Cutan 103g/m2 (100% Recycled Polyamide), Fluorocarbon-free bluesign-approved fabric with Icebreaker recycled polyester reinforced areas The windproofing is excellent and there’s little risk you’ll catch a chill once you’re zipped inside;

All rain pands promise that they’re breathable, but if you’re working hard in humid conditions (and rain is 100% humidity), it’s difficult for sweat to evaporate through a fabric and out into the open. Waist RET (Resistance to Evaporative Heat Transfer) tells you theresistance a material has to water vapour passing through it. The lower the RET value, the less its resistance to moisture transfer and therefore the higher its breathability. By the definition of this standard, an RET of 0-6 is 'extremely breathable' (comfortable worn at a higher activity rate); 6-13 is 'very breathable' (comfy at a moderate activity rate); 13-20 is 'satisfactory' or 'breathable' (uncomfortable at a high activity rate); and anything over 20 is going to boil you in the bag (I paraphrase). The semi-elasticated waist has a simple but effective drawcord adjustment, while ½ length side zips ensure easy on and off over all but the chunkiest walking boots. Velcro ankle adjustment ensures a secure seal around your footwear.Designed for fast and light mountain activities, the Pac Plus Pants use waterproof GORE-TEX PACLITE PLUS technology and feature 3/4 length side zips for easy on and off on the mountain. That ensures solid waterproof performance and reasonable breathability, putting them a cut above cheaper rainpants that use own-brand, PU-based membranes. Inside, they have a taffeta and mesh drop liner to protect the Gore-Tex membrane and wearer aid comfort. As a result, they rarely get clammy, though they might get a little warm.

Its 2.5 layer construction laminates a tough outer fabric onto the Gore-Tex membrane. Instead of using a third layer under that (as per 3L Gore Pro, for instance) the membrane is given a protective inner coating, which constitutes the nominal half layer. For Paclite Plus, Gore add another abrasion-resistant treatment that's designed to boost the fabric's durability. In practise this means it should be tougher than plain Paclite, though not as burly as Pro.

Starting at the top, you have an elasticated waistband with an adjustable drawcord allowing you to adjust the trousers to your desired fit. Down the side of each leg is a 3/4 length two-way YKK Aquaguard zip, giving you easy access into and out of the trousers, as well as allowing you to partially unzip them for extra ventilation. The articulated knees and diamond gusset allow for freedom of movement which is particularly important when you’re out scrambling. The bottom of the trousers have a press stud ankle adjustment making them compatible with larger boots. The Pac Plus XT Pants can also be worn with a pair of Montane Braces for extra support.
