Never noticed they even sold them until I was out browsing the other day. I never owned a BRP indoor or outdoor cover so I can't compare but I am very impressed with this. I ordered the other day and got it today. I only park in the garage but on trips, I like the fact my spyder is still clean in the morning. In NC, we get this nasty yellow pollen and it gets everywhere so decided to save a few bucks and go with the NR cover. The cover has plenty of room to fit over the spyder, very easy to put on and has the ablity to connect under the bike so not to blow away. Now, I have no idea how in the world I am going to get it small enough to fit back in the bag in came in but that is OK, I will generally leave it out and put it on when in the garage. Will post some pics later but I love the quality and fitting of it so far.
