Black Diamond Deploy Down 0.5 Full Zip Hoody Evaluation

Backside Line

The Black Diamond Deploy Down 0.5 Full Zip Hoody (males’s / girls’s) is actually for the ounce-counters and quick movers. This puffy isn’t simply gentle, it’s the lightest down jacket we’ve ever examined. Black Diamond even calls the pullover model “the lightest down jacket on the earth,” and after carrying it on numerous chilly mornings throughout Colorado’s excessive nation, we imagine the hype.

Initially, the load grabbed our consideration, however it’s the heat, options, and considerate design that maintain it in our packs. Regardless of its feathery construct, the small quantity of 1000-fill down traps warmth remarkably properly, making it good for chilly begins, summit breaks, or layering beneath a shell. The match is slim and athletic however comfy, permitting for straightforward motion with out feeling too restrictive.

After all, ultralight comes with tradeoffs. The paper-thin 4D stretch shell cloth must be handled with care; it’s not meant for bushwhacking or actually any sort of abrasion. However for ounce-conscious adventurers who worth efficiency and packability above all else, this jacket is difficult to beat.

How We Examined

We examined the Black Diamond Deploy 0.5 Full Zip Down Jacket over two months in Colorado’s crisp early-fall situations. This ultralight puffer got here alongside for all the things from day hikes in White River Nationwide Forest to path runs close to Boulder’s Flatirons and an alpine begin on the Monarch Crest Path.

We additionally wore it throughout chilly pre-sunrise fishing periods at Jefferson Creek, CO, and through damp, brisk mornings within the Appalachian Mountains of western Maryland. Via all of it, we centered on heat, packability, and sturdiness to see how this featherweight jacket carried out when temperatures dropped and the miles stacked up.

Consolation

When speaking about probably the most comfy jackets in our lineup, we wouldn’t essentially embody the Deploy Down 0.5. That’s to not say it’s uncomfortable. It’s simply solidly middle-of-the-road by way of coziness. Consolation isn’t actually the principle objective of this jacket, however each producer retains it in thoughts when designing gear.

Beginning with the positives, the elastic cuffs are tender and unobtrusive, and the insulated collar and handwarmer pockets do a pleasant job of including heat. Jackets this light-weight can typically have that crinkly, “trash-bag” really feel to the outer cloth, however the Deploy’s materials feels smoother and softer in opposition to naked pores and skin than we anticipated.

The general match is athletic and slim. We advocate attempting it on earlier than shopping for if attainable. Our lead analyst, who’s 6’2″ and usually wears a big, discovered this jacket only a bit too trim and would take into account sizing up. The slim reduce is intentional; it’s designed to make layering over prime simpler. One small gripe: the jacket is on the shorter facet. When our analyst lifted his arms (like whereas climbing), it rode up and stayed there. When you’ve got a slimmer construct, although, the match will probably be spot-on.

Heat

With a jacket this light-weight, regardless of what advertising and marketing would possibly declare, you’re usually buying and selling a bit of heat for packability and weight financial savings. That’s nonetheless true with the Deploy Down 0.5, however it performs impressively properly for its weight class. It’s filled with premium 1000-fill-power goose down, which offers wonderful loft and warmth retention although there isn’t a lot of it.

The slim match, elastic cuffs, comfortable hem, and insulated collar and handwarmer pockets all work collectively to entice heat near the physique, making this jacket surprisingly cozy for the way gentle it’s.

Would we advocate it for lengthy, shady belays or sub-freezing nights? Probably not. However as a light-weight emergency layer for backpacking, alpine begins, or climbing missions the place each ounce issues, it’s a standout selection. We consider it as extra of a quasi-active insulation piece, good for conserving your core heat on the transfer or whereas ready for the solar to rise within the excessive nation.

Weight & Packability

The Deploy is the lightest jacket we’ve ever examined, severely. Our measurement giant weighed in at simply 5.9 ounces, which is absurdly gentle for a down piece. Once we first picked it up, we genuinely thought the model tags would possibly weigh greater than the jacket itself. They didn’t, however the truth that it even crossed our minds says quite a bit.

The Deploy Down 0.5 simply packs into its personal pocket, and we imply simply. It virtually folds itself. As soon as packed, it’s smaller than a Nalgene and may be stuffed nearly wherever.

The lightness can be noticeable whenever you’re carrying it. If it weren’t for the heat and trim match, you’d barely realize it’s there. For reference, our tester’s iPhone weighs almost twice as a lot as this jacket. If we’ve one minor gripe, it’s that the packed measurement might compress even additional (virtually half the scale of the stuffed pocket). For enjoyable, we truly hiked with it in our pants pocket simply to show it’s attainable. 5 stars throughout.

Climate Resistance

We wouldn’t take into account the Deploy Down 0.5 a storm-worthy jacket with out a shell to go over it. The ultrathin 4D outer shell cloth does an honest job blocking gentle wind, however in really blustery situations, you’ll wish to layer it beneath a correct shell for added heat and safety. Like most high-end down items, it’s handled with a DWR (sturdy water repellent) end and crammed with HyperDRY water resistant down to assist it shed gentle moisture.

That stated, anybody accustomed to down insulation is aware of these therapies solely delay the inevitable. As soon as the outer cloth begins to soak via, efficiency drops shortly. Throughout testing, we discovered that the skinny shell gave option to moisture comparatively quick, even in gentle to reasonable rain, and the down started to moist out quickly after.

This piece isn’t constructed for storm protection; it’s meant to be a part of a layering system. So long as you pair it with a water-resistant shell when situations flip nasty, it performs precisely as meant.

Breathability

On the subject of breathability, the Deploy Down 0.5 isn’t precisely constructed to let air circulation freely, however that’s not likely its objective. The slim, athletic match hugs near the physique on the cuffs, hem, and collar, which helps entice heat however limits air flow. Not like technical shells that characteristic pit-zips or mesh-lined vents, this jacket depends completely on its light-weight cloth to manage warmth, which works to a level however isn’t supreme when you’re pushing laborious uphill.

Throughout testing, we discovered that the Deploy breathes okay for a down jacket this gentle. The ultrathin 4D shell cloth permits a little bit of air trade, however it may possibly nonetheless get swampy in case you are shifting quick. When worn as a midlayer or for stop-and-go exercise in cool climate, it hits a pleasant stability between warmth retention and breathability. Simply don’t anticipate it to double as a real energetic insulation piece for sustained high-output use.

Ought to You Purchase the Black Diamond Deploy Down 0.5 Full Zip Jacket?

Nevertheless, in case your focus is prolonged cold-weather journey, trudging via snowbound terrain, or tough off-trail scrambling, this jacket isn’t constructed to be your sole insulating layer. Whereas its warmth-to-weight ratio is spectacular, the skinny shell and minimal insulation imply you’ll desire a heavier layer close by in harsher situations.

By way of worth, it gives elite efficiency for customers who prioritize weight financial savings and mobility. However for somebody in search of all-around utility, sturdiness, and year-round consolation, it might appear to be a excessive value for a distinct segment piece.

Briefly: purchase it when you’re chasing ultra-light, high-efficiency layers. Skip it when you want a flexible, rugged jacket for general-purpose use.
