# Janji Rainrunner Pack Jacket 2.0

**Verdict:** A light, truly waterproof running shell with built-in venting that reviewers liked for cold rain; it can still get warm and clammy on hard efforts, and it runs small.

- **Best for:** Cold, wet runs where you need real waterproofing without the bulk of a hiking rain jacket.
- **Not for:** Dry cold, where a wind shell breathes better, or runners who insist on pit zips.
- **Downsides:** Can feel hot and clammy when working hard, per Treeline; Runs small; Janji advises sizing up; No waist drawcord, per Outside

## What reviewers say

- Best all-around cold-weather running jacket: stretchy fabric, good ventilation, cuffs that keep hands covered and a longer back; the tester stayed comfortable through 40s°F downpours with gusty wind, and the only complaint was the lack of a waist drawcord.

- Tested but not awarded in the men's guide: noted the 20k/20k rating, taped seams, strong DWR beading, PFAS-free build and new 360-degree venting as a clear step up from version 1, but found it hot and clammy when sweating and wanted pit zips.
