I originally ordered a medium then switched it for a small. I measured my head to be 56cm. I tightened the medium as much as it would go but it still shifted forward and back a bit. I thought the small might have been too tight the first time I tried it on, but I have worn it a few times now and I love how it fits - feels secure in all directions without squashing my head.
Nice and warm, even on bitter windy days without anything underneath.

Ticked to see that it is now 25% off!

These pants got lots of great reviews, but I can't agree. They seem to pick up any possible dirt and it sticks - e.g. brushing up against the car getting out/in which is not uncommon. Couldn't brush it off, had to wash them.
The fit is quite unflattering in the butt and I can't explain it, but my underwear shifts around somehow whenever I wear these (yes I have tried different pairs thinking it was just me being weird). The zipper on the inside pocket DIGS in to my hip (and they are NOT tight on me) It is just in the wrong place.
Totally would have returned them but it was too much hassle at the time.

I like the streamlined and stylish/feminine look of this jacket. No extra bulk anywhere.
I'm 5'6, 135 and I ordered this in a medium and it fits well. I think a small would have been too small. A bit odd as I also have the C3 full-length down coat in a size small which fits me perfectly so I think the K is a tighter/smaller fit.
Have a bit of trouble with the orientation of the zipper - getting it to hang straight to pull on it. Bit annoying, but not a huge deal.

I bought the stroller wheels (a MUST for just walking around) and this large stroller is so maneuverable it turns on a dime. I can easily push it with both my kids in it with one hand. I also bought the infant sling for my newborn and he is so cozy in there, and I feel he is really secure. Conversions are easy and having the ability and room to bring along the accessory pieces is a great feature. I biked to a local 5k race with kids in the trailer, then swapped out the tow arm for the jogging wheel, ran the race (died) and rode back home (died again!)

Make sure you REALLY tighten the quick release axel. My rear wheel came out of the drop outs from the trailer pushing back on the bike over a few bumps and hills and I wiped out (bike tipped over). However... I had attached the tow arm properly so the safety strap kept the trailer from rolling away, and although I was on the ground the trailer was totally upright - all as it should be. My 2.5 year old thought it was hilarious.

This sling is the best thing. It made my cougar 2 the only stroller I need for my 2 kids, right from the time my 2nd was just a newborn. Lots of room for the toddler and the infant is so cozy and secure. Chariot is the only bike trailer company to offer this feature which is the main reason I chose Chariot for my double stroller / bike trailer / jogger.

Contrary to the other review, the wheels I recieved are exactly what is shown on the website here and exactly what I expected. I have a 2006 Cougar 2 and these are a must have. I love them. Easy to attach and can be carried along when the bike trailer (or other kit) is being used. Very handy when you bike somewhere then need/want to walk. They make the stroller so maneuverable - with both kids in, I can push it with one hand and the stroller turns on a dime.
