Quick answer
Focus on three things: a waterproof rating that matches your expected rain intensity, a fit that allows layering without being baggy, and features like venting and hood design that match how you'll use the jacket.
Waterproof rating: what the numbers mean
Rain jackets often list a waterproof rating in millimeters (e.g., 5K, 10K, 20K). This number refers to how much water pressure the fabric can handle before leaking. For light showers and everyday city use, a 5K rating is usually enough. For heavy downpours or extended time in the rain, look for 10K or higher. The Global Jacket has a 10K rating, making it a solid choice for most rainy conditions without being overbuilt for occasional use.
Fit: athletic vs. relaxed
A rain jacket's fit affects both comfort and performance. An athletic cut is trimmer and works well for active use like hiking or biking, but it may not leave room for thick layers underneath. A relaxed fit, like the one on the HighPeak Jacket, gives you more freedom of movement and space for a mid-layer, making it a better choice for variable weather or casual wear. Try your jacket on with the layers you plan to wear underneath to check for restriction.
Key features to consider
Look beyond the shell. A structured hood that stays put in wind, venting pockets or pit zips to release heat, and a packable design all add real value. The Global Jacket includes venting pockets and a structured hood, plus it's lightweight and packable for travel. The Topo Designs x Colorado Rapids HighPeak Jacket offers a stretch fabric that adapts to movement, which is helpful if you're active in changing conditions.
Decision rules for choosing a rain jacket
- Match waterproof rating to your rain exposure: If you face only occasional light showers, a 5K jacket is sufficient. For frequent or heavy rain, choose 10K or higher. The Global Jacket's 10K rating covers most needs without overkill. Check the rating before buying; don't assume all rain jackets are equally waterproof.
- Choose fit based on activity and layering: Athletic fit for active use with minimal layers. Relaxed fit (like the HighPeak Jacket) for casual wear or when you need room for a fleece or sweater underneath.
- Prioritize venting if you run warm: Pit zips or venting pockets let you dump heat without taking the jacket off. The Global Jacket's venting pockets are a practical feature for active use or warmer rain. Without venting, you may overheat quickly during exertion.
