NORTHFACE SUMMIT CASAVAL HYBRID HOODIE - TNF BLACK-NPF

This jacket is a high‑performance mid‑layer from the Summit Series, designed for active mountain use or demanding outdoor conditions. It features synthetic insulation and technical shell fabrics, delivering warmth, breathability and mobility. The “NPF” designation signals a non‑PFAS durable water‑repellent finish for an eco‑conscious finish. The black colour (TNF Black) keeps the look sleek and versatile for both trail and everyday use.

Materials & Construction

• The body fabric is a 40‑denier plain weave (≈91 g/m²), made of ~88% nylon and ~12% elastane with a non‑PFC DWR finish for water‑resistance. 

• Under‑arm and hem panels use a stretch‑woven double weave (≈187 g/m²) composed of recycled polyester and elastane, also with non‑PFC DWR and FlashDry™ processing. 

• Insulation: Uses the VENTRIX™ synthetic stretch insulation — ~60 g in the body, ~40 g in the hood; the construction includes laser‑perforated zones in the back panel for dynamic venting when active. 

• Design features to support movement: No shoulder seams (reducing bulk under backpacks), raglan sleeves, stretch under‑arm gussets and hybrid paneling (insulated body + stretch side/hem zones) giving a balance of warmth and mobility. 

• Hood: Attached, helmet‑compatible with a pre‑tensioned elastic opening and rear cord lock for fit‑adjustment. Center front zipper is exposed, reverse‑coil, water‑resistant. 

• Hem adjustment: Internal drawcord hem with single‑point adjustment to customise fit and trap warmth.

Fit & Style Details

• Fit: Regular/standard fit; designed to allow layering beneath if needed but still streamlined. 

• Colour: TNF Black with non‑PFAS DWR (NPF) — gives a clean black look while emphasising eco‑friendly treatment.

• Back length: For women’s version approx. 24.75″ (≈ 63 cm) from size XS. 

• Use Case: Ideal for active pursuits such as hiking, mountaineering approaches, ski touring or any high‐output outdoor activity where you may switch between movement and rest phases and need adaptive insulation.

Benefits

• Excellent warmth‑to‑weight: The synthetic VENTRIX™ insulation traps heat when at rest, and the perforations open when you’re moving hard to release excess heat, offering a dynamic thermoregulation. A

• Mobility‑focused: Hybrid construction with stretch zones ensures the jacket doesn’t restrict movement when climbing, scrambling or layering under a shell.

• Weather‑resistant: The shell fabric and DWR finish offer resistance to light moisture and wind, making it useful in changing weather conditions.

• Packable and layering‑ready: Because it’s designed as a mid‑layer with active insulation, it can be used alone or under a shell depending on conditions.

• Eco‑conscious: Recycled materials and non‑PFAS DWR strengthen sustainability credentials.

Considerations

• While water resistant, it is not a fully waterproof outer shell — for heavy prolonged rain you’ll still want a dedicated shell on top.

• The hybrid design, with insulation in the body plus stretch panels, means side/under‑arm zones are less insulated — if you stop for long periods in cold wind you may feel cooler in those zones.

• For casual urban wear it’s more technical than typical fashion jackets; the fit and styling reflect outdoor performance rather than lounge wear.

• The black finish, while versatile, may attract lint or dust more visibly than lighter colours — occasional care may help with upkeep.
