The Female side of these connectors are smaller .205 than the normal .250 male blade type for this size. I found I had to open them up a little for them to work but that is my fault for ordering the wrong ones. The vinyl cracks and comes off when trying to crimp down.

I should've listened when I read other people's reviews and ordered a size up but overall it is nice will fit if you actually go with your right size!

I liked the product by quality but make sure you buy right size. I bought large by taking reference of my friend's harbinger gloves and ordered but when i received, i realized that i should have ordered medium but still you can cope with bigger so i am ok with that.  I recommend product but please make sure you order the right size.

Concerned about the size??? If people would just put enough info in their reviews it would really help ordering this item! Like your dog's measurements: length (low collar to tail base), chest/girth, neck... and weight -- and it makes a big difference to mention what SIZE you bought. (One reviewer wrote about a medium but their listing said small, and the listing doesn't always say the size or the size actually purchased.) Previewing what I wrote here I see it says Small, but this review is about the medium I first bought. So many reviewers have returned the item to order the next size and here I am doing the exact same thing because I thought I made the best choice after reading ALL the reviews for both the blue and the red snowsuit!

My male chihuahua mix is 10.5 pounds, 14" length, 16" chest (deep-chested guy with a thin belly), 10" neck. Height isn't as important to me, altering the leg length is the easier alteration and the jacket legs aren't that long. Based on the reviews here I ordered a medium and it was too big on him, he's swimming in it. I am ordering a small after I write this and will update once I receive it.

A few more measurements for the medium jacket itself (that I haven't returned yet), keeping in mind that these are as best I can figure for this piece and perhaps it will help someone.
Underside Length (from neck to belly, 1" wide velcro runs the whole length, not including 2" collar) = 10.5"
When velcroed the Chest wraps around 25"
When velcroed the Belly wraps around 24"
When velcroed the Neck wraps around 15"
Length is 16" (not including 2" collar) with a 2.25" sewn slit for the tail

One thing I did get from the reviews is that a male dog will need the room for peeing, so it doesn't just go into the belly of the jacket -- that's one of the reasons some people got a larger size and altered the belly of the snowsuit. That is also why I find it so much easier to clothe a female. Another concern perhaps is 'weather' or not one could fit an additional sweater under the suit... Personally I would not base my order on fitting anything bulky under this jacket. I am more concerned that it's not so small or tight fitting that the dog can't jump around or so big that he won't jump or wiggle right out of it. For the little guys this snowsuit is a tad on the bulky side, it's a snowsuit, made from the same poly-filled material as the larger sizes for the bigger dogs; for my 10 pounder it's not overly bulky. It will be plenty warm, it's very well constructed, and I'm going to figure out the right size darn it! It is occurring to me that perhaps the legs and hood from the medium could be zippered onto the small size jacket as a solution for my dog, so perhaps people on here could consider "swapping." I don't know. If this has helped you then click the button under this and lets see how the small fits for us...

Update: Small was just a bit too snug I'm afraid. I wish there was a size right between medium and small. The length was too short so it didn't come to his tail and causes the slight snugness with legs pulling the coat back from his shoulders. The chest was just closable, I would like a teensy bit more room when the velcro is fastened. Not sure what to do now, probably will have the medium altered to fit and return the small. It will be worth the effort but now the cost of his snowsuit has increased by getting it altered. Good luck with your doggie, it will fit some dogs perfectly and others not so perfectly.

The measurements were wrong I ordered a size 4 cuz that's what my measurement suggested to get when I usually wear a size 2.5 or 3. I figured maybe they run small but I ended up returning it n getting my size 2.5 and it fits great!!

How is it when you order specific shoe size and when you get your order one of the shoe orders size is wrong? WARNING!!!!! make sure you check, check , check and double check the order carefully after you place it ( even when the order confirmation states that you orderd the right size)!!!!!!!!! What a pain

Prior to placing my order, I read the reviews, the description, and everything I could find about the sizing. I ordered the XL(US 4-6) and hoped it would fit. I normally wear a size 8/10 as I'm slightly overweight for my height of 5'0". My package arrived yesterday (way earlier than originally expected) and I immediately tried it on. It fits!! I'm so happy!!

Ok, so after reading all reviews I ordered my normal size 7. Received these shoes tonight, slipped my foot into the shoe bed and my toes hung off the front!! I almost ordered a size up (but are out of stock) and decided to check the box again - yes, it says size 7 on the box. Decided to check the shoes strap for sizing and yep, it's says a size 5. I like the shoes so much I was going to try again and order another size 7 (size 7 would have fit) with hopes I would actually received a size 7, but, of course, now the size 7 is out of stock. Needless to say, I am not a happy camper! More care needs to be taken in filling orders as this is the third time I have ordered recently from Amazon and received the incorrect item. Accuracy is as important (or more) than a speedy delivery. Considering cancelling my Amazon Prime!  I'll be very surprised, if this gets posted. BTW - did anyone order a pair of these in orange, size 5, and get a 7 ---let me know :)

Good quality - WATCH SIZING!!  My gosh order at least three sizes ABOVE reality - VERY small in their sizing!!  Having to return "my size"! for one that is alleged gigantic!!  I think they sized on shrunk people

... someone on here stated ordering a size bigger than your actual and I did and it was way too big. Bottom line, unless you try it on first you are going to have a difficult time getting the right fit. ;(

These are in European sizing so be sure to know your size before you order! As long as you order the correct European size it fits perfectly!

Use the sizing chart listed with this product.  I don't usually wear the size I ordered, but by using the sizing chart, I was able to order the correct size that fits perfectly.

I received my suit last nite excited because I plan to take it on my trip next month to Puerto Rico.  Now I did what they said and ordered the next size up from my normal size but it is still TOO SMALL!  So I will be sending it back to order 2x my size maybe three to alleviate this problem.

Make sure you order atleast 2 weeks in advance of when you need the item!!!!

I had previously ordered one in an xlg and it was way to big.  I then ordered a large and it was fine.  This new order, I ordered a large and it was too small.  I have returned it and did order an xlg....hope it works!

I just recieved the new one and is a little too small, so the sizing on this item, runs small!  I am not returning it, as it has become a big hazzle for some a small item.  Feel like the three bears, first one was tooooo big, second one was just right, third one was to small, the fourth one was the wrong item completely an the 5th item size wise is not what I expected, so maybe not exactly the 3 Bears because not one was "just right".....just remember they run small!

It's a great product!  But you must try (in vain, in my case) to determine the correct size.  I ordered the Large, and it is just that - LARGE!  I fill it only with 6 cups of water to make it manageable because it gets too heavy with more than that.

My fault as I accidently ordered the incorrect size and had to return it.  Waiting until after the holidays to re-order the correct size.  Pat
