Great for running

Really like this jacket! It’s lightweight, comfortable, and fits nicely without feeling restrictive. Perfect for running or just throwing on when it’s a little chilly. Love that it’s practical but still looks cute!
For Runs and Running Errands

I love the versatility of the ACG Lava Loft Training Running Jacket! It’s been perfect as we transition into cooler weather especially when our mornings are chilly and our afternoons are much warmer. I love that it has a slim torso which fits me really nicely. The hip area is tight, which works well for me but I think it would be a problem if I had wider hips. The added details of the thumbholes and dual zippers are a nice touch. The make of the jacket, with thinner puffy strips and then breathable holes had me question how it would perform but I’m pleased that it was the perfect material and balance to keep you warm but let you breath during a run. I love that I can wear this for a run and running errands! I’m excited to put more miles in with this jacket.
Warm and comfortable

I really appreciate how lightweight this jacket is while still providing warmth. I was able to comfortably wear a sweater underneath without it being too tight, fits true to size. The style is very clean and looks good with both athletic wear and with jeans. The inside pocket to use as a stuff bag for the jacket was also a nice feature, it makes it very easy to store it in a purse or backpack if you want an additional layer without the bulk. Highly recommend for the fringe seasons.
