Not many other options for a larger seat pack
There aren't very many choices for a 1 1/2 liter pack and I like this one better than the only other one I was able to find (which was too long and skinny). The large size doesn't look or feel large on the bike but holds a lot. It holds a phone very nicely on the internal shelf (keeping it away from everything else in the bag). It's hard to find a bag that's the right size and shape to hold a phone but this one does. It doesn't have a key clip so I added my own. If you have a problem with the velcro rubbing on your shorts, it's probably because you have the grippy side out. All you need to do is reverse it so the fuzzy side is out.

The Jury is In
This is my second Grid Seat Bag, the first becoming unusable after the zipper did not track anymore. That being said, I got 8 years of service out of my first bag, so expecting the same here. The bag is ideal for most of my rides (I use a bar bag on long rides, however). Solid construction. One thing I do is to pack the bag and then cinch it down.

Hard to fit in some saddles
The size is okay. Very small. Fits, small tool kit, co2, bacon strips and holder, no tube. Hard to attach to my selle saddle. Might be good on other saddles. I still like it. Just don't love it, which is okay.

Smaller than expected
Ordered the small bag and was disappointed to see that it is actually smaller than it appears on the pictures, and also smaller than the one I intended to replace. Also, the zipper seems a bit hard to move. So, unless BTD.com takes it back for a full refund I feel that I somehow wasted my money on this.

Very Nice Bag with 1 Caveat
Size Med , but I ride tubeless tires, so no inner-tubes in my seatbag, so I could get by with a Small. Also, no tire irons or patch kit.
I have room for CO2 cart & chuck, 1st Aid Kit, micro Leatherman, Visine bottle of anti-bacterial soap, Topeak micro tool, chain Quick-Link, GU, CC-sized gate key, and 3,000mAh USB charger, although that might have to stay behind if I were using the small size. Lately I've been carrying a medicine bottle filled with GatorAid laid sideways across the top in back.
Love the reflective sides, they show up well at night, and in photographs using flash. Like the wrap-around main strap, and dust/waterproof zipper.
CAVEAT: The Velcro loop around the seatpost has a rough coating on it that will chew up the legs of your shorts. Replace it ASAP with something softer and non-abrasive. I remember distinctly writing Blackburn a nasty-gram 10yrs ago about this same issue. I used a Velcro strap with the soft, fuzzy side out. Works great.

large bag with plenty of room for essentials
This bag is a little bigger than standard but great to hold an oversize phone, tools and a spare tube/co2 cartridge. made of smooth nylon so it doesn't rub

Nice saddle bag
Needed a larger saddle bag to carry my new larger smartphone. It has two separate compartments separated by a soft liner to protect the phone from being scratched from tubeCO2 cartridge. I would have preferred Topeak type clips instead of a large velcro strap.

Nice bag, The large could be even larger
The large is a bit of a weird size. It is just a bit too small to fit a jacket, some tools, and a couple of bars. I would buy something 20% larger.
Quality is high, Zipper quality is high. It definitely keeps the contents dry during some moderate rain.

Big enough
With this pandemic going on and needing a mask i needed more room for carrying a mask, didn't want to put it in jersey pocket. It also has given me room for small bottles of sunscreen, hand sanitizer and my wallet. Great buy.

Perfect
Just enough room for my use. I can get a multi-tool , patch kit, tire levers, wallet, keys and a compact pump. Couldnt ask for more. If youre a gram counter this is not for you, but it just suites me.

New favorite
Even the small size option is roomier than my prior bag. Add that to the easy access zipper panel and secure attachment strap and it stays on securely even on rough gravel and mountain descents. Reflecting side panels are a nice touch too.

Blackburn Grid Seat Bag is small
Easy to mount under your bike seat, but is smaller than I'd prefer. However, it does carry almost everything I need when out and about. (The rest goes into my pockets.)
