    Product Information

    Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.

    Head posts of swivel blocks can be locked at 0 or 90 degrees.

    Great for the price
    I'm really happy with this bag, especially for the price. The two pockets are nice and large enough to fit my kindle, so I was excited about that. The card holders built in to the bag make it easy to just take the few card you need without bringing a whole wallet.

    Perfect Size
    Colors are spot on. This is my second one to own, I love the size because it’s not too big, not too small. I can carry one of these bags everyday for about a year before any wear starts to show. The strap is beautiful and I have gotten compliments on it a lot.

    Favorite Bag
    I LOVE this bag. the bag is super cute. I have a toddler and the bag is constantly getting thrown around and so far it has held up well. The material is thick and the strap is great. The only thing that would make it better would be an interchangeable strap to accessorize.

    Surprising amount of room!
    I am so pleased with the interior space in the pockets of this purse. It's the perfect size to hold keys, phone, and lots of other junk a mom tends to accumulate! The only downfall is the lack of card-holder spaces...only 4 total slots. I purchased another small card holder apparatus to hold all of my necessities.

    Perfect Mini Backpack for almost any occasion! Fits 11 inch ipad
    Color: Black, Color: Black
    Giving 5 🌟🌟 🌟🌟🌟, even if I havent used it yet! because it: -arrived in perfect good packaging, protected and nothing missing. -11 inch ipad fit with its own pocket(although it did reach the very top of the bag and can feel its corners) - can fit 2 regular plastic bottled water on both sides - coin pocket(tho I'll be putting coffee candies and mint instead) - spacious enough for mini snacks or notebook/light books. - has 2 pockets inside - 3 pockets outside(1 at back, 2 at front) Good value for money. Good for travels!(be using for camping). And I think its water resistant. It is a simple, cute, very functional bag for many occasions Wish: that the strap would be a bit longer, although I did have extra 2.5 inches before it rested comfortably at my lower back.
