please note that temperature ratings are from the manufacturer of Apex Climashield.  They are considered comfort ratings and from customer feedback, that has held true in most cases, but not all.  There are many factors that can affect ones' comfort level including whether one sleeps cold or hot, wind chill, humidity among other factors.  Additionally, since an underquilt only provides coverage to one side of the body, pairing it with a top quilt, blanket, or some other form of covering insulation, will maximize its full warming potential.

Estimated Weights:

Note that the following charts are based on the 9' length.  Each additional foot of material adds .5 oz for Argon 90 and .6 oz for Ion.  (e.g. If you choose the 11' version in Ion, add 1.2 oz to the below charts for estimated weights). Argon 67 saves approximately 2 oz and Argon 49 @ 3.25 oz.

** Displayed Weights are estimates based on the advertised weights of the materials used.  Actual weights may vary slightly.
