Arcteryx Mens Beta AR Jacket Neptune

Season:Sale

Brand:Arcteryx

Code:21782-NEP-

What is the Beta AR?

There is a reason that the Beta AR has been part of Arcteryx's essentials range for nearly 20 years. Strong yet breathable, robust yet supple, durable yet light; the Beta AR has been completely redesigned for this season to encompass everything Arc'teryx has learned from making waterproof jackets for almost 30 years. Everything about this piece (the fit, the materials, the construction and the features) comes together to give you this incredible fortress of a jacket that can be grabbed straight off the coatrack and taken with you on any adventure you have planned.

What is it made of?

This superb lightweight all-rounder is made with a very durable yet supple ripstop 40D Nylon outer in the main body with 80D Nylon reinforcements in the high wear areas (e.g. Shoulders). This durable face fabric encompasses a 3L Gore-Tex Pro membrane that's windproof, waterproof and highly breathable. 

What are the features?

Moving onto the features of the jacket; we briefly touched on the adjustments of the hood so let's expand on that first. The hood is Arcteryx's own helmet compatible DropHood design, which is basically a fully standalone collar with a separate hood. It can be cinched with one-handed drawcords, allowing it to rotate with the head without obstructing your vision when turning your head from side to side. The high neck means that the jacket will still protect your chin and neck from cold winds, even when the hood is down. When you need to dump heat quickly (like when you're pushing hard to get to the top of a mountain) then unzip the handy WaterTight pit zippers. The toggles on these zips are generously sized without adding a tonne of weight so you can still easily get to them with big gloves on. Storage wise, the jacket features two large hand pockets in the front of the jacket and one internal, zipped security pocket. To seal out the elements Arcteryx has used adjustable hem drawcords, a WaterTight centre front zip and Cohaesive cord locks in the front hood adjusters, as well as improving the shape of the neck so it sits closer to your collarbones, all with the aim of sealing out rain, snow and cold drafts. 

How does it fit?

The revamped Beta AR has a longer hip length for better coverage, a slightly roomier fit so you can fit more layers under it and improved e3D (ergonomic 3D) patterning that provides an enhanced level of articulation and movement. The Beta AR is roomier than the Beta LT to allow you to fit more layers underneath in colder conditions; it also features plenty of room in the shoulders for active climbing and mountaineering use. 

Where does it fit in your layering system?

The Beta AR is designed to be your outer layer when the weather isn't on your side (unless you like rain, in which case when it is on your side). Other layers can easily fit underneath, but the Beta should always be used as your protective outer layer.

Care and maintenance

To keep your outdoor clothing and equipment in tip top condition and performing to its maximum we recommend the use of Nikwax products. We have been using Nikwax products since day one (26th March 1986) and have found them to be totally reliable, dependable and effective. Today’s Nikwax treatments contain environmentally friendly elastic water-repellent polymers that bond to fabric fibres, leaving the spaces between open and breathable. These stretchy polymers are able to stretch and move with the fabric so they stay put for longer and work better.

Nikwax treatments will not change the look or feel of the fabric and they are all water based, environmentally safe, non-flammable and contain no nasty Fluorocarbons. Nikwax products can be used to clean, re-proof and revitalise all your outdoor technical clothing and equipment.

Waterproof breathable clothing has a durable water-repellent (DWR) finish applied to the face fabric during the manufacturing process. The DWR forces water to bead up and roll off the surface therefore preventing the fabric from absorbing moisture. If the outside of your jacket is soaked in a layer of cold water, the warm damp air within can’t escape and will condense on the inside. This makes the jacket feel cold clammy and can make you think that it’s leaking. The DWR finish is not permanent and needs to be maintained and revitalised to optimise performance.

This three layer waterproof jacket should be cleaned regularly with Nikwax Tech Wash; I wash my jacket about once a month, or more often if it gets really filthy. Regular washing with Tech Wash will maintain the DWR for longer and remove salts and oils that can contaminate the fabric, and it will keep your lovely jacket clean and smelling fresh. Washing can be done in a machine according to the manufacturers care guidelines (on the internal label). First clean out any detergent and conditioner residue from the machine dispenser and then add the required amount of Tech Wash and away you go. Hand washing is also suitable but be sure to rinse the garment well.

When you notice that rain/water is no longer beading up and rolling off it’s time to re-proof. Nikwax TX Direct will re-instate a long lasting DWR to completely rejuvenate your jacket. Re-proofing can also be done in the machine once a garment has been washed. Just add the TX-Direct and use the same programme you used for washing. You can also use the spray-on product on a damp garment that has just been washed.

You wouldn’t buy a Ferrari and never have it serviced, so make sure you regularly wash and re-proof your quality kit.
