"My favorite, warmest belay jacket for ice climbing!"
This is hands down the warmest and most comfortable jacket for belaying during ice climbing on cold, cold days. It is the warmest jacket I own and huge but amazingly packs down to a relatively small enough size to hang off your harness. All the fabric reinforcements on the shoulders and arms are perfect for longevity since it is virtually impossible to poke a hole or rip the fabric. I also love the red color and it is so toasty to use for any super cold activity when you aren't moving a lot (bonfires, in your car changing clothes on the side of the road after xc skiing).
