The Montbell Rain Trekker Jacket is a feature-filled jacket that earned high marks from our testers for its combination of waterproofness and breathability. Montbell built this jacket using a single piece of fabric. This unique K-Mono Cut design reduces both weight and the number of seams for better protection from the elements. Any seams are fully sealed to prevent moisture entry.

The Rain Trekker from Montbell is an incredibly light-weight 6.9 ounce jacket designed to provide warmth, wind protection, and light rain resistance.

The Rain Trekker is a 2 layer jacket, built from Gore-tex Infinium Windstopper. This is a very light weight material that is composed of a thin outer fabric layer, and a breathable and water resistant inner layer that have been laminated together. The jacket has two zippered hand pockets, an adjustable hood, Velcro adjustable cuffs, and an elastic adjustable waist. Designed to be as light as possible, it also uses the impressive Komo Cut technique, which makes almost the entire jacket, aside from the hood, out of a single uninterrupted piece of fabric. The goal is to reduce seams, which reduces weight, improves reliability, and also eliminates many places that water could otherwise seep in. The jacket is available in four colors, a Male and Female variation, includes a stuff sack, and retails for $179.

Most shells at this low of a price come with compromises on breathability and packability. And most shells at this scant weight are low on features but high in price. The Rain Trekker dodges all those pitfalls, making it ideal for milder winter climates. When a cross-country skiing outing in Washington’s Methow Valley turned rainy, “I was sure I’d get clammy, but I never felt like I was wearing this jacket in the rainforest,” one tester says.

The Rain Trekker also squashes down to the size of a bratwurst.
