Blackburn Grid Seat Bag

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

Its a good bag. Hold emergency repair kit and a multi tool. Only issue I have is color fading away within couple of month. My bike stays in garage, and only when I ride its in the sun

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.

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.

Blackburn does it again, great product, great size, nice reflective material, attractive and versatile. I have one on every bike I ride. Buy one, or two. You can't go wrong.

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.)

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.

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.

This is the largest bag of this type I could find.

It holds the required tools, phone and keys.

Zipper hard to work

I should have gotten larger size

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.

Fits everything I need to bring with me on my rides. Very well made.

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.

Looks good, doesn't bounce around.

I bought this seat bag for my spouses gravel bike. The quality and function is perfect for what she needs it for. At Plenty of storage covering all essentials for emergency repairs.

I purchased this seat bag to replace a Blackburn bag I've used for years. I shopped other brands but decided on buying a Blackburn bag again. I went with the large size, its a bit bigger than I need but still not too large. The water resistant material, practical inner design and great zipper all are nice features. This bag also secures tightly - no worries of it becoming loose. In use for a couple months, no complaints. Great looking bag as well.

Got it within a few days. Just what I expected

Well made; zipper seals out moisture, dust; would recommend this to anyone shopping for a seat bag

love size of bag

Perfect size for tire changing tools
