The O'Brien Jr. Siege is the waterski built for any kid, from the fearless daredevil who's going to be burning turns within the first few days to those who like to take their time. Built with a forgiving fibreglass and polyurethane construction, O'Brien makes the Jr. Siege forgiving underfoot with a comfortable amount of flex to support skiing at beginner speeds but still stiff enough to turn a buoy in the course. The design principle on the shape of the Jr. Siege is designed to work with the core, creating a ski that will create edge turn and hold with ease while also creating consistent, comfortable and fast transitions in the turns. Altogether, the O'Brien has developed the perfectly rounded kids ski, one ski to rule them all.

The O'Brien X9 waterski boot is built with base-level comfort and ease in mind, taking the core components of a ski boot to make it easy for kids and adults alike. A simple neoprene liner sitting above a plush EVA footbed gives you comfort from underfoot all the way through to your upper ankle. Underneath this is O'Brien's signature superlite chassis that gives you the perfect weight balance with your ski.

Waterski Features

Rocker

  • Flat Spot - Underneath your front foot gives you comfort and stability while also propping you up higher on a platform for control throughout your entire motion from cut to turn.
  • Continuous Rocker - Through the tip and tail allows the ski to always provide a constant level of speed across the wash and allows for a smooth, comfortable turn, drive through the wash, while still having the ability to easily keep that speed into your leading edge.

Flex

  • Flex Rating(1=Soft, 10=Stiff) - 5/10

Core

  • Closed Cell PU Core – The most well-known core in waterskiing, with a tighter knit construction to reduce weight while remaining durable and providing a slightly softer feel meaning you can ski for longer, feeling less tired, while also getting more flex into turns and less rebound when crossing the wash

Laminates

  • Fibreglass Laminates – The most forgiving top layer you can get, a simple fibreglass laminate allows the ski to provide a comfortable flex and smooth arcing turns.

Shape

  • Small Defined Edge Bevel - This makes it easier to turn and lean into your edges and hold the edge through the wash.

Concave

  • Rapid Response Tunnel - O'Briens signature tunnel shape designed to transition from edge to edge with ease and create easier hold through the turns

  • Polished Speed Base - All about promoting greater water flow across the base of the ski to ultimately reduce drag

      Dont wait! Assemble right away! Just in case you need to return it.
      Color: Black, Size: 22" - 4 Panel
      Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

      Smooth, Stable, and Perfect for Flexible Spaces
      Size: 88''W-4 Panel, Color: Grey, Size: 88''W-4 Panel, Color: Grey
      This room divider is incredibly easy to move thanks to its industrial-grade silent casters. It glides smoothly across different floor types with just one hand and without any noise, while the built-in wheel locks keep it firmly in place once positioned, no slipping or unwanted movement. The base with reinforced steel feet adds impressive stability, preventing wobbling even in busy or high-traffic areas. I also love the foldable design, which makes storage effortless when it’s not in use. It folds down compactly and fits neatly into small spaces. I gave only 4 stars because I'm not crazy about the color of the fabric. Otherwise this is a very functional way to separate areas.

      easy to put together, stable and blocks out unwanted eyes.
      Size: 88''W-4 Panel, Color: Grey
      If you live in a high rise building, or where there is lots of foot traffic and can see in your windows, this is a must have. It's portable, can fold down one or two walls and easy to move around. Put together once, and block out light and eyes while tall enough to see over. You can fold it up along the wall, and use it to block out the blinds or light when using a projector so that it's darker. You can use it to partician the room if you share one, and separate your pile of junk from your room so you don't look at it, can take quite a bit of towel weight and clothes and doesn't tip over. Sturdy bottom metal and easy to put together. I got the grey one, and glad I did. I use it everyday and is part of my room decor. I love it, and after using it for a few months it's quite durable. The quality is there for sure. A tad pricey, but worth it. Must have for a private person.

      Well made dividers.
      Size: 88''W-4 Panel, Color: Grey
      Very durable and stable. Once positioned, they stay upright and firm and don't wobble around. Good materials on both the panels and the frame that supports it. Great for any partitioning needs and a fair price for the quality you receive. Highly recommended.
