Trail Winder - Modular Add On
Specs
| Temp rating | -20°F |
|---|
Description
Please read before purchasing.
This listing is for the modular insulation layer only. A complete Trail Winder Underquilt is not included.
If you are adding this to an existing Trail Winder that does not already have the required snaps installed, you will need to ship your underquilt back so the snaps can be added and the fit verified.
An appropriately sized stuff sack is included and will be sized to accommodate both your original Trail Winder and the Modular Add-On. If you choose to add a compression sack, it too will be based on the overall bulk of your set up.
Features
- Designed specifically for the Trail Winder Underquilt
- Adds a second layer of Climashield® Apex insulation
- Installs between the hammock and the existing underquilt
- Fully enclosed shell protects the insulation from dirt and debris
- Uses a snap attachment system for secure installation
- Stuff sack included
How the Modular System Works
One of the challenges with underquilts is that a single quilt rarely performs comfortably across a wide range of temperatures without compromises.
The Trail Winder Modular System addresses this by allowing a second insulated layer to be added to the existing quilt while maintaining the same lay orientation.
The modular layer installs between the hammock and the original underquilt. This positioning minimizes gaps between the insulation layers while allowing the sides of the primary underquilt to continue blocking wind from reaching the additional insulation.
Estimated Temperature Increase
Because this system combines two separate insulation layers rather than using a single, thicker layer, temperature improvements should be considered estimates rather than absolute ratings.
| Added Insulation | Estimated Temperature Increase |
| 2.5 oz Apex | 15-20°F |
| 3.6 oz Apex | 25-30°F |
| 5.0 oz Apex | 35-40°F |
| 6.0 oz Apex | 45-50°F |
Notes
If you have a custom-sized Trail Winder, please contact me before purchasing so that compatibility can be verified.
Temperature improvements are estimates only and will vary depending on factors such as your existing underquilt configuration, shelter setup, wind, humidity, and individual comfort preferences.
