I am a huge fan of Title Nine, but have no idea about Maple Leaf shipping, sorry. They are women-owned and designed and have decent sales. I own leggings, tops, jackets, sweaters, and more. They use "real" (is there a better word?) women in their catalogs, which I love, and everything is really well-made and durable. Also an excellent source for sports bras! They're having a sale right now: - https://www.titlenine.com/title-nine-sale.html BUT - their sizing is not exactly extensive.
I have Athleta pants and fleeces from 15 years ago that wear like iron. I guess they should, being manmade fiber! When I lived in a drafty house, I wore their Polartec pants all winter long. Now I live in an over-heated condo and wear them for winter walks. They have multiple zipper pockets AND don't collect pet hair.
The reason I don't shop at Athleta any more is purely because of the limited color palette. It seems like everything is black, olive, or grey - an "urban" palette - and I like a lot more color in workout wear.
I've bought a couple Z by Zella shorts from the Rack and like them a lot, especially for the price, but I had to try and return a few before I found a style that really worked.
