This rain jacket was noted as the lightest rainwear available in 2015. It weighs 120 grams (size M) and is compact enough to fit in the palm of your hand when rolled up. I used it 2-3 times in the mountains, and then stopped using it as I outgrew it. It's a unisex XL size. Equivalent to a men's Montbell L size, or a Patagonia M size. Thank you.
