Why This Pack Matters for Van Life Climbers
The short version of this Black Diamond Blitz 28 review: it’s one of the lightest genuinely climbable packs you can buy — 28 litres at 408 g — and it makes one very deliberate trade to get there. Understanding that trade is the whole buying decision.
The Trade Every Ultralight Pack Makes
Below roughly 500 g, a pack gives something up: fabric weight, frame, padding, or features. Black Diamond’s answer with the Blitz is to keep the alpine essentials — lid, axe holders, rope strap — and cut everything else, including the burly fabric that makes heavier packs shrug off abuse.
Where the Black Diamond Blitz 28 Sits
It’s built for in-a-day alpine rock, ice and fast multi-pitch missions where the pack goes up the route with you. OutdoorGearLab’s testers called it “an excellent backpack for in-a-day, fast-and-light alpine rock and ice routes” — and equally clearly, not a quiver-of-one. Both halves of that verdict matter.
Build & Materials
How It’s Made
The body is Black Diamond’s UHMWPE “Mini Rip” 100-denier fabric — the same ultra-strong polyethylene fibre family as Dynex/Dyneema, woven into a thin ripstop. That gives an unusually good strength-to-weight ratio, but 100D is still
The body is Black Diamond’s Dynex™ “Mini Rip” 100-denier nylon with a 200d PE panel — 90% nylon, 10% Dynex, the ultra-high-molecular-weight polyethylene fibre woven in as a ripstop grid rather than as the whole cloth. That grid is what stops a nick becoming a tear, but 100d is still thin: it abrades faster than the 200–400d fabrics on heavier packs. OutdoorGearLab’s verdict on the previous generation was blunt — the Blitz “prioritises comfort on route over versatility and durability” — and while the Mini Rip fabric is newer than their test pack, the design philosophy hasn’t changed.
a thin cloth: it resists tearing well, yet abrades faster than the 200–400D fabrics on heavier packs. OutdoorGearLab flagged exactly this — the Blitz “prioritises comfort on route over versatility and durability”.Fittings & Features
You get a top-loading main compartment under
You get a one-handed top closure over the main compartment, a water-resistant zip pocket on the lid, an internal zippered pocket, Black Diamond’s Pick Pockets™ ice-tool attachments with a metal dogbone catch, a colour-coded red rope strap, a height-adjustable sternum strap and a detachable hip belt. The frame sheet doubles as a removable bivy pad, stripping the pack down further for summit pushes. It’s hydration-compatible, and Black Diamond backs it with their Practical Product Lifetime Warranty. What you don’t get: side straps. OutdoorGearLab lamented not being able to lash a picket or skis, and crampons have to travel inside the pack.
a lid with its own pocket, an internal pocket, dual ice axe/pole holders, a rope holder, a height-adjustable chest strap and a detachable hip belt. The back plate and pad are removable — the pad is designed to double as an emergency bivy seat — stripping the pack down further for summit pushes. It’s hydration-compatible, which the Route Rocket generation of small crag packs often isn’t.Capacity & Organisation
What 28 Litres Actually Holds
Twenty-eight litres is the fast-alpine sweet spot: rope on the holder, rack, harness, crampons, belay jacket, food and a litre or two of water all go in for a single-day objective. For a sport-cragging day it’s roomy — rope inside, gear around it — and for anything overnight it’s too small unless you’re a committed minimalist.
Lid, Not Zips
Access is classic alpine: drawcord closure under a lid. It’s weatherproof-ish, secure when hanging, and slower than a panel zip at the base of a sport crag. There’s one internal pocket and the lid pocket for small items — organisation is minimal by design, like most packs in this class.
Strip It Down
The Black Diamond Blitz 28’s party trick is modularity at this weight: hip belt off, frame sheet and bivy pad out, and it sheds meaningful grams for the route itself. Owner reviews on Black Diamond’s own site echo this repeatedly — light, compact, surprisingly spacious — with one Aconcagua climber noting the removable foam liner let him roll the whole pack up inside a larger bag.
Comfort & Carry
On the Approach
Breathable shoulder straps and the thin back plate carry a single-day alpine load well, but this is not a cushioned hauler: with 10 kg+ aboard, a padded, framed pack will beat it on a long approach. OutdoorGearLab’s framing is honest — you sacrifice a little carrying comfort on the approach for what the pack does on route.
On the Route
This is where the Black Diamond Blitz 28 earns its price: it sits close, doesn’t lift over the helmet when you look up, and the stripped profile doesn’t snag on rock or catch tools. For climbing with a pack on — seconding, simul-climbing, easy alpine ridges — it behaves like a much smaller bag than its 28 litres.
Van Life Considerations
Living in a Gear Cupboard
Stripped of its back plate the Blitz packs almost flat, which is ideal for van storage. The caveat is the 100D fabric: don’t cram it against crampon points and ice screws in a packed cupboard. Give it the soft shelf, or keep sharp hardware in a separate box — thin ultralight fabrics age fastest in storage abuse, not on the rock.
The Two-Pack Logic
For van lifers the Blitz makes most sense as the light half of a two-pack system: a burly hauler (Creek-style) lives in the van and carries the mess, the Blitz comes out for the routes that matter. As an everyday town-and-travel bag it works — light, simple, cavernous — but the lid-and-drawcord access is slower than a zip for daily use.
The Wet-Kit Caveat
An Honest Note on Chemicals
Worth flagging if you’ve been following our PFAS coverage: Black Diamond’s own product page states the Blitz contains PFAS and cannot be shipped to California, New York or Colorado. The Route Rocket, by contrast, uses a non-PFC DWR. If PFC-free gear is a buying criterion for you, that’s a genuine point against the Blitz.
The Wet-Kit Caveat
Water-repellent fabric, no rain cover, no sealed seams. Fine for alpine showers and snow; for sustained UK rain, add a liner
Water-repellent fabric, no sealed seams, and no rain cover in the box — though Black Diamond sells one separately. Fine for alpine showers and snow; for sustained UK rain, add the cover or a liner bag.

How It Compares
Black Diamond Blitz 28 vs Patagonia Ascensionist 35
The two lightweight alpine choices. The Ascensionist gives you 7 more litres, tougher fabric and a more supportive carry at 771 g; the Blitz undercuts it by over 350 g and climbs better on route. Big alpine days with heavier loads? Ascensionist. Fast single-day missions where the pack stays on while you climb? Blitz.
Read our Ascensionist 35 review →Black Diamond Blitz 28 vs Blue Ice Warthog 30
Closest rivals in the lineup. Nearly identical volume; the Warthog is ~220 g heavier but uses burlier 210D Robic fabric, adds a 3D ice-tool sleeve and winter-ready coating, comes in two fits rather than one, and is also fully strippable. The Warthog is the more durable, winter-capable tool; the Blitz is the lighter, simpler one.
Read our Warthog 30 review →Blitz 28 vs Petzl Bug
Alpine specialist versus everyday crag pack. The Bug is 18 litres at 665 g, with a laptop sleeve and the best pocket layout in its class — a bag for the whole week. The Blitz carries a full alpine kit at 408 g and strips down for the route. They solve different days: the Bug is the bakery-run crag bag, the Blitz is the one you pack the night before a big objective.
Read our Petzl Bug review →Blitz 28 vs Black Diamond Creek 35
Same brand, opposite philosophies. The Creek is a 1,660 g haul bag that stands up on its own and takes limitless abuse; the Blitz is a 408 g specialist that rewards careful handling. The classic van pairing: Creek hauls everything to the crag, Blitz goes up the mountain.
Read our Creek 35 review →Black Diamond Blitz 28 Review: Final Verdict
The Black Diamond Blitz 28 is a specialist that’s honest about being one — and at this weight and price, that honesty is its strength.
The strengths: 408 g for a real 28 litres, genuinely climbable on route, fully strippable, with the alpine essentials — lid, axe holders, rope strap, hydration sleeve — all present. The trade-offs: thin 100D fabric that won’t tolerate being dragged and crammed like a crag pack, modest approach comfort under heavy loads, and slower lid access than a zip.
For climbers whose calendar includes fast alpine rock, ice and long multi-pitch days — and who already own, or plan to own, a burlier everyday hauler — the Black Diamond Blitz 28 is one of the best-value ultralight alpine packs in Europe right now. If you want one pack for everything, this isn’t it, and it isn’t pretending to be.
Frequently Asked Questions
Is the Black Diamond Blitz 28 durable enough for regular cragging?
It will do it, but that’s not its job. The 100D UHMWPE fabric is very strong for its weight but abrades faster than the 200–400D fabrics on dedicated crag packs. Used as a daily drag-it-everywhere crag bag, it will wear noticeably sooner than something like the Black Diamond Creek 35. Reserve it for the days that justify its weight.
Does the Black Diamond Blitz 28 carry a rope and ice tools?
Yes — a colour-coded red rope strap and Black Diamond’s Pick Pockets™ ice-tool attachments with a metal dogbone catch. That’s the core alpine toolkit, and it’s why the pack punches above its 408 g. Note there are no side straps, so crampons travel inside.
Is the Black Diamond Blitz 28 hydration compatible?
Yes. It takes a hydration system, and there’s an internal zippered pocket plus a water-resistant lid pocket for small items. Note there’s no rain cover included — the fabric is water-repellent, not waterproof, though Black Diamond sells a cover separately.
How small does the Black Diamond Blitz 28 strip down?
The hip belt detaches and the frame sheet doubles as a removable bivy pad. Fully stripped it sheds a useful chunk of its 408 g for summit pushes or technical pitches — and the pack rolls up small enough to stow inside a larger bag on the way in.
