Weighing a mere 9.5 ounces, the Atom SL Hoody delivers exceptional warmth-to-weight performance. The updated 2025 model features CoreLoft Compact insulation strategically placed where you need it most.

Stretch side panels enhance mobility on tough trails, while the DWR finish sheds light precipitation. When not wearing it, this marvel compresses down to the size of a softball in your pack.

Storm clouds on the horizon? The Rab Downpour Light has your back. Made from Pertex Shield 2.5-layer fabric, this rain shell offers complete waterproofing without the typical clammy feeling of older rain jackets.

Articulated sleeves prevent the dreaded hem rise when reaching for handholds. The adjustable hood with a laminated peak keeps your vision clear during downpours, and pit zips provide quick ventilation during steep climbs.

Mountain ridges often bring unexpected gusts that cut through ordinary layers. The Shadow Wind Hoodie excels in these conditions with its ultralight 20D ripstop nylon construction.

What makes the 2025 version special is its improved breathability while maintaining near-complete wind resistance. The elastic cuffs and adjustable hem create a microclimate around your core when temperatures drop.

At just 5 ounces, there’s no excuse to leave this protective layer behind.

Black Diamond Distance Wind Shell

Minimalists rejoice! The Black Diamond Distance Wind Shell might be the ultimate emergency layer. The entire jacket stuffs into its own chest pocket, creating a package smaller than your water bottle.

The NanoSphere treatment repels moisture while maintaining breathability during high-output activities. Reflective piping adds visibility during dawn and dusk hikes.

The 2025 model introduces a more durable YKK zipper and reinforced shoulder areas where pack straps typically cause wear.

Mountain Hardwear Ghost Whisperer Hoody

The legendary Ghost Whisperer returns for 2025 with responsibly sourced 800-fill RDS-certified down. This iconic piece retains body heat even when temperatures plummet unexpectedly.

A standout feature is the new hydrophobic treatment that maintains insulating properties even in damp conditions. The quilted construction prevents down migration, eliminating cold spots that plague inferior jackets.

Despite offering serious warmth, it weighs just 8.8 ounces and compresses to the size of a large apple.

Patagonia Houdini Air Jacket

Named after the famous escape artist, the Houdini Air helps you escape both wind and overheating. The magic lies in its double-weave fabric that blocks 90% of wind while allowing excess heat to escape.

The 2025 version introduces recycled nylon with a more textured inner surface that feels less clammy against skin during exertion. A slim fit layers perfectly under a shell when conditions deteriorate.

The entire jacket disappears into its own chest pocket, weighing a feathery 4.1 ounces.

Feathered Friends Eos Down Jacket

Hand-crafted in Seattle, the Feathered Friends Eos represents the premium end of ultralight insulation. The 2025 model features 900+ fill power goose down—the highest loft commercially available.

The Pertex Quantum shell material creates an incredibly light yet surprisingly durable exterior. Elastic cuffs and an insulated collar trap warmth exactly where you need it most during frosty mornings at camp.

Unlike mass-produced alternatives, each jacket undergoes individual inspection before shipping.

Outdoor Vitals Ventus Hybrid Active Jacket

Why choose between warmth and breathability? The Ventus Hybrid places 800-fill down in core areas while using stretchy fleece panels under the arms and sides where you sweat most.

The innovative 2025 design introduces antimicrobial treatment in high-sweat zones, reducing odor during multi-day treks. Zippered hand pockets double as ventilation when partially opened.

This clever design adapts to your body’s changing needs throughout the day, from chilly mornings to active afternoons.

Enlightened Equipment Torrid APEX Jacket

Custom-made for each order, the Torrid APEX offers synthetic insulation that performs remarkably well when wet. Unlike most jackets, you can specify your exact measurements, baffle size, and fabric colors.

The 2025 version introduces a more durable 10D ripstop nylon outer shell that weighs practically nothing. The Climashield APEX synthetic fill maintains loft even after compression, a common failure point in lesser synthetic jackets.

At 7.5 ounces, it delivers exceptional warmth-to-weight performance.

Mac in a Sac Origin 2.0 Emergency Shell

Sometimes the best jacket is the one you actually have with you. The Mac in a Sac Origin 2.0 creates the ultimate no-excuses emergency shell, weighing just 3.5 ounces and packing down to the size of your fist.

The 2025 update features improved waterproofing with a 5,000mm hydrostatic head rating. Fully taped seams prevent leakage at critical junctions.

While not designed for extended downpours, it provides essential protection when caught in unexpected weather far from shelter.
