Okay, this FIGHTSENSE sauna suit is no joke - the sweat is absolutely unreal! I've been using it for my boxing training sessions, and the amount of perspiration is incredible. The suit is made from heavy-duty EVA coated nylon that's completely waterproof and windproof. The two-piece set includes a long sleeve pullover top and pants with elastic gatherings at the wrists, waist, and ankles that create a tight seal to really trap that body heat. The double-stitched seams are seriously durable - I've been using mine for months with intense workouts, and there's no ripping or tearing whatsoever. The suit increases sweat output dramatically - I'd say it's easily 70% more than my normal workouts. It's designed as unisex and comes in sizes from M all the way up to 8XL, so there's a fit for pretty much everyone. The sleek design with color patterns actually looks pretty cool - way better than those cheap plastic suits. I machine wash mine after each use (cold water) and it's held up perfectly with no deterioration. While it's amazing for shedding water weight quickly before events, I make sure to stay super hydrated and don't use it for every workout. The heat radiation technology really works to reflect your body heat back to you, creating that sauna effect. If you're looking to intensify your workouts and maximize sweat, this suit delivers serious results - just remember to drink plenty of water and listen to your body!
