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

Great fit and makes potty training easier
Size: 3T-4T, Unit Count: 84
These training pants have been a big help during potty training. They fit comfortably and feel soft against the skin, more like real underwear than a diaper. The stretchy sides make them easy for little ones to pull up and down on their own, which really helps with independence.
They do a good job holding small accidents without leaking, and the fun character designs make my little one more excited to wear them. The pack comes with plenty to last through the training phase, which is nice when you’re going through a few each day.
Tip: keep a few extras in the car or diaper bag for outings. It makes potty training on the go so much easier.

Great Pull-ups that Don't Leak!
Size: 3T-4T, Unit Count: 20
I was on the hunt for the perfect potty training pants for my little guy, and Pull-Ups Boys' Potty Training Pants in size 3T-4T turned out to be a great find. We’ve tried a few different brands, but these have been the most reliable. The design is fun and colorful, which my son loves, and it makes him excited to wear them. The fit is spot on for his size (32-40 lbs), and he moves around comfortably without any leaks. The absorbency is impressive – it gives me peace of mind knowing accidents won’t mean a complete outfit change. Overall, these Pull-Ups have made the potty training process a lot smoother for both of us.
There are a few things to note, though. The price is a bit higher compared to some other brands, but I believe the quality justifies it. Also, while they are great during the day, we still need a bit more protection at night. I find myself using an extra layer for nighttime just to be safe. The packaging could also be improved – a resealable option would be nice to keep the remaining training pants fresh and organized. Despite these minor issues, I’m really happy with the product, and my son is well on his way to being fully potty trained.
Pros:
- Fun and colorful design that my son loves
- Perfect fit for 32-40 lbs, allowing comfortable movement
- Excellent absorbency, minimizing leaks
- Helps make the potty training process smoother
Cons:
- Slightly higher price compared to other brands
- Not as effective for overnight use, requiring additional protection
- Packaging lacks a resealable option for convenience

Leak proof training pants

These training pants are amazing. My son uses them whenever he’s taking a nap or sleeping throughout the night. I’ve ordered these multiple times and we’ve never had an issue with leaking.

Great for potty training
Size: 3T-4T, Unit Count: 20
We really like these pull ups and they have worked well for us during potty training. They are easy to pull on and off, which is great for toddlers who are learning to be more independent.
They fit well and do a good job containing messes without leaking. I also like that they feel comfortable and not too bulky, so my child can move around easily.
Overall, these have been a reliable option for us and something we continue to use during this stage.

Preferred by daycare teachers!
Size: 4T-5T, Unit Count: 99
Preferred by daycares because they open and close on the sides and kids can learn to pull on and take on on their own
