I used the HSS Pro Series for a while...it's tough stuff and will do the job! However, it's very heavy. Further, the buckles are heavy, big, cumbersome and rub against your legs and wear on your hunting garments. Recommend looking at any quality harness that does not use the same "car seat" type buckles...perhpas the new ultra light. I switched to the Muddy and really enjoy it...light, quiet and easy, etc., etc. Regardles of the vest you chose, please look at using it with the QSAFE from blindedhunting.com- if you're using a climber that is....you can't go wrong! Good luck.
