Warm hand wash for best garment life. Use pure soap or mild detergent. We have tested and recommend Lux flakes, Sunlight soap, or Persil Sensitive. Lux and Sunlight soap need to be fully dissolved in hot water before converting it to warm. Do not use bleach. Rinse well to remove all residues. Do not wring. Drip dry in the shade to minimise UV exposure. Do not tumble dry. Cool iron may be used to rejuvenate the exterior DWR* coating. Do not dry clean.

Keeping waterproof breathable garments clean will increase their lifespan. During normal wear, dirt, salts and oils from contact with the skin will accumulate on the inside surface. This will show as a dark stain on the mesh, especially around the neck and hood. If left over an extended period of time, this may contaminate the laminate or coating and cause irreversible damage to the jacket. To prevent this happening the garment should be washed at least once a year and more often if worn regularly. Hanging up garments in dry well ventilated areas will prevent mildew building up on the fabric’s underside. Avoid all contact with solvents and chemicals, accidental contact should be washed off as soon as possible.

Waterproof/Breathable Fabric Performance Overview:

To ensure your garment breathes to its full potential it is important to maintain the water repellency of the outside surface. It is also important when you are physically active to wear as many non moisture absorbing layers as possible underneath the jacket. If you wear natural fibres (merino or cotton) keep them as light as possible and reduce the number of layers you use. For maximum breathability we recommend faster drying non moisture absorbing polyester fabrics for your thermal layers.

All waterproof breathable fabrics require regular cleaning. Jackets should be washed once a year and if worn regularly, you should wash them more often than this. A jacket may look clean on the outside but the most harmful contamination occurs from direct skin contact. The neck and hood regions are the most susceptible to this. Over time contamination from the skin will weaken the glue that holds the laminated layers together or the bonding between a coating and its outer fabric. This can cause irreversible damage and reduce the functional lifespan of the garment. Two-layer fabrics with an exposed underside are very susceptible to this and need more cleaning than three-layer fabrics. There is no need to overwash your waterproof garments. A quick hand wash of a jackets neck and hood region maybe all that is required to maintain its cleanliness and prolong it's life. Wearing collared garments or bandanas around the neck reduces the risk of contamination and the need to clean the garment as often. If the primary use of the jacket is to be worn while carrying a heavy backpack we would recommend using the heavier more durable mesh backed three-layer fabrics.

* DWR is the Durable Water Repellant coating on the outside of the garment’s face fabric. It is an important part of the garment’s performance as it allows water to bead off the surface. This maximises the breathability. DWR coating is applied as a specialised process during the manufacturing of the fabric. Over time it can wear down. When this happens the outside fabric will ‘wet out’ making it feel cold and clammy. In this state breathability is impeded.

The DWR can be rejuvenated by the use of a cool iron after washing. After extended use, a complete re-application of this will enhance the performance of your jacket. We have developed our own DWR treatment, a solvent based, environmentally friendly, flouropolymer spray called Gecko Guard. After testing water based DWR products we decided we needed a more durable, more effective product for our garments. We believe Gecko Guard is the best aftercare DWR treatment available.

Solid, Light, Dependable
After 18 months fairly solid use in the Invercargill weather the Adrenaline has surpassed my expectations.

So what has it been used for? Pretty much everything from 3hr bike interval sessions to mountainbiking to watching the Phoenix actually win a game!

During high intensity sessions I noticed a build up of moisture on the inside. I have to stress a couple of points here- 1. by high intensity I mean interval sessions on the bike or tempo runs (4-4.15 min/km pace). 2. I sweat a lot when I exercise. This meant often my back and shoulders would still end up wet when I had finished training. Opening the pit zips helps a little but not much. The reality is even my Spoke jacket ends up sopping wet after these sessions.

During low - moderate intensity exercise it is a different story. I remain warm and dry inside and out! The only caveat is if I have a pack on then my shoulders and back where the straps and pack run can get a bit damp. Basically the straps prevent the jacket breathing efficiently.

This was exemplified the other day during a MTB ride- Chest area nice and dry, shoulders and back damp from wearing my hydration pack. Further, I threw it in the wash only to discover my speedo and camera went through the wash too. Both came out BONE DRY. Not a single drop of water got into the pocket!

Keeping warm and dry was my first priority for the jacket, second up was packability. The Adrenaline ticks this box as well, scrunching down to next to nothing meaning it can live in my pack for commuting or form part of my 'Required gear' during the likes of the Motutapu event.

As an Earth Sea Sky garment; style, build quality, finishing and durability were not concerns that I had for the Adrenalin as these qualities are endemic in all ESS kit.

If there is any change I would make to the Adrenaline it would be to make one of the zips double sided enabling it to be packed into itself.

After 18months use and abuse my Adrenaline hasn't missed a beat and I would recommend to anyone. Review by Brook / (Posted on 13/01/2014)
Good offering in the ultra light weight category of jackets
The Adrenaline as a featherweight multi-activity jacket, designed for adventure racing, multisport or any activity in which grams matter. It is constructed from Entrant DT2.5 fabric. DT stands for ‘dry touch’ and refers to the half layer, which is really just the inside surface being slightly raised so as to avoid clamminess and the need for the traditional third layer of shell fabric. At 450 grams, it is planted firmly at the breathable/lightweight end of the spectrum.

To test the breathability, rated at 8,000g/m2/24hr, I donned it for a walk up Shadow Basin at the Remarkables Iced and Mixed Festival. To test the waterproofness, rated at 10,000mm, I walked to the supermarket and back in a pouring southerly. In-between times, I used it for ski touring, biking to work and on-piste skiing. It performed well. Rain didn’t get in and a lot of sweat got out. Simple.

With regard to features, it has a lot going for it. The hood is roomy, adjustable, has a visor-wire and turns with your head. My preference would be for it to be permanently attached, but I understand that others prefer the option of taking it off. The elasticated cuffs have a perfectly adequate velcro closure and the zips are waterproofed. Gusseted shoulders mean you can reach with your arms up, around and across. It is perfect for athletic mixed climbing moves or pointing up at the menu at your local café.

The objective of reducing weight has been ruthlessly pursued. You don’t get a fluffy chinguard muff, for example. The chest pockets and underarm vents use the same zip on each side, which takes a bit of getting used to.

The configuration of the pockets is my only, and minor, criticism. I am not sure if there is a solution for this, or if it can be achieved without increasing weight, but I think it is natural to access chest pockets from across the torso with the opposite hand, rather than crooking your elbow and shoulder to access a pocket that can easily be confused with the underarm vent. First world problem, I know.

This jacket does need to be washed regularly and I am assured that its performance will hold up to regular washings and prolonged use. However, I wouldn’t take it into the bush and I wouldn’t want to rough it up against rock or icy snow.

If you are really keen on stripping grams it is well worth a look. Review by Sam / (Posted on 8/10/2013)
