Rab Infinity Microlight Jacket Review


Rab is a well-known manufacturer of ultra-warm down jackets for outdoors enthusiasts. The company has recently added a new jacket to its range – the Rab Infinity Microlight Jacket. This jacket is lightweight and breathable, with a GORE-TEX membrane for water resistance and breathability.

Rab Infinity Microlight Down Jacket

This down jacket is designed for year-round use in the mountains. It is made of 100% recycled down and features a GORE-TEX INFINIUM WINDSTOPPER (r) shell that provides superior protection and breathability. Its lightweight and compact design make it an ideal mid-layer or outer layer.

The Rab Infinity Microlight Jacket is lightweight and has a slim fit that enables you to move freely. It also features a drawstring hood with an integrated brim. If you enjoy mountaineering and want to make your trip as comfortable as possible, this jacket is the perfect option.

Rab Neutrino Pro

Rab’s Neutrino Pro jacket is a lightweight, packable jacket with excellent warmth and weather protection. The lightweight Pertex Quantum Pro fabric is highly breathable. It also features a DWR coating. A sturdy zipper system with Vislon Aquaguard is another attractive feature. The jacket also has a dual-zipper setup that lets you belay without removing your jacket. The down fill is nine ounces of 800-fill power with a hydrophobic coating. Its outer Pertex Quantum Pro fabric and lining are made with recycled materials.

This down jacket is perfect for technical users who require high levels of warmth. The Neutrino Pro’s low weight and packability make it an excellent choice for various outdoor activities, including skiing, snowboarding, and hiking. But at the same time, it sacrifices some valuable features and durability to achieve these desirable traits.

GORE-TEX membrane

The Rab Infinity Jacket features a GORE-TEX membrane and an extra layer of fabric to combat wind and rain. It has stitchless panels protect the torso from wind and rain, and its horizontal baffles provide an extra layer of warmth around the upper body. Unfortunately, the extra layer of fabric makes the jacket slightly heavier.

This jacket is for mountaineers and ice climbers dealing with cold weather and wind. The GORE-TEX Infinity is constructed with a soft GORE-TEX INFINIUM outer shell and a robust WINDSTOPPER membrane. The Infinity also features a Nikwax hydrophobic finish, which helps repel water. In addition, the Rab Infinity features a low-profile zip to protect the lower face. The zipper is designed to allow you to wear a helmet underneath if necessary. The hood is also equipped with a stiffened peak.

Down fill

Rab has manufactured down jackets and other down-filled apparel since 1981. While their original products focused on down sleeping bags and expedition-weight parkas, the brand has since expanded to include a variety of synthetic and down-filled jackets and other outdoor gear. Today, they offer a variety of jackets, ranging from ultra-lightweight down shells to mid-weight and base-layer fleeces.

The Rab Infinity jacket offers added weather protection for your biking and hiking adventures. Its outer shell features a special Nikwax hydrophobic coating to protect the down filling and reduce clumping when damp. In addition, the jacket features a hood that adjusts for a custom fit.


The Rab Infinity Jacket is a high-quality down jacket with a windproof and waterproof construction. It features a Gore-Tex Infinium Windstopper outer filled with 800 FP RDS. The jacket is designed for fast ascents on cold winter days. The jacket is waterproof and breathable with a soft, comfortable fit.

The Rab Infinity jacket weighs 16 oz. and has 7.4 ounces of 850-fill down. This makes it much lighter than similar jackets. For comparison, the Brooks Range Mojave weighs just over a pound, while the Feathered Friends Hooded Helios and Outdoor Research Incandescent weigh close to a pound each.
