Buying guidance

Microchill vs. Summit Grid: which fleece should you buy?

Microchill is the value pick: a soft, breathable grid fleece for everyday warmth under a shell. Summit Grid and Polartec High Loft options cost more but offer higher warmth-to-weight for serious shoulder-season trips. If you're asking which Mountain Hardwear fleece is the warmest, step up within the range; if you want the cheapest reliable layer, Microchill wins. Washing is simple: machine wash cold with technical detergent and skip fabric softener to preserve loft. All Microchill purchases ship free over $45.00 and are returnable within 30 days of delivery.

What's the difference between Microchill and Summit Grid fleece?
