Rab Infinity Light Jacket Review

5

The Rab Infinity Light is an incredibly lightweight, GORE-backed mountain climbing jacket. It is priced at around $575 and has features that make it an excellent choice for climbers. It has fully-baffled construction, a GORE-TEX membrane, and sewn-through construction. In addition, this jacket packs down small enough to be compacted and carried on your back.

Sewn-through construction

The Rab Infinity Light Jacket is a mid-weight down jacket. It weighs just 16 ounces and contains 7.4 ounces of 850-fill down. This weight is significantly lower than other parkas, including the Brooks Range Mojave, Feathered Friends Hooded Helios, and Outdoor Research Incandescent.

Although sewn-through construction is lighter and saves on weight, it is less warm than box-baffle construction. This type of construction results in more individual baffles and seams, which can let heat and water seep through the fabric. However, the sewn-through building is less likely to be prone to heat loss than box-baffle construction.

Down jackets are also insulated with baffles to keep the warmth inside. Box-wall baffles are generally better for warmth, while sewn-through baffles pack down too much, leaving cold spots.

GORE-TEX membrane

The Rab Infinity Light Jacket GORE-TEx membrane is a versatile layer for all weather conditions. Its 800-fill down fill is twice as thick as a Patagonia Down Sweater and is coated with a fluorocarbon-free waterproof solution. This unique solution developed by Rab and Nikwax adds a layer of protection to the down. The Rab Infinity also features a GORE-TEX membrane and a waterproof face made from 13-denier nylon fabric.

Rab has created the Infinity Light Jacket for mountaineers who must perform in mixed weather conditions. The Infinity Light Jacket’s lightweight construction enables it to pack in a stuff sack and is ready to use on the mountain. Its GORE-TEX INFINIUM membrane protects the down and offers maximum breathability. The lining is made from high-quality 800-FP hydrophobic goose down and is water-resistant.

Fully baffled

This jacket is sewn through, not baffled, to reduce weight and increase warmth. The interior strips of fabric between this jacket’s inner and outer shell prevent it from migrating, and the jacket retains its ability to keep you warm when wet. The difference between the two types of baffles is only a few ounces, so both versions are good options for those who want maximum warmth.

The Infinity Light Jacket uses 800-fill down. That’s double the fill of a comparable Patagonia down sweater. The down is then coated with a fluorocarbon-free waterproof solution. Rab teamed up with Nikwax to develop this waterproof solution, which adds a layer of protection against the elements. In addition to this, the jacket has a GORE-TEX waterproof membrane and a 13-denier nylon face.

Packable

The Rab Infinity Light Jacket is a lightweight, packable down jacket with a GORE-TEX inner lining. It works well in any weather, including cold. It is also highly insulated, with 800-fill power down for added warmth while belaying. The jacket is also easy to pack and includes a stuff sack. It starts at $575.

The Rab Infinity weighs 16.4 oz. And has 7.4 ounces of 850 fill down, making it a highly insulated and waterproof jacket. It weighs nearly half as much as some competitors, including the Feathered Friends Helios and Brooks Range Mojave, which are close to a pound each.

Weight

The Rab Infinity is an excellent choice if you’re looking for a lightweight, warm jacket for winter rock climbing or all-day alpine adventures. At only 16 ounces, it is one of the lightest down-filled jackets on the market. In addition, it weighs less than half as much as the Marmot Biggie.

The Rab Infinity Light Jacket is made of ripstop and nylon material and is lightweight and breathable. It has a two-way YKK Vislon zip with a synthetic insulated baffle. It also has two zipped hand pockets and an internal zipped security pocket. While lightweight, it offers excellent breathability and protection against wet weather.
