What are the Beta AR Pants?
Where to start? Well, if you want a pair of lightweight, low bulk, waterproof overtrousers then look no further. The Arc’teryx Beta AR pants are a beautiful example of what waterproof overtrousers should be. Perfect for 4 season, all-round use in outdoor activities such as skiing, walking and mountaineering.
What are they made of?
Arc'teryx use an ultra-tough 80D nylon to construct the main bulk of the trousers. This features a durable water repellent coating and is one of the most durable fabrics Arc'teryx use. Behind this, a Gore-Tex Pro Most Rugged membrane provides unbeatable waterproof and windproof protection for severe conditions. For added durability around the instep you get Schoeller Keprotec patches for reassuring protection against boot damage, crampons and skis. Made from high tensile aramide fibres, this stuff is designed to take a battering and will last for years. The elasitacted hems feature internal Cordura® Powdercuffs and a bootlace hooks for extra protection during snowy alpine days.
What are their features?
Arc’teryx pioneered the industry’s Watertight zippers which seal out the nasty weather — on the Beta AR Pants you will find these on the ¾ length side zips, pockets and fly. Arcteryx have used 3/4 length zips so that they don't interfere with a climbing harness or rucksack hipbelt whilst still allowing full and easy access. All the seams have a 1.6mm micro seam allowance in order to reduce bulk and weight whilst improving overall breathability; thinner seam tape equals less weight plus a larger area of breathable fabric. Other features include an adjustable webbing belt, suspender loops, a zipped hip pocket and a hidden Recco reflector. If the worst should happen, this reflector will give an approximate location if scanned from above.
How do they fit?
The fit of these trousers comes under the Arc’teryx “regular fit” design, which is basically their standard fit. The complex patterning of the Beta AR pants allows for an exceptional articulated fit, providing a great range of movement and means less bulk by eliminating any excess fabric. The Beta AR Pants have enough room underneath for additional layers should you require extra warmth.
