Gear Review- Black Diamond First Light Hoody

For the last couple months I’ve been testing the Black Diamond First Light Hoody. From early season recon missions into Tuckerman Ravine searching for climbable November ice to blustery cliff top rigging work while creating an instructional video with Northeast Mountaineering I’ve cultivated some appreciation for the versatility of this “light puffy”. Lightly insulated hooded jackets like this are a great addition to almost any climber or skier’s kit. If you are looking for a full on winter belay jacket you can check out some other models I am reviewing here.

The Black Diamond First Light Hoody uses 60 gsm of PrimaLoft® Silver Insulation Active with a traditional tube style baffling. This is a high end insulation that resists “migration”; basically it stays put within its baffles reducing gaps in protection. PrimaLoft® also claims it is more wind resistant but less thermally efficient than the PrimaLoft® Gold Eco.

So this type of PrimaLoft insulation isn’t as close to high loft down in terms of heat retention per weight but feels quite warm for the weight of this piece. It also boosts excellent breath-ability and will still retain heat if you get soaked in a “not quite full winter” rain event.

The Black Diamond First Light Hoody uses Schoeller® stretch-woven nylon with NanoSphere® Technology (80 gsm, 93% nylon, 7% elastane). This is a highly breathable shell fabric which allows this jacket to stay on during high output effort in cold conditions (skinning with sub-zero ambient temps) without overheating. In hand the shell fabric feels like it will handle abrasion better than some others in this category. The nylon woven mesh liner adds a bit of weight to this piece (65 gsm, 100% nylon) but is super soft and feels great directly on skin.

Manufacturer specs state 510 grams, 18 oz. My home scale on my size large reads 568 grams, 20 oz. The jacket compresses easily enough into its internal chest pocket and only appears to be slightly larger in packing size than the Nano Puff (but about 50% heavier).

A carabiner sewn loop allows you to clip this off to the back of your harness if you are leaving your pack on the ground and the top of the pitch looks a little bit more breezy than the base of the route.


I found the sizing to be spot on. I went with a large which fits my 42 inch chest, 180lb build, with a little extra space for a soft-shell and base-layers but not too baggy to throw on over a t-shirt. The hood is sized to fit perfectly over your helmet.

Yet another fantastic option in the growing lightweight hooded jacket category the Black Diamond First Light Hoody is an ideal “just in case” piece for edge season climbing and an obvious go-to choice for hard & fast winter objectives. If sharing leads on a multi-pitch ice climb I would still bring a full duty belay jacket like the models I am reviewing here. If you haven’t added a “light puffy” to your kit yet or the one you have needs replacing this should be on your radar.
