Very nice fit and feel. Ordering more already. Thanks for the sunnys!😎👍
First wear was eye opening. I live in the desert and was skeptical that wool could actually be cool. This sun shirt felt great while I worked in the garden as temps were reaching 92°f. I can't wait to wear it again this weekend.
Hi Jeff, we're so glad to hear you had a great experience with our hoodie! It's wonderful that it kept you cool even in the desert heat. Thanks for sharing your feedback!

One wearing for hiking with my backpack and I have pulls and pills on the right sleeve below the armpit. The shirt was comfortable and kept me cool while in the sun. I didn't wear the hood as I was concerned about over heating.
Hi Juliana, thank you for your feedback. We're glad you found the hoodie comfortable, but we're sorry to hear about the pulls and pills. Feel free to reach out to our customer service for assistance. We appreciate your support!

Absolutely love the sun hoodie by minus33. My wife used one on our recent vacation to Cancun and we both agreed it was necessary for me to acquire one as well.
as always great gear
Pros:
Just wore for the first time on a four day backpacking trip and the loved the fit and feel. The zipper was clutch for cooling off and the pocket came in handy.
Cons:
Shirt is already piling heavily on shoulders and waist where backpack makes contact. I use a hipbelt properly so not much weight is on my shoulders but nonetheless the friction is already deteriorating the fabric. I expect for this to happen over time but not after one trip. So if you just need a sun hoodie to wear around it is very comfy but if you're looking for a backpacking hoodie I would be very hesitant to recommend.
We're glad to hear that you enjoyed the fit and feel of the hoodie during your backpacking trip. However, we apologize for any issues you experienced with the durability of the fabric. We will take your feedback into consideration as we continue to improve our products. Thank you for your support and we hope you continue to enjoy the versatility of the hoodie.
Just completed 1,450 miles of the Great Divide Mountain Bike Route using this hoody as my primary upper body layer; it exceeded expectations and was my favorite piece of kit. Didn't use the zippered pocket as much as I thought I might, but the ¼ zip added versatility that made all my other sun shirts pale in comparison. The front zipper provided a means to regulate body temperature on the few cold or wet days and really shined on the sunny, hot days. The hood had a generous cut that allowed it to be worn under a helmet, with enough ventilation to prevent overheating on the hottest of days. The convenience of machine wash and dry was a key benefit. Fit remained good even after soaking in streams. The gray color deflected the worst of heat in direct sunlight. While it is showing signs of wear and tear with 35 days of constant use, this piece held up very well and I anticipate it will accompany me on many more adventures. This is a versatile piece of technical gear and well worth the money.
One note is that I did not wear a pack on this trip, so cannot speak to the abrasion resistance of the the material, but for my situation the hoodys' performance was outstanding.

Great sun shirt! The sun gets intense up here at 6,300" ASL. This **** is a great way to mitigate that sun exposure. Great for chilly mornings on the mountain bike, and it packs down to nothing. Loving it on the water, great light layer while on the boat or paddling. Plus it has nice long sleeves, which I appreciate having "monkey arms".
Thanks for sharing your love for our Microweight Wool 1/4 Zip Sun Hoodie! We're glad to hear it's been a great way to protect you from the intense sun at such a high altitude. And we totally understand the need for extra long sleeves - 'monkey arms' unite! Happy biking, boating, and paddling!

When I ordered this sun hoodie I really had doubts that it would perform in the heat the way that I hoped, but it is now my favorite. I purchased the Microweight 1/4 zip hoodie for summer hiking here in Arizona. My formerly favorite sun hoodie is synthetic (mostly nylon), and performs well enough late fall through early spring here in the desert, but it is stifling when it gets warmer. I really wondered if this wool hoodie would be much better, and I found out - it is super. So far, I have worn it on several all day hikes in exposed canyons with temperatures in the high 90's and full sun exposure and was extremely comfortable. The cut is comfortable, the coverage is great, and it breathes wonderfully. The synthetic hoodie I have is a bit more durable for rock climbing, but that's not why I got this wool one. For hiking, backpacking, trail running, etc., this is now my number one! (Btw, I am 6'1" and about 180 lbs. and I ordered a size large - perfect fit.)
Hi Scott,
Thank you for taking the time to write such a detailed review of our Microweight Sun Hoodie! We are thrilled to hear that it has become your new favorite for summer hiking in Arizona.

Thank you for choosing our hoodie for your outdoor adventures and we hope it continues to keep you comfortable on your hikes. Happy trails!

Nice piece for very lightweight Merino warmth. Just what you need over a tee shirt for a spring morning layer you'll remove after you get warmed up.

My wife and I love these Hoodies. Perfect for kayaking on lakes and rivers . The zipper on the front is great for cooling off when you are paddling hard or if breezy you can zip it up. Just like the other gear we have purchased from Minus33.
Richard,
Thank you for taking the time to leave us such a wonderful review. It's great to hear that you're enjoying your sun hoodie on the lake! This is one of my personal favorite items to wear for fishing! Thank you for your support and for your feedback. We greatly appreciate it.

I am 6'3" and 190 lbs. athletic build. the fit in the shoulders and chest are perfect for me, and this is the area where some shirts can be too snug. the fabric is very breathable, the hood is an excellent cut that is almost like a scuba style hood, but not quite as restricting. the chest zipper is deep enough for meaningful ventilation, I have the light blue color and find it to be light enough not to be hot in full sun. the sewing is impeccable. I find this to be a thoroughly excellent product and would like to see it offered in a thicker fabric as well. In general, I would say this is one of the most useful tops I own for being active outdoors.
John,

I try to shop NH local companies as often as I can. I also try to wear merino as often as I can. This is an absolute win. Stellar product.
I like the weight, the details like the chest pocket for stashing stuff, but after a 3 day hike in the Dolomites the hoodie is looking pretty rough in a few spots, like where the backpack waist buckle sits, and also in the back where backpack can rub. I know wool is a little more delicate, but figured this blend would at least hold up a little more after just one trip.

Favorite lightweight sun hoodie! Very lightweight and the long zipper makes it easy to take on/off the shirt and provides ventilation if needed.
