Granite Gear eVent Uberlight CTF3 Drysack

When Granite Gear introduced the Uberlight CTF3 sacks in 2010, the lightest storage sacks in the known universe, they knew they'd have a hard time improving on them. By figuring out how to bond eVent waterproof-breathable material to the CTF3 “fabric at the bottom of the sack”, they accomplished it! Same features as the original-- ridiculously light, strong, waterproof-- but now with the added advantage of a breathable bottom. As you roll the top down, the trapped air can escape through the end of the bag.
