Thule Chasm Reviews

Great bag for your EDC

By David
Rated 5 out of 5

Well designed as what you'd come to expect from Thule. The top smaller zipper is excellent for your cell phone or sunglasses. The middle compartment offers excellent storage options for your wallet, keys and everyday tech essentials. The main body offers ample storage and accommodates a 16 inch MacBook Pro. The straps are supportive and easily adjustable. This is an excellent everyday bag.

Amazing carry on/travel bag

Bought it last year and it still looks brand new. I take it with me as a carry on in every flight that I have been to internationally and domestically and it is accepted. It fits so much stuff inside and the fact that you can carry it as a duffel or a backpack just makes this the perfect bag. You won’t regret this purchase.
