Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

Arcteryx Womens Gamma SL Hoody Immersion

Season:Sale

Brand:Arcteryx

Code:28211-IMM

What is the Gamma SL Hoody?

The Gamma SL Hoody is a lightweight, stretchy, comfortable and weather-resistant softshell which can be used for virtually any outdoor activity. The brilliant fit, versatile fabric and array of useful features make it suitable for walking, trekking, scrambling, climbing, everyday... the list goes on!

What is it made of?

The Gamma is made from 87% nylon and 13% elastane; Arc'teryx calls it Fortius DW. As mentioned above, Fortius is super stretchy, durable, comfortable next to skin, water-resistant and wind-resistant, making it one of the most versatile fabrics available for spring/summer use.

What are the features?

Starting at the top, an adjustable, helmet-compatible StormHood provides extra protection and fits nicely over a helmet when climbing or scrambling, yet can be cinched down to fit your head without a helmet. Two zipped hand pockets store everyday essentials, while low profile elasticated cuffs sit nicely under gloves. An adjustable hem drawcord seals in warmth around your waist.

How does it fit?

The Gamma SL features a slim yet unrestrictive fit. Length-wise, it sits on the hips and fits into Arc'teryx's 'trim' fit block, so expect it to be a little snugger than their 'regular' fitting garments.

Where does it fit in the layering system?

The Gamma is primarily designed to provide protection as an outer layer, however, you can stick an insulated jacket over the top when stationary to provide extra warmth.
