Well I agree Lululemon is also a great brand that provides wonderful and comfortable clothing. But I also love to wear cheap alo yoga pants too as my budget is not that much high to buy Lululemon clothing everytime so alo pants fits perfect as per my budget.
Just have a look at nice Carbon 38 workout clothes and I am sure you would love their collection. In fact they have latest collection of best summer clothing for gym sessions and it is super trendy. I would also be buying new apparels soon.
