It's hard to top the Yeti. And every year, the bar gets monstrously higher. Meet the Katron Yeti. 100% classic union suit goodness plus 100% high performance materials and design.

The fit: same as it ever was, with a generous cut through the chest, hips, and seat (where does a Yeti sit? Wherever it wants to). The materials: this Yeti is technically legit. Take it to the slopes, trails, or ice cave party because it's the total package: the Katron Woven outer fabric is wind and water resistant; the Primaloft® insulation keeps you warm and dry without bulk; and and the Polartec® PowerStretch at the side panels, cuffs and collar will have you loving the soft and comfy details of your super suit. In addition to its easy on/off full front zipper and slightly elasticized leg openings, there are four, secure zippered pockets for all your doo-dads and goodies. Put some wow in winter. The Yeti never disappoints.

Love this suit

Bought this suit on a whim as I've always wanted a one piece suit.
It has DELIVERED! I love it as a quick thing to put on to drive kids to school or walk the dog, and it is also my go-to for putting baby in carrier (no bulky coat that rides up in the back).
I am about 5'7" 140 lbs and have the small. I would say I'm average, maybe a bit taller than average height and it fits me perfectly so not sure how sizing would be for someone petite.
Love the green colour because it is different than most other winter clothing.
The material is a great weight and roomy enough to dress in layers underneath.
A hood might be a good addition to the design but it it also pretty great and less bulky without it.
Love the pockets.
Everyone I see asks me where I got this suit!

May never take it off

I have Reynaulds and I’m always cold. Multiple blankets, quilted
sweatpants, beanies, gas fireplace, still cold. I put this on today and I am is snug as a bug. I’m really glad I made the decision to buy this because I wasn’t sure if it was going to be too much… since it looks like outerwear

Almost perfect…!

This is my first Yeti purchase, as I have been eyeballing it since last year. I absolutely love the concept of this, which is why I finally decided to purchase it. For reference, I am 5’6” and 113 lbs with a slender build. I ordered the size small, but hesitated, knowing that I am usually an XS/XXS (alas, these sizes aren’t offered in this!!) This fits perfect in the upper body area (arms, bust, shoulders), but the torso on this is LONG..!! I don’t consider myself short at 5’6”, but the crotch in this hangs halfway to my knees. I understand that it’s supposed to be roomy to fit over clothing, but it looks a bit absurd on me. If I pull the lower section up about 3 or 4 inches, it is perfect with room to spare. I may keep it despite this, just because I love the concept of this & the weight is perfect. I will try to see if I can have it alterated. I wish it was offered in XS or tall/regular sizes for different lengths. I would just caution anyone who is on the shorter side or short-waisted on this one! Other than that, it’s perfection!

Yeti is amazing

This yeti suit is like a hug, a marshmallow and a wearable sleeping bag, all in one. I ordered it for Ragnar Trail races, fall/winter outdoor sports activities and general adventures. I can wear pants and sweatshirt underneath and still feels comfortable. I’m 5’3, 135 and got a small.
