What is the Infinity Jacket?Back for this season with an updated fit and now with a fully recycled lining! The Rab Infinity Jacket is a natural goose down heavily insulated and highly weather resistant jacket for mountaineers and hill walkers looking for maximum warmth with high levels of breathability and protection from all but the worst of the weather.
Rab have used the new Gore-Tex Infinium membrane to protect the down from the elements, and whilst this does not make the Infinity 100% waterproof, it does make it incredibly breathable and to be honest, you’d have to try pretty damn hard to get wet in this jacket.
What is it made of?Insulation: Let's start with the beating heart of the Infinity Jacket, the insulation. Rab have used 250g of 800 Fill Power, Hydrophobic, RDS European Goose Down in a box wall construction to maximum the down’s ability to loft.
Ok, let’s break that down:
Fill power - Fill power measures the warmth and efficiency of the down, alongside its ability to loft/fluff up. A rating of 800 fill power means that 1oz of this down fills 800 cubic inches of space when fully lofted. For a full explanation, you can check out our YouTube video on fill power by clickinghere.
R.D.S - The Responsible Down Standard ensures that the down is sourced from happy birds who haven't been plucked and have been well cared for.
Hydrophobic - Hydrophobic down dries out and lofts quicker, resisting moisture from sweat that may build up as you're warming up inside the jacket. Fluorocarbon-free Hydrophobic finishes don't use harmful chemicals that cause damage to the environment - a bonus for more eco-conscious adventurers.
European Goose Down – Just about the best quality down you can get!
Box wall - Box-wall construction uses distinct box-shaped compartments that run horizontally around the body. Because the box-shaped baffles are not pinched at the edges there is space for the down to fully loft throughout the chamber allowing for an even distribution of down and vastly reducing the likelihood of cold spots.
Surrounding all this luxurious insulation is the new Gore-Tex Infinium Windstopper membrane. This new membrane provides complete wind-proofing, high levels of breathability and excellent weather resistance. Technically this membrane isn't 100% waterproof, but in practice we've found that only prolonged torrential rain will eventually seep through.
On the inside a 20D recycled lightweight, breathable nylon is used which increases next-to-the-skin comfort and on the outside Rab have used a lightweight, ripstop nylon for increased durability and protection. Additional stitch-free overlaid panels on the torso and upper arms, provide extra protection in harsh conditions.
What are the features?Starting at the top, the Infinity features a helmet compatible, down insulated hood with a wired peak and concealed adjusters to seal in the warmth around your face. This feature makes the Infinity Jacket the obvious choice for full on winter mountaineering.
Moving down, you've got articulated sleeves for increased comfort when climbing, finished off at the cuffs with Velcro adjusters to get a tight seal over gloves or mittens. The front zip is a two-way Vislon Aquaguard for increased weather protection and reliable performance even in freezing conditions. This zip is then backed up with a synthetic insulated baffle to make sure nothing gets through.
Storage wise, you get two zipped hand pockets, a YKK Aquaguard zipped chest pocket, perfect for guidebooks or maps and two internal mesh dump pockets for water bottles or hats and gloves. Down at the bottom of the jacket is a hem drawcord to seal out the weather and keep in the warmth and for extra safety there are reflective logos.
An included stuffsack makes storage easy and the Infinity will easily pack down into your pack when not required.
How does it fit?The Infinity Jacket fits into Rab's Relaxed fit block which sizes up fairly large. This is to allow layers to fit underneath in super cold conditions, but also to allow complete freedom of movement when mountaineering.
Where does it fit in the layering system?The Infinity is designed to be your outer layer in extremely cold and damp conditions. Thanks to the Gore Infinium membrane, Hydrophobic Down and protective outer fabric, you're unlikely to ever need to wear a shell jacket over the top.
