Plus size waterproof jacket that doesn't make you sweat?

[JiraffDeSaki]

I hate dog walking when it's rainy but muggy - I do 2 - 4 miles a day but I'm pretty fat, so in summer my core temp gets very high and then the sweat pours off me. 😳

All fine and good in a breathable top, but wearing a jacket in summer is hell - I wore one this morning and there wasn't much rain, but on the inside I was drenched - sweat soaked the wrists of the jacket and my t-shirt was wet like it had come out of the washing machine! Eww!

Another jacket consigned to charity for someone less sweaty. Has anybody found a decent breathable walking jacket that isn't too clammy and hot, but keeps the rain off? I have a couple of Regatta jackets that are good but they are too heavy for summer - I'd like something thin like a type of cagoul, but don't they make you sweat too?

I've tried the cheap ones from Mountain Warehouse but they were awful. I'm also a bit limited by being a size 20-22. I don't mind a men's jacket?

I have this. I just get wet in summer, rain is nicer than sweat.

Im out and about in all weathers and Berghaus have never let me down. Get a mans XL and go for a fleece with a Gore-tex coat. The draw back is the cost a lot but thats a jacket and fleece combo that with good looking after, should last 20 plus years. For sweating, id recommend wearing a base layer, taking the fleece out and just wearing the jacket. You can get a peaked hood so the hood will stay up through all rain.

I’ve had mine just coming upto 20 years and it survived the flooding in 2007 where I was bone dry after that. The fleece is PolarTech lined which is a cosy and warm fleece.

Its an investment, just dont get rubbish like Karrimor which will fall apart.

I very rarely wear a proper waterproof for dog walking. I have a softshell jacket with a good hood with a peak and underarm zips and wear merino underneath. Rain has to be biblical for me to actually get wet and uncomfortable.

@Thatsthebottomline BERGHAUS yes that was it, that was the man's big coat with a fleece inner that I used for working with horses years ago! Not Regatta as I thought. Never got sweaty inside and never got wet from the rain, I had the best jacket on the yard and it was my stepdad's. 😊 Wonder how much they are now...lets see what sort of hideous error I've made with the Gore-tex Adidas one I've ordered then I might return to a man's Berghaus.

@DataPup The soft shell jackets always seem kinda "thick" to me - I'm usually sweating by the time I've got two dogs ready and laced up my boots, and I would find wrapping the slightest bit of warmth around me at that point absolutely unbearable. In the depths of winter I rarely use the quilted inner of my long Regatta coat - I wear a thin wicking top and just the outer coat, add a scarf and hat if it's under 8 degrees outside. Wearing a raincoat in 18 degrees is torture! 🤣

I also really rate alpkit. More and more of our outdoor stuff is from there. Same quality as much more expensive outdoor brands and very reasonably priced for what you get.

I see waterproof outerwear as one of several layers. If you combine a waterproof jacket over a cotton shirt, for example, the moisture inside can't escape outwards, so will drench your other layer. The only way to escape that in my experience is to wear a fleece jacket or shirt in between, that will provide the barrier and crucially also includes the arms of the coat.
If you choose a ligher fleece for summer, it is not that warm but will still work as buffer. Alternatively, a (long sleeve) shirt from an outdoor or sports brand that wicks away moisture could work in summer.
So essentially adding to what @sashh & @Thatsthebottomline mentioned, and I find it useful to stack some thin layers of clothes instead of one thicker fabric.

I find that softshell works best in cold and dry weather, otherwise I feel too wrapped up, too.
