I found an Arc’Teryx Sidewinder shell a few years on the discount rack at the local Mountain Gear store. Discount in this case meant it was probably a discontinued model at the end of the season. It was around 50% off and I had my eye on one of these for a while, so I grabbed it and headed to checkout.
It is a Gore-Tex XCR based hard shell. The current model is Gore-Tex Pro. Remember, mine is a few years old. The Sidewinder name comes from the asymmetrical zipper that shifts to the side before it reaches the chin. While I didn’t really have any issues with jackets rubbing my chin wrong in the past, the zipper on this completely avoids my neck and chin, eliminating any possibility of an issue. The model I have does have a hood that rolls into a zippered compartment. Not a huge fan of this, but it does work.
There is a small pocket with a window on the left arm, I assume for a ski pass. Works well for my SAR ID card. A Recco reflector is on the right arm, about the same level as the pocket is on the left. Early this fall, I discovered my daily use jacket had seen better days, so I got ready to find myself a new softshell, but still haven’t found the right one. So all winter, I’ve been wearing this hard shell. And it has been fantastic! The pit zips keep the air moving if I’m moving a lot and it is easy to layer under, so keeping warm enough has not been an issue. I’d love to get my hands on the current model, since it looks like there are a couple more inside pockets, but I’m not giving this one up any time soon.
