About the ThermoBall Trekker Jacket
The North Face's ThermoBall synthetic insulation — 11.5 g/ft2, made with 100% recycled polyester polyfill and engineered to replicate down's warmth while still performing wet — in a lightweight 15D nylon shell with a non-PFC DWR finish that stows into its own left hand pocket.
Down-level warmth that still works wet
Three colorways at $240.48, sized S–3XL — the second-highest price point in the collection after the Castle Valley Triclimate, reflecting genuine technical insulation rather than just a warm-looking jacket.
