Rated 5 out of 5 by from Definitely makes my climbing easier! So far I have only used it indoor, but it is definitely making my climbing easier. I could put my phone in the big pocket (BTW my Motorola phone is about the same size as iphone plus), my earphone in the hidden pocket, and protein bars in the mesh pocket. It saves me trips between the walls and locker room and give me access to everything I need. I could only imagine how handy it will be when I climb outdoors!

Rated 5 out of 5 by from Makes storage/ keys phone ect nice This is a bomber Chaulk bag, it has tons of storage. So instead of carrying items in your pocket and having to finagle your harness to get to them; this is way easier to have!

Rated 3 out of 5 by from Keeping my stoke high Ever wish it was easier to bring those peach rings or energy gummies up the wall with you? This bag makes hitting even the local gym easy with my keys and wallet in my chalk bag.. All I ever need it my shoes and this chalk bag.. In between most sizes its not as large as a chalk bucket but is much larger than most barely fist size chalk bags.. Highly recommended if you are cross disciplined you can utilize this baby all the time!

Rated 2 out of 5 by from Decent Bag Material, Not Such Decent Cord Material I used this bag consistently while bouldering several times a week for 3-4 months and it functioned as expected until the cord that is used to tighten the chalk sac broke. Now I have a an OK bag that spills chalk every now then.

can someone please post a pic of how you use the bungee cord underneath to secure the light jacket? it sounds like a great idea but i'm concerned about how secure it is and not sure i'm doing it right. thanks!
