How do you remove over FOUR pounds from a layering system and increase performance?
ANSWER: FABRIC & TECHNOLOGY
I was hoping to remove two pounds when I developed the KUIU line when compared to my work at Sitka. Four pounds surprised me.
Ounces matter for climbing mountains. Ask any professional bike racer how much they spend to save an ounce. Every ounce eats up kilos, the lighter your set up, the better you will feel, especially over a 10-day hunt. This mentality dominates professional mountaineering and cycling.
There is no reason ounces should not be just as important to mountain hunters. There is nothing smart about carrying a 90lb pack unless you are required to.
Founded in 1926, Toray is a leading chemical manufacture based in Osaka Japan. Toray fuses nanotechnology into its operations, using organic synthetic chemistry, polymer chemistry and biotechnology as its core technologies. Using Chemistry to solve industries most challenging problems, Toray operates leading divisions in medical, chemical, carbon fiber and textile industries. Toray leads the textile industry in new technology developments in all three major groups of synthetic fibers-nylon, polyester, and acrylic fibers. Toray is setting new standards in waterproof breathable laminates and durable water repellency (DWR).
Primeflex Spiral Yarn
Toray’s development of the patented Primeflex yarn increases fabrics durability, decreases weight, dry-time, and stretch-recovery over time. Primeflex fabrics use a patented spiral yarn technology, allowing for the yarn to stretch and recover without using elastic such as lycra or spandex. Elastic is heavy, hydrophilic (attracts water) and has a limited life expectancy. Toray’s Primeflex fabrics are lighter weight with much better performance and durability than competitive fabrics.
KUIU is exclusively using Primeflex fabrics for all of its outwear, which is a key ingredient to saving 4 pounds in the layering system. The Primeflex fabric collection is a range of 100% Poly fabrics that include stretch woven, soft shell and waterproof breathable fabrics.
Toray has developed the highest rated 4 way-stretch waterproof breathable laminate available, which has an unmatched 20,000mmH2O/20,000g/m2 24 Hour rating. This allows for a maximum waterproof and breathability and stretch in one package. This is a performance level only KUIU has introduced to the hunting industry.
Durable Water Repellency
Kudos XR is a new DWR developed by Toray has reset the standard in durability and performance. Kudos XR DWR performs better and last significantly longer. DWR is critical for waterproof breathable face fabric. If DWR fails the face fabric “wets out” causing condensation build up on the inside of the garment.
Compared to a conventional waterproof coatings that are applied over the fabric’s entire surface, Toray’s Kudos DWR finish is actually applied to every individual fiber to allow the fabric to have better air permeability to eliminate stiffness.As you see from Toray’s supporting data, not all DWR’s are the same.
Water Resistant Down
Through nanotechnology, Toray has created a water repellent finish for down feathers called Quixdown that makes a feather essentially waterproof. Toray’s Quixdown now eliminates the need for synthetic insulation which is significantly heavier, bulkier and not nearly as warm as down.
As I stressed in my previous Branded Fabric post, it is important to understand what you are buying. Today, most “technical” gear is rarely made using the best fabrics and technology available. Competitive price pressures have forced most brands to cut corners and move away from companies like Toray to less expensive fabric knock offs. There is a very big difference.
By partnering with Toray, KUIU continues to market products with a higher performance level so you can get more out of you on tough mountain hunts. Four pounds is just one result.
I look forward to your thoughts and feedback regarding this information.
