Due to Apex supply issues the JMT is the only synthetic insulated product we can offer during the pandemic.
The JMT Sweater is our lightest insulated shell named after the classic John Muir Trail in the Sierra.
Built with Climashield APEX, a lightweight yet remarkably efficient synthetic insulator, the JMT will retain some warmth when damp, and will dry and recover more quickly than down.
This is a simple jacket, lean on features, with the focus on as much warmth for the weight as possible. In its basic configuration the APEX insulation makes up over 55% of the total weight.
The JMT is available with a full separating front zipper or a half length pullover style zipper.
We build it with or without an integrated hood. The hood option is fully insulated and offers complete coverage to above the chin - but it is not helmet compatible. For most users, only a very thin beanie will fit under this trim hood.
Key design points to take note of:
* The JMT with the full zipper is without any exterior pockets.
* The hood casing have a fixed, pre-tensioned shockcord.
* The JMT does not have an elasticized waist cord.
* The sleeve ends are cut trim with no additional closure offered.
APEX by Climashield, a superior continuous filament synthetic insulation, is the choice here.
We have 2 weights available. For summer season mountain use in the continental US (and the Alps) the 2.5 oz/yd level is appropriate. Shoulder season users can select the 3.6 Apex level for the torso.
The APEX specs:
2.5 oz/yd Climashield APEX - 85 g/m - light, compact, 2 season
3.6 oz/yd Climashield APEX - 122 g/m - more weight/bulk, 3 season
The JMT can be configured with a 10d shell in a number of different colors. It's an ultralight fabric for folks who want the lightest, but realize that abrasion and tear resistance is minimal.
The stock cut is aimed at providing a short jacket with a trim fit, best when used over only one or two lightweight thermal layers. Compared to the PCT line of APEX hoodies, the JMT Sweater is a size smaller in the torso while the sleeves are the same.
The chart and configuration menu below outlines the many options for sizing the JMT Sweater. Tall people may wish to go up in zipper and back length. Likewise, folks with long arms will know when to add to the sleeves.
