Light, light, light...
Hood quite basic.


What's It For? The Diad has one real purpose in life, to be as light possible while still remaining waterproof. It's aimed at fast and light outdoors people who want something they can stuff in their pack or pocket just in case it rains. That's it really. It's not intended to be super durable, just light, compact and waterproof.


The Techy Bits How do you make a very lightweight waterproof jacket? It starts with TNF's HyVent DT fabric, a lightweight material that they describe as 2.5 layer - the inner material is micro-girdded to save weight and the outer uses a fine rip stop.

The key though is the 'Magic Seam' construction. The fabric is hot cut and seams are welded edge to edge using 'state of the art rotary sonic and line-bonding machinery' it says here. The end result, claim TNF, is a saving of 42 grammes in the weight of the garment. That's a lot when the total weight is a shade over 200 grammes.

Finally, you leave out as many unnecessary features as possible, so just a single pocket, no fleecey beard guards and so on.


How It Works First things first, the Diad is light, very, very light. Our medium test jacket weighs a genuine 202 grammes on the OM electric test scales and that's impressive. It also packs small, around the size of a small grapefruit or you can stuff it happily into a Pete's Eats pint mug with only a small muffin top to show...

So it's very small and not very heavy. Happily, it manages to do all that without feeling unpleasantly flimsy unlike some minimalist kit we've seen. The fabric's light but has a nice quality handle to it and isn't too crisp-packety. We wouldn't use it with a heavy pack or rub it regularly against rocks, but it doesn't feel super fragile.

Cut is on the short side with a bit of a droptail thrown in and in classic TNF stye is just a little looser than the 'Performance Fit' designation might suggest. It's hardly baggy, but nor is it Arc'teryx tapered close though it's neater than TNF's boxy standard fit.

It's also not as minimalist as you might think. There are small pit-zip vents tucked away under the arms and they're neat enough to be unnoticeable, though we didn't find them particularly effective. Hem and cuffs are both adjustable and there's a hood with both front and rear tensioners.

The hood's quite minimal with big side cut-outs and only a small peak, so not great for full-on protection, but on a par with a lot of other lightweight jackets designed for summer use.

The fabric's not at all bad either. It's not in the same league as eVENT when it comes to breathability, but it's not bad and while we wouldn't want to use it for sustained high energy activity in warm conditions, it copes fine with normal walking use. And to be fair, this jacket's about weight saving rather than all-round performance.


Initial Verdict


We seem to have spent more time carrying the Diad around 'just in case' than wearing it, but really that's what it's for, and you can't argue with its impressively low weight and bulk - there are few jackets out there which'll give it a run for its money on the scales. Off the top of our heads, there's just the Montane 200, which actually weighs more than 200, the Patagonia Specter Pullover at a claimed 184 grammes and the GoLite Rage jacket at a claimed 200 grammes, though that has no hood.

It also manages not to feel too minimalist when you are wearing it with okay breathability and a nice, non-flimsy feel and you're not short-chaged on the feature side either, though you won't be carrying an OS map in the pocket.

All in all, it just goes to show what The North Face is capable of when they direct their massive resources to a tight, focussed objective. If you're looking for an ultralightweight waterproof and the cut suts you, you won't find much to touch the Diad.
