I picked up a Black Diamond Stormline from Drifters the other day, haven’t had a huge amount of time to put it through the paces yet, but it handled a rainy and snowy morning on top of Table Mountain perfectly. Stood up well to the rain and felt fairly breathable plus ticked all the boxes I wanted (Pitzips, adjustable cuffs, hand pockets and a structured hood). Packs fairly small into its own pocket, and not too hefty (Apparently 290g).
Can’t comment on longevity, but it feels well put together and the seam sealing is all spot on. My only issues were the rainproof zip itself feeling a little finicky, and the hand pockets being bonded to the jacket surface. Had forgotten my gloves and wasn’t so happy I couldn’t get my very cold hands into the pockets of my down under the rainjacket.
I also bought it at the drifters store only to spot later that it was like R300 cheaper on their website
