You can choose a refund to your original payment method, an exchange, or store credit.
Items must be unused and in original condition, including all tags, packaging, and accessories.
Please do not use the shoe box or product packaging as the shipping box. Please place it inside a separate shipping carton.

For everyone's safety and due to industry standards, the following items are not refundable unless they arrive defective:

Climbing gear (harnesses, carabiners, ropes, etc.)
Food items

Special order items

If you believe one of these items is defective, contact us so we can review your situation and make it right.

Oversized Items — $40 Flat Return Shipping Fee

Some bulky products (large tents, certain hard goods, oversized equipment, and similar) ship via oversized carriers and are flagged as Oversized Item on the product page before you complete your order. The flat $40 return shipping fee that applies to these items is disclosed at the time of ordering, so you'll know upfront if your item qualifies.

If you later choose to return the item, the $40 return shipping fee will be deducted from your refund or store credit when your return is processed. The returns portal will surface this fee for you again when you start the return, so there are no surprises.

If your oversized item arrived damaged, defective, or as a result of our error, the $40 fee is waived and return shipping is on us. If you're unsure whether your item qualifies as oversized, or you have questions before placing an order or starting a return, please reach out — we'd rather talk it through with you first so you aren’t caught off guard!

How to Start a Return or Exchange

The fastest way to start a return or exchange is right in our returns portal. Enter your order number and zip code, choose the item(s) you'd like to return or exchange, tell us why, and we'll generate a prepaid shipping label for you on the spot.

Shipping Your Return

Standard returns and exchanges include a free prepaid shipping label, generated automatically when you start your return in the portal.

Pack your item securely with all tags, accessories, and original packaging included.
Drop the package at the instructed drop off location.
If your return is due to our error or a defective item, shipping is always on us — no exceptions, including no oversized-item fees.

Refunds and Original Payment Methods

Refunds are issued to your original form of payment unless store credit or exchange are selected.
For oversized items, the $40 flat return shipping fee is deducted from your refund, store credit, or exchange balance.
Once we receive and inspect your return, your refund, exchange, or store credit will be processed as quickly as possible.
You'll get an email confirmation when your refund or exchange has been processed.

Our Waffle Knit Thermal Crewneck is knitted with thick Peruvian cotton blended with a bit of polyester. Soft and comfortable against the skin, the waffle-knit construction traps a layer of warm air for exceptional thermal retention. Worn solo or under a jacket, this dependable classic style provides versatile comfort in a wide range of temperatures. Rib-knit cuffs stay in place for easy layering, and side-seam hem slits allow ease of motion.

About The Brand

Filson has outfitted people who work outdoors since 1897, when C.C. Filson began kitting out prospectors headed north to the Klondike. The promise then was the same one on the label today: might as well have the best. That means oil-finish Tin Cloth and Shelter Cloth waxed canvas that turns brush, weather, and abrasion; Mackinaw wool that stays warm wet; brushed cotton flannel and moleskin cut for a full day of motion; and hardware chosen to outlast the garment. Filson builds gear to break in rather than wear out, and backs it with a lifetime guarantee. At Mountain Sports, we love Filson because it is honest, repairable, heirloom-grade kit — the jacket you hand down, not the one you replace.

Filson Sizing Chart

Measurements are in inches. These are body measurements, not garment measurements. Use a flexible tape measure and record your body measurements to choose your best size. This is a general guide — fit varies between products, dependent on their intended use.

Men's Tops (shirts, jackets and outerwear):

Size	Neck	Chest	Waist	Natural Waist	Pit to Pit	Arm Length
XS	15.5"	35.5"	29"	35.5"	16.5"	33"
SM	16.25"	38.5"	32"	38.5"	17.25"	34"
MD	17"	41.5"	35"	41.5"	18"	35"
LG	18"	44.5"	38"	44.5"	18.75"	36"
XL	19"	47.5"	41"	47.5"	19.5"	36.75"
2XL	20"	50.5"	44"	50.5"	20.25"	37.5"
3XL	21"	53.5"	47"	53.5"	21"	38.25"

To measure: Neck — around the base of the neck where a collar sits. Chest — around the fullest part of the chest, under the arms. Waist — where the waistband of your pants normally sits. Arm length — from the center at the base of the neck, over the shoulder and elbow, to just past the wrist bone.

Filson's Tin Cloth and waxed-canvas jackets are cut trim to wear over a shirt. If you are between sizes or plan to layer, order up one size.

Men's Bottoms (pants — numeric waist):

Waist Size	Body Waist	Hips
28	28"	34.5"
30	30"	36.5"
32	32"	38.5"
33	33"	39.5"
34	34"	40.5"
35	35"	41.5"
36	36"	42.5"
38	38"	44.25"
40	40"	46"
42	42"	47.75"
44	44"	49.5"
46	46"	51.25"
48	48"	53"

Filson men's pants are sold by waist and length (for example 34 waist, Regular length). To check length, measure a pair of pants you already own along the inner seam from the crotch to the bottom of the hem: 30" and under is Short, 30–32" is Regular, 32" and over is Long.

If your measurements fall between sizes, choose the larger size for a looser fit or the smaller size for a snugger fit.
