Mountain Equipment Mens Trembler Fleece Jacket

Slim Fit. When in doubt, choose a larger size

All about this product



The Men’s Trembler Jacket is a lightweight and highly breathable hybrid jacket for the biggest Alpine rock routes and most exposed mountain running. Made with Exolite 45, a stretchy double weave soft shell fabric, the Trembler Jacket offers durability with a smooth finish.

With a windproof, quick drying, yet super-breathable micro-grid lined body and lightweight Lumiko stretch fleece arms, this close fitting hybrid jacket is the perfect layer for athletic and high output mountain activity. Flatlocked seams improve next-to-skin comfort and help prevent rubbing and chafing when wearing a backpack. There are two zipped hand pockets, and one Napoleon chest pocket to keep your mobile phone and other valuables secure. Low bulk cuffs allow room for adding layers or gloves and the double-layer collar and elastane-bound hem help to keep the warmth in and provides flexibility. The jacket packs into its own hand pocket with twin karabiner carry loops to attach it onto your backpack. Whether racking up vertical training kilometres or putting it all to the test on a non-stop range traverse, the Trembler is essential kit.
