Gear Review- Big Agnes Dunkley Belay Jacket

The Big Agnes Dunkley Belay Jacket is the lightest synthetic belay jacket I have tested this season that also competes well in the heat retention department. I previewed this jacket back in November and now that I have tested it above treeline on Mount Washington and while hanging at icy cold belays while ice climbing throughout the White Mountains I am ready to share some more first hand opinions on this piece.

Let’s start with the most important feature:

Warmth

The Big Agnes Dunkley Hooded Belay Jacket uses 120g of Pinneco Core™ fill in the body and 80g in the sleeves. This “feels” warmer and puffier than the Primaloft ECO insulation used in other jackets I am testing and has decent compress-ability. I wore this over my typical soft-shell and Merino wool layers on Mount Washington in 60+mph winds with wind chills hovering around -40 degrees and was very pleased with the protection it offered. Yesterday after topping out a remote back-country Grade 5 route off the Kancamagus Highway I was grateful for the full enclosure insulated hood while I was stationary and exposed belaying both a photographer and my partner for the better part of a windy hour. Here’s some video from that climb:



Shell

Big Agnes does not list much detail in relation to the shell fabric, just: “100% recycled polyester shell is wind-proof and water resistant”. I have reached out to Big Agnes for more info and will update this as soon as I hear back! That said I found it fully windproof. It is likely there is a DWR treatment on the fabric as climbing under a drippy chandelier of ice a week ago the jacket did not take on any moisture.

Weight/Compress-ability

24.5 oz. / 695 grams. The lightest option in this seasons line up of synthetic belay jackets this piece easily stuffs into an included high quality 10 x 7 stuff-sack. Oddly the manufacturer’s website description references an interior chest pocket that doubles as a stuff sack but I believe this must be a web error as there is no interior chest pockets and the exterior chest pocket is far to small to function as a reversible stuff sack.


Fit

I went with a size large for my 42 inch chest and it fits great over my typical load out. The adjustable hood is the perfect size for my helmeted head. Arm length is slightly shorter than similar models and the back length feels slightly shorter, which works well over my climbing harness. If in doubt consult the manufacturer’s size chart!

Summary

The Big Agnes Dunkley Belay Jacket is a solid choice for a synthetic belay jacket, a must have item in every ice climber/mountaineer’s kit. I like the high visibility yellow but it also comes in a visible bright blue if yellow isn’t your thing. It comes in black too but I would not recommend that color for a belay jacket (bright colors are happy colors when you are freezing your tuchus off). If you’re in the market for a solid performer in the belay jacket you can pick this one up here at a great price.

See you in the mountains,
