Peak Performance has launched a new waterproof jacket designed to move easily between wet-weather adventures and everyday life.
Part of the Swedish brand’s Autumn/Winter 2026 collection, the Treeline HIPE 2.5L Shell Jacket offers a less technical-looking alternative to the traditional mountain shell, pairing clean lines and a relaxed silhouette with year-round weather protection.
Hot on the heels of the Light Hike Collection, the new jacket uses Peak Performance’s proprietary HIPE 2.5-layer construction, providing a waterproof rating of 10,000mm and breathability of 10,000g/m²/24h.
Those figures make it best suited to commuting, walking, hiking and other everyday outdoor activities rather than prolonged exposure in extreme mountain conditions.
Speaking of harsher conditions, the Treeline HIPE 2.5L jacket is joined by the more protective Treeline GORE-TEX 3L Shell Jacket.
Priced at £350, it uses a tougher 70D ripstop outer, a three-layer GORE-TEX ePE membrane and a RECCO reflector.
It also raises the waterproof rating to 28,000mm, although its stated RET rating of under 20 puts its breathability in a more moderate bracket.
At 480g, it is the heavier and more substantial choice for sustained exposure to poor weather.
As for the Treeline HIPE 2.5L, the 50-denier ripstop face fabric should provide greater resistance to snagging and tearing than the thin material used by many lightweight waterproof jackets.
Weighing a mere 387g, the Treeline's 2.5-layer construction makes it convenient enough to carry when the forecast is uncertain.
Its relaxed cut leaves room underneath for additional layers, which also helps extend its usefulness beyond the warmer months.
Sweden’s everyday armour
Practical touches include large concealed hand pockets, adjustable cuffs and a drawcord hem.
The hood can be adjusted using one hand, allowing the fit to be tightened without stopping to put down a bag or remove a glove.
The understated branding and concealed storage contribute to a cleaner appearance than you would typically expect from a hiking shell.
This supports Peak Performance’s aim of creating a jacket that feels equally at home in an urban setting and outdoors.
“That relationship with the outdoors starts early,” says Sofia Gromark, VP Design & Creative at Peak Performance. “You grow up going outside with your family in all kinds of weather, so performance and comfort aren’t optional – they’re expected.”
The Treeline HIPE 2.5L Shell Jacket is now available at Peak Performance UK, Peak Performance US and Peak Performance EU in several colourways for men and women, priced at £220 / $250 / €250 (~AU$410).
