Polartec High Loft Full-Zip Jacket
About Mountain Hardwear’s zip-ups: Mountain Hardwear's fleece zip-ups are serious technical mid-layers — Polartec High Loft and grid fabrics built for alpine use.
Is the price honest?
Premium at $160, set by the Polartec High Loft fabric and the alpine-grade build. Reviewers who want genuine warmth-to-weight and breathability for serious outdoor use consider it justified; casual buyers can spend less.
Our take
Mountain Hardwear's High Loft full-zip is a technical alpine fleece built around Polartec High Loft, a lofted fabric that traps a lot of warmth for its weight while staying breathable. It has zippered pockets, a low-bulk construction that layers under a shell and a trim, performance-first cut. Owners value the warmth-to-weight, the breathability during exertion and the durable build for serious outdoor use, with the trade-offs being a technical, climbing-oriented look and a price set by the Polartec fabric and the alpine engineering. It is a mountain mid-layer first and a casual fleece second.
