The Ridge Merino Cloudripper Fleece is built for backcountry skiers, resort riders, and cold-weather hikers who desire the full-zip convenience of a traditional midlayer jacket enhanced with the high-performance attributes of merino wool. It is well suited for active days on snow where fluctuating body temperatures require frequent venting adjustments without shedding layers entirely. Classified as a midweight midlayer, the Cloudripper utilizes a balanced blend of merino wool, polyester, and spandex. The natural wool fibers provide reliable thermal regulation across shifting temperatures and resist the buildup of unpleasant body odors, while the synthetic polyester fibers deliver structural strength and accelerate dry times. The interior brushed finish feels remarkably soft against exposed skin or over a lightweight base layer, while the spandex content ensures full range of motion for poling and scrambling. On the downside, the Cloudripper is noticeably heavier and takes longer to dry than 100% synthetic grid fleeces once it is completely saturated with moisture. While the wool blend provides excellent everyday durability for trail and snow use, it still requires more thoughtful laundering care than pure polyester fleece to maintain its elasticity and prevent fabric degradation over time. **Highlights** - Merino wool, polyester, and spandex blend balances warmth, stretch, and durability - Natural antimicrobial properties resist odor buildup across multi-day wear - Full-zip front allows precise, quick temperature dumping on steep ascents - Soft brushed interior provides excellent comfort directly against base layers - Secure zippered pockets accommodate mountain accessories and warm chilled hands **Watch-outs** - Retains moisture longer than purely synthetic active fleece when saturated - Bulkier in a pack than minimalist ultralight half-zip midlayers - Needs gentle washing cycles to avoid degrading the natural wool fibers

The Ridge Merino Cloudripper Fleece occupies a distinct middle ground in cold-weather layering systems. Designed around a hybrid knit containing merino wool, polyester, and spandex, it blends the natural thermal regulation and odor resistance of animal fiber with the structural tenacity and faster drying capability of synthetics. Independent testing recognition, including accolades from Treeline Review as a top full-zip midlayer, highlights its practicality for active cold-weather pursuits where steady output collides with frigid ambient temperatures. Unlike traditional 100 percent synthetic fleece garments that often build up body odor during back-to-back mountain days, the Cloudripper relies on its wool component to remain wearable over extended trips without laundering. The full front zip provides critical mechanical venting for backcountry ski tours and brisk winter ascents, allowing users to dump excess core heat quickly without breaking stride to shed outer layers. While the piece sacrifices some of the pure packability and rapid evaporation seen in ultralight technical grid fleece, it delivers substantial everyday utility. It serves demanding winter users who prioritize next-to-skin comfort, quiet movement, and reliable warmth over shaved ounces.
Target User and Applications
The Cloudripper is engineered primarily for cold-weather hikers, ski tourers, resort riders, and snowshoers who face broad swings in metabolic heat output. Because climbing sustained alpine grades generates immense body heat while ridge tops and descents rapidly draw it away, layers requiring total removal become a liability. The garment targets outdoors people who prioritize the immediate temperature control offered by a full-length zipper over the minor weight savings of an ultralight pullover. It suits travelers and multi-day backcountry enthusiasts particularly well because its wool content suppresses odor far better than petroleum-based alternatives, reducing the need to carry spare midlayers on multi-day itineraries.
Materials and Fabric Construction
Ridge builds the Cloudripper using a three-part textile blend combining merino wool, polyester, and elastane. The merino content acts as the thermal buffer, maintaining warmth even when damp while breathing efficiently during moderate exertion. Polyester reinforces the knit, imparting tensile strength that prevents premature abrasion wear and expediting moisture transfer away from underlying base layers. The elastane content provides structural stretch across the shoulders and arms, ensuring the garment moves fluidly under a hardshell. Inside, the fabric features a softly brushed texture that enhances loft, traps a micro-climate of dead air for insulation, and feels non-irritating over bare arms or light short-sleeve tops.
Thermal and Moisture Performance
In real-world mountain environments, the Cloudripper functions as a reliable thermal engine in sub-freezing to cool conditions. The midweight loft provides sufficient insulation under an uninsulated shell on freezing ski lift rides, yet breathes adequately to prevent immediate overheating during sustained climbs. However, moisture management reveals a classic material trade-off. While the polyester content helps move sweat outward, merino wool naturally holds a percentage of moisture within its fibers. If a user works at maximum output and completely saturates the fleece, drying times will run visibly slower than those of a pure polyester grid fleece like a Patagonia R1 or Mountain Hardwear AirMesh.
Durability and Fabric Maintenance
Combining synthetic filament with spun wool gives the Cloudripper far greater tear strength and shape retention than a pure merino garment of equivalent weight. Pack harness straps and hip belts cause less immediate surface pilling than they would on pure wool tops. Still, the material demands more cautious maintenance than bulletproof synthetic pile. Laundering requires cold water, gentle detergents free from fabric softeners, and air drying to preserve elasticity and avoid damaging natural fibers. High heat in a home dryer will accelerate fiber breakdown and cause shrinkage, meaning users must commit to basic garment care protocols to ensure multiple seasons of service.
Fit and Layering Mechanics
Designed as an active midlayer, the Cloudripper is cut with a standard athletic profile that sits close to the torso without constricting movement. This trimmed silhouette prevents excess bulk from bunching underneath a dedicated shell jacket, while the spandex content allows reach and overhead extension when planting ski poles or scrambling over rocky passages. The hem and cuffs are cut to seal out drafts without creating pressure points under gloves or harnesses. Sizing tracks true to standard outdoor dimensions, leaving sufficient volume to layer over a lightweight base layer while remaining slim enough to slip smoothly under a compact down puffy.
Market Context and Alternatives
In the broader midlayer market, the Cloudripper occupies a niche between high-end pure wool offerings from brands like Smartwool or Icebreaker and ubiquitous synthetic grid fleeces. Compared to top-tier synthetic pieces, the Cloudripper offers vastly superior multi-day odor performance and a softer, less plastic-like hand feel, but at the cost of higher overall packed volume and heavier weight. Against premium, fully wool-knit jackets that frequently retail at substantial price premiums, Ridge provides a much more budget-accessible hybrid option that also gains improved physical durability from its synthetic reinforcements, making it a compelling value proposition for functional winter utility.
How we picked
We started with a long list of insulated vests and midlayers that people actually buy, cut anything that could not clear our baseline for durability and field performance, then ranked the 10 that were left against the same criteria.
