What is the difference in fabric performance between the 3LT JACKET and the PERTEX® 3LT SHIELD JACKET?
With two waterproof outerwear items that have similar names, it is difficult to compare how their fabric materials and waterproof specifications differ.
The PERTEX® 3LT SHIELD JACKET features a nylon outer fabric with a water resistance of 20 000 mmH₂O, while the 3LT JACKET has a polyester outer fabric with a water resistance of 7920 mmH₂O.
The two outer garments from FEATHERDOWN differ starting from the fiber used in the outer fabric. The 3LT JACKET uses a 30D 3L SHELL fabric woven from 100% polyester as its outer fabric[1]. On the other hand, the PERTEX® 3LT SHIELD JACKET uses PERTEX SHIELD fabric made of 100% nylon for its outer fabric[2].
Differences also appear in specifications handling water pressure and moisture. Generally, water resistance refers to the degree to which a fabric withstands water pressure, and breathability refers to the ability to expel internal moisture to the outside. The 3LT JACKET features a water resistance of 7920 mmH₂O and a water repellency rating of Grade 4.5[3]. The PERTEX® 3LT SHIELD JACKET has a water resistance of 20 000 mmH₂O and a breathability of 28 000 g/m² · 24h[4][5].
The breathability figure of the 3LT JACKET and the water repellency grade of the PERTEX® 3LT SHIELD JACKET have not yet been confirmed in official materials.
