Ericwrote a review of Sportful Fiandre Gloves on October 31, 2016
Familiarity: I've used it once or twice and have initial impressions
I bought these gloves on sale, as I have had good luck with Sportful products overall. They are well constructed, fit true to size (I'm size L in these and Castelli). They have a nice textured palm without any stupid gel padding patches, a large neoprene cuff that is adjustable via velcro, and they allow reasonable dexterity on the bars for a thermal glove.
However, the notion that these gloves using the OutDry membrane are waterproof is the same as every other glove claiming to be waterproof, and that is crazy. I gave them a 90 minute test on a road ride in light-moderate rain at a temp of 8 Celsius (45 F). My hands were dry for the first 50 minutes, then progressed to soaked by the end. As a guy who rides a lot year round in the greater Vancouver area, I can say the best gloves for riding in the rain when the temp is below about 10 C is neoprene like the Castelli Diluvio. Similar neoprene gloves can be found at any outdoor store selling kayak equipment. One's hands will be wet in the neoprene, but warm. The only caveat is that if it stops raining the neoprene will not do much as the gloves dry and eventually one will have cold hands. That is why the savvy PNW rider never leaves on a wet ride with less than 2 pair of gloves :)
Now, back to the Sportful Fiandre. I think these gloves will prove to be solid performers in very light rain/drizzle and also on dry rides with the temp in the 5-10 Celsius range. Again, they are well built and at the sale price I think they are good value but just don't believe the hype of waterproof.
